Best home NAS for media, at a glance
Wirecutter's top pick for the 2-bay home NAS in 2026 is the Synology DiskStation DS225+ at $365, with the 4-bay DS425+ as the upgrade pick. The October 2025 reversal of Synology's third-party-drive policy restored WD Red Plus and Seagate IronWolf as first-class options, dropping the cost of a populated home NAS by roughly 20 to 30 percent versus the 2024 Synology-only world. For a household backing up laptops and phones with a modest media library, the right pick in 2026 is the DS225+ plus two 8 TB WD Red Plus drives, totaling $765. For a household with a serious media library, the DS425+ plus four 16 TB IronWolf drives in RAID 5 gives 48 TB of usable capacity.
| Home profile | Chassis pick | Drive pick | Approx total |
|---|---|---|---|
| 2-3 devices, modest photo library | Synology DS225+ (2-bay) | 2 × 8 TB WD Red Plus | $765 |
| 4-6 devices, mid-size media library | Synology DS425+ (4-bay) | 4 × 12 TB WD Red Plus (RAID 5) | $1,295 |
| Heavy media + video editing workstation | Synology DS425+ (4-bay) | 4 × 16 TB Seagate IronWolf (RAID 5) | $1,835 |
| Tight budget, single-user | QNAP TS-216G (2-bay) | 2 × 4 TB Toshiba N300 | $430 |
What a home NAS actually does in 2026
A home network-attached storage (NAS) device is a small always-on computer on the local network that backs up laptops and phones, centralizes media libraries, and serves files to TVs and tablets. Wirecutter defines it as "a shared computer that backs up the data from and serves those files back to your phones and PCs."[1] For most households, the practical case is one of four jobs, in roughly descending order of how often people buy one for each.
Auto-backup of laptops and phones. A NAS sits on the home network and continuously backs up every Mac, Windows PC, and phone that connects to the home Wi-Fi. Without one, backups happen only when someone plugs in an external drive, which in most homes means never.
Centralized photo and video library. Synology Photos, QNAP QuMagie, and the open-source Immich all serve a phone-photo library to every device on the home network without the per-month fees of iCloud or Google Photos. The trade-off is that the storage is local; if the house burns down, the library is gone.
Self-hosted media. Plex, Jellyfin, and Emby all run on a NAS and stream to TVs, phones, and tablets on the home network. For a household with a large ripped-movie collection or 4K home-video library, a NAS is the right host.
Local file server. A NAS serves as a Dropbox or Google Drive alternative for households that want files on the local network without monthly cloud fees. This is the original NAS use case and remains the most flexible.
The October 2025 Synology policy reversal
Prior to October 2025, Synology took the unusual step of deeming third-party NAS-class drives "incompatible" with its consumer and prosumer chassis, and steering customers toward Synology-branded drives. Synology-branded drives were Toshiba or Seagate mechanisms sold at a markup of around 20 percent over the equivalent third-party NAS drive.[1]
The October 2025 DSM 7.3 release reversed this. Synology-branded drives remain supported and are still the only drives that trigger Synology's own health-monitoring and warranty integration, but devices like the WD Red Plus, Seagate IronWolf, and Toshiba N300 now work out of the box with no warnings and no blocked storage pools.[1] The remaining restriction is on M.2 NVMe SSDs in the cache slots of certain 2025-and-later boxes, which still require Synology-branded drives; for most home users populating spinning 3.5-inch bays, that restriction does not apply.
The dollar impact is concrete. A Synology-branded 8 TB NAS drive lists for roughly $260 as of mid-2026; the equivalent WD Red Plus 8 TB lists for roughly $200. For a 2-bay box populated with two drives, that is a $120 saving; for a 4-bay box, $240. Across a typical home NAS purchase in 2026, the policy reversal saves about $150 on average, and that money is better spent on a larger capacity per drive.
Pick the chassis first
The chassis decision is about CPU, RAM, bay count, and software ecosystem. Drive choice comes second.
The Synology DiskStation DS225+ is the right pick for most home users. Wirecutter's 2026 NAS roundup named it the top pick, citing the 2.5 GbE networking port and the ease of use of DSM software.[1] It is a 2-bay box with an Intel Celeron processor, two M.2 NVMe cache slots, and one 2.5 GbE Ethernet port. As of mid-2026 it lists for around $365 without drives.
The Synology DiskStation DS425+ is the upgrade pick for households that want more storage headroom. It is the same hardware as the DS225+ but in a 4-bay chassis. The extra bays let you run RAID 5 (which gives you three of four drives' worth of usable capacity rather than RAID 1's two-of-two) and add a fourth drive later if you outgrow the original pair. The price delta over the DS225+ is around $100 to $150.
The QNAP TS-216G is the budget pick at around $250 without drives. QNAP's QTS software is more configurable than Synology's DSM but has a steeper learning curve. If you want Plex transcoding performance on the cheap, the TS-216G has a more capable CPU than the equivalently priced Synology; if you want set-and-forget simplicity, the Synology chassis are better.
SSD-only NAS boxes (the Asustor Flashstor line, QNAP TBS-h464) are a different category. The same money buys roughly 8x more capacity with spinning drives; for media backup, that math does not favor SSD-only NAS.[1] SSD-only makes sense if the priority is raw throughput for video editing or a small set of fast files rather than a large media library.
