NAS vs Cloud Storage: 5-Year Cost Comparison
Before diving into specific devices, here's why a NAS makes financial sense for anyone storing more than 2TB of data.
| Factor | NAS (4TB usable) | Google One (2TB) | iCloud (2TB) | Dropbox (2TB) |
|---|---|---|---|---|
| Year 1 Cost | $499 (NAS + 2x4TB drives) | $120 | $120 | $120 |
| Year 2 Cost | $0 | $120 | $120 | $120 |
| Year 3 Cost | $0 | $120 | $120 | $120 |
| Year 4 Cost | $0 | $120 | $120 | $120 |
| Year 5 Cost | $0 | $120 | $120 | $120 |
| 5-Year Total | $499 + ~$200 electricity | $600 | $600 | $600 |
| Usable Storage | 4TB (RAID 1) | 2TB | 2TB | 2TB |
| Cost per TB | ~$175/TB | $300/TB | $300/TB | $300/TB |
| Privacy | You own the data | Provider holds keys | Provider holds keys | Provider holds keys |
| Speed (LAN) | 110+ MB/s | 10-50 MB/s (ISP dependent) | 10-50 MB/s | 10-50 MB/s |
| Monthly Fees | ~$3.50 electricity | $10/month | $10/month | $10/month |
| Offline Access | Full access always | Internet required | Internet required | Internet required |
The break-even point: A NAS becomes cheaper than cloud storage subscriptions in roughly 14-30 months depending on your capacity needs. At 10TB+, the savings are dramatic — 10TB of Google One costs $150/month ($9,000 over 5 years), while a 4-bay NAS with 10TB usable storage costs approximately $800-$1,000 total.

Individual Reviews
#1. Synology DS224+ — Best Overall NAS for Home
The Synology DS224+ earns the top spot because Synology's DiskStation Manager (DSM) software is, by a wide margin, the best NAS operating system available. Setting up file sharing, photo backup, media streaming, and remote access takes minutes — not hours of command-line configuration.
| Spec | Detail |
|---|---|
| Bays | 2 x 3.5"/2.5" SATA |
| CPU | Intel Celeron J4125, 4-core, 2.0GHz (burst 2.7GHz) |
| RAM | 2GB DDR4 (expandable to 6GB) |
| Networking | 2 x 1GbE RJ-45 |
| USB | 2 x USB 3.2 Gen 1 |
| Max Raw Storage | 36TB (2 x 18TB) |
| File System | Btrfs, EXT4 |
| Power Consumption | 20W (access) / 6W (HDD hibernation) |
| Dimensions | 165 x 108 x 232.2 mm |
| Price | $299 (diskless) |
Pros:
- DSM 7.2 is the gold standard of NAS software — web-based interface looks and feels like a desktop OS. Setup wizard gets you running in under 10 minutes. Package Center installs apps (Plex, Docker, Surveillance Station) with one click. No command line needed, ever
- Intel J4125 with Quick Sync enables hardware-accelerated Plex transcoding — convert 4K to 1080p on the fly for devices that can't play 4K natively. Handles 2-3 simultaneous 1080p transcodes with CPU usage under 50%. Requires Plex Pass ($5/month or $120 lifetime)
- Synology Photos replaces Google Photos for free — AI-powered face recognition, automatic timeline organization, mobile app with instant backup, and shared family albums. No subscription fees, no storage limits beyond your drives, and complete privacy
- Hyper Backup provides enterprise-grade backup to USB drives, remote Synology NAS, or cloud services (AWS S3, Azure, Google Cloud, Backblaze B2) — versioned, deduplicated, and encrypted. Set it once and forget it
- Synology Drive syncs files across Windows, Mac, and mobile — selective sync, on-demand file streaming, and team folder sharing. A self-hosted Dropbox replacement with no monthly fees and no storage caps
Cons:
- 1GbE networking limits transfer speeds to ~110 MB/s — adequate for most home users but a bottleneck for 4K video editing or large file transfers. No 2.5GbE upgrade option without a USB adapter
- 2GB RAM is tight when running multiple Docker containers, Plex, and Surveillance Station simultaneously — the $30 upgrade to 6GB is practically mandatory for power users
- Synology drives are increasingly pushed through compatibility warnings — third-party drives work fine, but DSM displays nagging notifications if you don't use Synology-branded (more expensive) drives
- 2-bay design means RAID 1 (mirroring) cuts your usable storage in half — buy two 8TB drives and you get 8TB usable. No RAID 5 option with only 2 bays
- No M.2 NVMe slots for SSD caching — random read/write performance stays at HDD speeds
Who it's for: Home users who want the easiest possible NAS experience with the best software ecosystem. Families looking to replace Google Photos, back up all their devices, and stream media to TVs — without becoming a sys admin.
#2. Synology DS925+ — Best NAS for Power Users
The DS925+ is Synology's latest 4-bay flagship for prosumers, upgrading the DS923+ with 2.5GbE networking out of the box, M.2 NVMe slots for SSD storage pools, and the same bulletproof DSM software.
| Spec | Detail |
|---|---|
| Bays | 4 x 3.5"/2.5" SATA |
| CPU | AMD Ryzen R1600, 4-core, 2.2GHz |
| RAM | 4GB DDR4 ECC (expandable to 32GB) |
| M.2 Slots | 2 x M.2 2280 NVMe (PCIe 3.0) |
| Networking | 2 x 2.5GbE RJ-45 |
| USB | 2 x USB 3.2 Gen 1 |
| Expansion | 1 x eSATA (DX525 for 5 additional bays) |
| Max Raw Storage | 80TB (4 x 20TB) |
| File System | Btrfs, EXT4 |
| Power Consumption | 38W (access) / 10W (HDD hibernation) |
| Price | $620 (diskless) |
Pros:
- 2.5GbE networking built-in delivers up to 280 MB/s transfer speeds — 2.5x faster than the DS224+'s 1GbE. Large file transfers (video projects, photo libraries, VM images) complete in a fraction of the time
- M.2 NVMe SSD slots can be used as storage pools (not just cache) since DSM 7.2 — create a fast SSD volume for frequently accessed files, VMs, or databases while keeping bulk storage on HDDs
- ECC RAM prevents silent data corruption — Error-Correcting Code memory detects and fixes single-bit errors before they corrupt your files. Critical for long-term archival storage. Expandable to 32GB for heavy Docker/VM workloads
- Expandable to 9 bays with the DX525 expansion unit — start with 4 drives and add 5 more without migrating data. Future-proof storage that grows with your needs
- Read speeds of 522 MB/s and write speeds of 565 MB/s with link aggregation and NVMe caching — approaches SATA SSD performance for cached workloads
Cons:
- AMD Ryzen R1600 lacks Intel Quick Sync — Plex transcoding is software-only, limiting you to 1-2 simultaneous 1080p transcodes. If Plex is your primary use case, the DS423+ or QNAP TS-464 (both Intel) are better choices
- $620 diskless means the total investment is $920-$1,400+ after adding 4 NAS drives — entry cost is significantly higher than 2-bay options
- PCIe 3.0 M.2 slots (not PCIe 4.0) limit NVMe SSD speeds — not a practical issue for most NAS workloads, but worth noting for users expecting full Gen 4 performance
- Overkill for users who just need photo backup and basic file sharing — the DS224+ does those jobs equally well at half the price
Who it's for: Photographers, videographers, and home lab enthusiasts who need 4+ bays, fast networking, SSD caching, and room to grow. Users running Docker containers, virtual machines, or Surveillance Station with 8+ cameras.
#3. QNAP TS-464 — Best NAS for Media and Plex
The TS-464 is the ultimate Plex media server NAS, pairing an Intel N5105 CPU with Quick Sync transcoding, dual 2.5GbE ports, HDMI 2.0 output, and 8GB of RAM — at $150 less than the Synology DS925+.

- Dual 2.5GbE ports with port trunking deliver combined throughput of up to 589 MB/s — faster than any single-port NAS at this price. Ideal for 4K video editing directly from the NAS
- HDMI 2.0 output connects directly to your TV for 4K 60Hz playback without needing a separate streaming device — use QNAP's HD Station app or Kodi for a built-in media center experience
- 8GB RAM out of the box handles Docker containers, VMs, Plex, and Surveillance Station simultaneously without slowdowns — no RAM upgrade needed for most power users
- $449 undercuts the Synology DS925+ by $171 while offering Intel transcoding that the AMD-based DS925+ cannot match, dual 2.5GbE, and HDMI output that Synology doesn't offer
Cons:
- QTS 5 software is functional but less polished than Synology DSM — the interface has more options but is cluttered, menus are deeper, and the learning curve is steeper for beginners
- QNAP's security track record includes multiple vulnerability disclosures (Deadbolt ransomware in 2022) — while patched, security-conscious users should enable auto-updates and 2FA immediately
- No Btrfs support on standard QTS (only EXT4) — for snapshot-based data protection, you need QuTS hero (ZFS), which requires a clean install and is more complex to manage
- Fan noise under load is noticeable in quiet rooms — the 92mm fan ramps up during sustained transfers or transcoding. Not ideal for living room placement without aftermarket fan replacement
Who it's for: Plex enthusiasts who need the best transcoding performance under $500. Users who want HDMI output to connect their NAS directly to a TV. Content creators who need fast dual-2.5GbE transfers for video editing.
#4. UGREEN NASync DXP2800 — Best Newcomer NAS

- Btrfs support provides snapshot-based data protection, inline data checksums, and self-healing file system capabilities — features typically found on more expensive Synology and QNAP devices
- ADM (ASUSTOR Data Master) operating system is clean and intuitive — not as feature-rich as DSM but significantly easier to navigate than QTS. App Central offers Plex, Docker, Portainer, and 200+ other applications
- Read/write speeds up to 283/280 MB/s over 2.5GbE — saturates the network link for sequential file transfers. Faster than any 1GbE NAS regardless of CPU or drive configuration
- Hardware AES-256 encryption runs at near-full speed without CPU overhead — encrypt your entire volume without sacrificing transfer performance. Critical for users storing sensitive personal or financial documents
Cons:
- Realtek ARM CPU cannot transcode Plex streams — Direct Play only (clients must natively support the video format). If you need Plex transcoding, spend $180 more on the QNAP TS-464
- 2GB RAM limits the number of simultaneous services — running Docker, Plex Direct Play, and Surveillance Station simultaneously may cause slowdowns. RAM is not user-upgradable
- ASUSTOR's app ecosystem is smaller than Synology's or QNAP's — fewer first-party apps and less community-contributed packages
- Brand recognition is lower — fewer online guides, tutorials, and Reddit troubleshooting threads compared to Synology or QNAP communities
Who it's for: Budget buyers who need RAID 5 across 4 bays with 2.5GbE networking but don't need Plex transcoding. Users who Direct Play media (4K TV, Apple TV 4K, Nvidia Shield) and want the cheapest 4-bay entry point.
#6. TerraMaster F2-223 — Best 2-Bay Value NAS
The F2-223 combines an Intel N4505 CPU with dual 2.5GbE ports and 4GB RAM for $200 — the cheapest Intel-powered NAS with multi-gigabit networking, making it a strong Plex and Docker platform on a budget.

| Price | $200 (diskless) |
Pros:
- $200 for an Intel CPU with dual 2.5GbE is the cheapest path to hardware-accelerated Plex transcoding with multi-gigabit networking — $99 less than the Synology DS224+ (which has 1GbE only)
- Dual 2.5GbE ports support link aggregation for combined 500+ MB/s throughput — or connect to two separate networks for isolation. More networking flexibility than any other sub-$300 NAS
- 4GB RAM expandable to 32GB via two SODIMM slots — future-proof for Docker containers, VMs, or surveillance camera recording. The DS224+ maxes out at 6GB
- Intel N4505 Quick Sync supports 1-2 simultaneous Plex transcodes — adequate for most households where 1-2 family members stream at once. Not as powerful as the N5105 in the TS-464 but sufficient for casual Plex use
- M.2 NVMe slots for SSD caching improve random read performance for photo libraries, databases, and Docker volumes — a feature absent from the DS224+ and TS-233
Cons:
- TOS 6 (TerraMaster Operating System) is less polished than DSM or QTS — functional for file sharing and media but lacks the depth of first-party apps. Backup solutions are basic compared to Synology Hyper Backup
- Dual-core N4505 is slower than the quad-core J4125 in the DS224+ for multi-threaded tasks — background indexing, photo AI, and Docker containers run slower when multiple services compete for CPU time
- TerraMaster's mobile apps receive mixed reviews — backup and remote access functionality exists but the user experience lags behind Synology Drive and QNAP QuMagie
- Smaller community means fewer tutorials and troubleshooting resources — you're more reliant on TerraMaster's official support
Who it's for: Budget buyers who want Intel Plex transcoding and dual 2.5GbE networking without paying Synology prices. First-time NAS users who need a capable platform for under $200 and are comfortable with less polished software.
#7. QNAP TS-233 — Best Budget NAS
The TS-233 is the most affordable NAS from a major manufacturer that still delivers a genuinely useful experience — automatic phone backup, basic media streaming, and file sharing for $169.
| Spec | Detail |
|---|---|
| Bays | 2 x 3.5"/2.5" SATA |
| CPU | ARM Cortex-A55, 4-core, 2.0GHz |
| RAM | 2GB DDR4 |

| USB | 1 x USB 3.2 Gen 1, 2 x USB 2.0 |
| NPU | Built-in Neural Processing Unit |
| Max Raw Storage | 36TB (2 x 18TB) |
| File System | EXT4 |
| Power Consumption | 15W (access) / 5W (HDD hibernation) |
| Price | $169 (diskless) |
Pros:
- $169 is the lowest entry point for a NAS from QNAP, Synology, or ASUSTOR — add a single 4TB drive ($80-$100) for a complete personal cloud under $270. The most accessible path to owning your data
- Built-in NPU (Neural Processing Unit) accelerates face and object recognition in QNAP's QuMagie photo management app — browse photos by person, location, or scene without taxing the ARM CPU
- 15W power consumption is the lowest on this list — costs approximately $1.50/month in electricity running 24/7. Over 5 years, electricity costs total roughly $90, less than a single year of cloud storage
- QTS 5 with full app ecosystem — despite the budget hardware, you get the same QTS software as the $449 TS-464. File Station, QuMagie, Multimedia Console, and hybrid backup are all included
- Whisper-quiet operation at under 20 dB during HDD hibernation — suitable for bedroom or living room placement where noise matters
Cons:
- ARM CPU cannot run Plex, Docker, or most x86 applications — limited to QNAP's own media apps (Multimedia Console, Video Station) for streaming. No hardware transcoding of any kind
- 1GbE networking caps transfers at ~110 MB/s — noticeably slow when transferring large video files or photo libraries. No upgrade path to 2.5GbE
- 2GB non-upgradable RAM limits multitasking — running QuMagie's AI photo processing slows down the entire system. Stick to 2-3 active services maximum
- EXT4 only (no Btrfs) — no snapshot protection, no inline checksums, and less advanced data integrity features compared to Btrfs-capable NAS devices
- USB 2.0 ports are nearly useless for external drive backup — transfer a 1TB USB drive at 30 MB/s takes over 9 hours. Only one USB 3.2 port available
Who it's for: First-time NAS buyers who want the absolute cheapest entry point for centralized file storage and phone backup. Users who don't need Plex, Docker, or power-user features and just want a private cloud for documents and photos.
Buyer's Guide: How to Choose a NAS for Home Use
How Many Bays Do You Need?
| Bays | Usable Storage (RAID 1/5) | Use Case | Typical Cost |
|---|---|---|---|
| 2-bay | 50% capacity (RAID 1 mirror) | Personal backup, photos, documents | $170-$300 |
| 4-bay | 75% capacity (RAID 5) | Media server, multi-user, surveillance | $270-$620 |
| 5+ bay | 80%+ capacity (RAID 6) | Professional, video production | $800+ |
Rule of thumb: Buy one bay more than you think you need. Storage needs grow 25-40% annually. A 2-bay NAS that's "plenty" today may feel cramped in 2 years.
RAID Levels Explained Simply
- RAID 1 (Mirror): 2 drives store identical copies. One drive fails? No data lost. You lose 50% of total capacity (two 8TB drives = 8TB usable). Best for 2-bay NAS.
- RAID 5 (Striping + Parity): 3+ drives. Data spread across all drives with parity for recovery. One drive fails? No data lost. You lose one drive's worth of capacity (four 8TB drives = 24TB usable). Best for 4-bay NAS.
- SHR (Synology Hybrid RAID): Synology's proprietary RAID that allows mixing different drive sizes efficiently. Same protection as RAID 1/5 but wastes less space when drives aren't identical. Recommended for Synology users.
- JBOD (Just a Bunch of Disks): No redundancy. All drives combined into one big volume. One drive fails = data on that drive is lost. Never use JBOD for important data.
Important: RAID is NOT a backup. RAID protects against drive failure, but not against accidental deletion, ransomware, fire, or theft. Always maintain a separate backup (external drive or cloud) alongside your NAS.
CPU Requirements by Use Case
| Use Case | CPU Needed | Recommended NAS |
|---|---|---|
| File storage + backup | ARM or Intel (any) | QNAP TS-233 ($169) |
| Photo management (AI) | Intel preferred | Synology DS224+ ($299) |
| Plex (Direct Play) | ARM or Intel (any) | Asustor AS3304T v2 ($269) |
| Plex (Transcoding) | Intel with Quick Sync | QNAP TS-464 ($449) |
| Docker containers | Intel x86 required | UGREEN DXP2800 ($296) |
| Virtual machines | Intel + 8GB+ RAM | QNAP TS-464 ($449) |
| Surveillance (4+ cameras) | Intel + 4GB+ RAM | Synology DS925+ ($620) |
Total Cost of Ownership: NAS + Drives
The NAS enclosure is only part of the cost. Here's what a complete setup actually costs:
| Setup | NAS | Drives | Total | Usable Storage |
|---|---|---|---|---|
| Budget 2-bay | QNAP TS-233 ($169) | 2 x 4TB WD Red ($180) | $349 | 4TB (RAID 1) |
| Mid-range 2-bay | Synology DS224+ ($299) | 2 x 8TB Seagate IronWolf ($320) | $619 | 8TB (RAID 1) |
| Mid-range 4-bay | QNAP TS-464 ($449) | 4 x 8TB Seagate IronWolf ($640) | $1,089 | 24TB (RAID 5) |
| Power user 4-bay | Synology DS925+ ($620) | 4 x 16TB WD Red Pro ($1,040) | $1,660 | 48TB (RAID 5) |
NAS-rated drives are strongly recommended. Standard desktop drives (WD Blue, Seagate Barracuda) aren't designed for 24/7 operation and have higher failure rates in NAS enclosures. WD Red Plus, Seagate IronWolf, and Toshiba N300 are the three most popular NAS drive lines, typically priced at $20-$25 per TB.
What You'll Need to Get Started
- NAS enclosure — Choose based on bay count, CPU, and software ecosystem (see recommendations above)
- NAS-rated hard drives — WD Red Plus or Seagate IronWolf are the go-to choices. Buy identical drives for each bay. Budget $80-$260 per drive depending on capacity (4TB-16TB)
- Ethernet cable (Cat 5e or better) — Connect NAS to your router. Cat 6 recommended if your NAS supports 2.5GbE
- UPS (Uninterruptible Power Supply) — Optional but highly recommended. A power outage during a write operation can corrupt your array. Budget $50-$100 for a basic UPS (APC Back-UPS 600VA covers most 2-4 bay NAS units)
- Router with available Ethernet port — Any home router works. For 2.5GbE NAS devices, a 2.5GbE switch ($30-$50) maximizes transfer speeds
- External USB drive for 3-2-1 backup — NAS protects against drive failure; an external backup protects against everything else (ransomware, fire, theft). Budget $60-$120 for a 4-8TB USB drive
Total startup cost (budget): $349-$500 for a complete, redundant personal cloud that replaces $10+/month in cloud subscriptions.
NAS Use Cases: What Can You Actually Do?
Plex Media Server
Stream your movie and TV collection to any device in your house (and remotely). A NAS with Intel Quick Sync (DS224+, TS-464, F2-223) handles 4K-to-1080p transcoding for devices that don't support 4K natively. Direct Play (ARM NAS devices) works perfectly if your TV or streaming device plays 4K natively.
Photo Backup & Management
Replace Google Photos with Synology Photos, QNAP QuMagie, or Immich (Docker). AI-powered face recognition, automatic organization, and mobile app backup — with no storage limits and complete privacy. Your family photos stay on your hardware, not someone else's servers.
Surveillance & Security Cameras
Most NAS devices support IP camera recording (Synology Surveillance Station, QNAP QVR Pro). Record 24/7 footage from your security cameras to your NAS instead of paying monthly cloud recording fees ($3-$10/camera/month). A 4-bay NAS with 4 cameras recording continuously stores roughly 30 days of footage on 8TB of storage.
Time Machine Backup (Mac)
Every Synology, QNAP, and ASUSTOR NAS supports Apple Time Machine over the network. Back up your Mac automatically over WiFi without plugging in a USB drive. Set it once and every Mac in your household backs up hourly.
Centralized File Sharing
One shared folder accessible from every computer, phone, and tablet in your home. No more emailing files to yourself or juggling USB drives. Family documents, school projects, work files — all in one place with user permissions.
Frequently Asked Questions
What is a NAS and do I need one?
A NAS (Network Attached Storage) is a dedicated storage device connected to your home network that functions as a personal cloud. You need one if you have more than 1TB of photos, videos, or documents; want to stop paying cloud storage subscriptions; need a Plex media server; or want complete control over your data privacy. For users storing under 500GB with no media server needs, cloud storage may be more practical.
How much electricity does a NAS use?
A 2-bay NAS consumes 15-25 watts during operation and 5-8 watts in hibernation. Running 24/7, that costs approximately $25-$40 annually at average US electricity rates ($0.14/kWh). A 4-bay NAS consumes 30-40 watts, costing $40-$55 annually. By comparison, a desktop PC running as a server consumes 150-300 watts — 5-10x more.
Can I access my NAS remotely from anywhere?
Yes. Synology QuickConnect, QNAP myQNAPcloud, and ASUSTOR EZ-Connect provide secure remote access without opening router ports. Connect from your phone, laptop, or any browser worldwide. For maximum security, set up WireGuard or OpenVPN directly on your NAS.
Is RAID the same as backup?
No. RAID protects against hard drive failure but does NOT protect against accidental deletion, ransomware, fire, flood, or theft. Follow the 3-2-1 rule: 3 copies of your data, on 2 different media types, with 1 copy offsite (cloud or remote location). Your NAS is copy #1, not your only copy.
Which NAS is best for Plex?
For hardware transcoding, choose an Intel-based NAS: QNAP TS-464 (best performance, 3-4 streams), Synology DS224+ (best software, 2-3 streams), or TerraMaster F2-223 (best budget, 1-2 streams). For Direct Play only (4K TV or Apple TV 4K), any NAS works — even the $169 QNAP TS-233.
How long do NAS drives last?
NAS-rated drives (WD Red, Seagate IronWolf) typically last 3-5 years with 24/7 operation. Backblaze's published drive statistics show annualized failure rates of 1-3%. RAID protection ensures a single drive failure doesn't cause data loss, giving you time to replace the failed drive.
Can I use regular desktop hard drives in a NAS?
Technically yes, but not recommended. Desktop drives aren't designed for 24/7 operation, have higher vibration sensitivity in multi-bay enclosures, and lack RAID firmware optimizations. NAS-rated drives cost 10-20% more but are engineered for continuous operation and vibration tolerance.
What happens if my NAS fails completely?
If the NAS enclosure fails (motherboard, power supply), your data is still on the drives. You can install them in a replacement NAS of the same brand and typically recover the RAID array intact. Synology, QNAP, and ASUSTOR all support drive migration between compatible models.
Conclusion: Our Top Pick for 2026
After comparing hardware specs, software ecosystems, transcoding performance, networking speeds, and total cost of ownership, the Synology DS224+ is the best NAS for most home users in 2026.
The QNAP TS-464 has better specs on paper. The UGREEN DXP2800 has newer hardware at a lower price. The TerraMaster F2-223 offers more for less money. But no other NAS matches Synology's combination of software quality, ease of use, app ecosystem, community support, and long-term reliability that makes the DS224+ the safest recommendation for someone buying their first NAS.
DSM 7.2 is the reason. It turns a complex storage appliance into something anyone can use — set up Synology Photos in 5 minutes, configure automated backups in 10, and have a Plex media server running before lunch. No other NAS manufacturer's software comes close to this level of polish.
Here's the decision simplified:
- Most home users? -> Synology DS224+ — best software, $299
- Power user / many drives? -> Synology DS925+ — 4-bay, 2.5GbE, $620
- Plex media server? -> QNAP TS-464 — best transcoding, $449
- Best hardware per dollar? -> UGREEN DXP2800 — N100 + 8GB DDR5, $296
- 4-bay on a budget? -> Asustor AS3304T v2 — 4 bays + 2.5GbE, $269
- Cheapest Intel NAS? -> TerraMaster F2-223 — dual 2.5GbE, $200
- Absolute budget? -> QNAP TS-233 — just works, $169
A NAS is one of the few tech purchases that saves you money over time. Every month you pay $10+ for cloud storage is a month you could be building equity in hardware you own. Your photos, your videos, your documents — stored on your drives, in your home, under your control. No subscription fees, no privacy compromises, no storage limits.