RAID for home
The RAID level you pick determines usable capacity and redundancy. For home media backup, three options cover nearly every realistic case.
RAID 1 mirrors two drives. You write the same data to both, so a single drive failure doesn't lose data. Usable capacity is 50 percent of the raw drive capacity: two 8 TB drives in RAID 1 give you 8 TB of usable storage. RAID 1 is the right choice for a 2-bay NAS where simplicity matters and the total storage needed is moderate.
RAID 5 strips data across three or more drives with one drive's worth of parity. Usable capacity is total drive capacity minus one drive's worth: four 8 TB drives in RAID 5 give you 24 TB of usable storage. RAID 5 needs at least three drives to be meaningful, which means a 4-bay chassis. It is the right choice for larger media libraries on a 4-bay box.[2]
Synology Hybrid RAID (SHR) is Synology's proprietary equivalent. The benefit over RAID 5 is that SHR lets you mix drive sizes; the cost is that it is vendor-specific, so migrating to a non-Synology box later requires a data migration. For most home users who will stay on Synology hardware, SHR is the simpler choice.
RAID 0 and JBOD are both the wrong choice for backup. RAID 0 stripes data across drives with no redundancy; one drive failure loses everything. JBOD concatenates drives but also has no redundancy. Both defeat the entire reason to have a NAS.
Pick the drives
The 2026 NAS-class drive market splits cleanly into four families.
WD Red Plus uses conventional magnetic recording (CMR), which is the right recording technology for RAID arrays. WD Red Plus drives are 5400 RPM class (recent models run 5640 RPM with a small cache) and are available in capacities from 2 TB up to 14 TB. The 8 TB Red Plus is the most common sweet-spot pick for a 2-bay home NAS as of mid-2026, and the 12 TB and 14 TB are the picks for 4-bay configurations where RAID 5 capacity matters.[2]
Seagate IronWolf drives run at 7200 RPM in the smaller capacities and use CMR. IronWolf's edge over WD Red Plus is the higher maximum capacity (16 TB and 18 TB IronWolf drives exist) and the inclusion of IronWolf Health Management software, which monitors drive health and integrates with Synology and QNAP chassis. For a 4-bay home NAS where you want the most capacity in one box, IronWolf at 16 TB or 18 TB is the right pick.[2]
Toshiba N300 drives are the third NAS-class family. They use CMR and run at 7200 RPM. The N300 is positioned as a budget alternative to the WD Red Plus and Seagate IronWolf; reviews are largely positive and the price is typically a few percent below the equivalent WD Red Plus.
Synology-branded drives are now genuinely optional. They are Toshiba or Seagate mechanisms with a Synology firmware and a Synology warranty. The case to buy them used to be the official Synology support; the case against them now is the 20 percent price premium for the same underlying hardware.[3]
M.2 NVMe SSD caching is a separate decision that the 4-bay Synology boxes (DS425+ and similar) support. A small NVMe SSD in the cache slot accelerates random read/write operations, which is what you want if multiple users are accessing the NAS simultaneously. For a single-user home NAS, the cache slot can be left empty without a meaningful performance penalty.[3]
Cost per usable terabyte, across the realistic options
| Setup | Raw cap | Usable | Total | $/TB usable |
|---|---|---|---|---|
| DS225+ + 2 × 8 TB Red Plus (RAID 1) | 16 TB | 8 TB | $765 | $95.6 |
| DS425+ + 4 × 12 TB Red Plus (RAID 5) | 48 TB | 36 TB | $1,295 | $36.0 |
| DS425+ + 4 × 16 TB IronWolf (RAID 5) | 64 TB | 48 TB | $1,835 | $38.2 |
| DS425+ + 4 × 4 TB SSD (RAID 5) | 16 TB | 12 TB | $3,165 | $263.8 |
The cost-per-TB math is brutal for SSD-only NAS at home. The SSD option above costs nearly 7x per usable terabyte compared to the 4-bay HDD option. Wirecutter calls this out directly: "Each internal 4 TB SSD is approaching $700 as we write this guide, and for the same amount of money you can purchase 32 TB Seagate IronWolf Pro hard drives."[1]
What to skip
SSD-only NAS for media storage. The capacity-per-dollar is wrong.
Off-brand NAS (no major software ecosystem). Security patching cadence and ransomware resilience are real concerns. Synology, QNAP, Asustor, and TerraMaster all have established firmware update tracks.
RAID 0 or JBOD. Both defeat the redundancy that is the point of having a NAS.
My Cloud OS or other simplified platforms. These are file servers with a NAS label, not a NAS. The software is limited compared to Synology DSM or QNAP QTS.
Frequently asked questions
Do I really need a NAS if I use cloud backup?
Cloud backup and a NAS solve different problems. Cloud backup is off-site and survives local disasters (fire, flood, theft) but requires monthly fees and an internet connection to restore. A NAS is local, fast, and free to operate but does not survive local disasters without an off-site backup. The right answer for most households is both: NAS as the primary local backup, with a cloud backup of the NAS (Backblaze B2 is the common pick) for off-site redundancy.
Is Synology still worth it after the October 2025 drive policy reversal?
Yes. The reversal was a one-way concession in the buyer's favor. The Synology DSM software, the 2.5 GbE networking port on the 2026 chassis, and Synology's app ecosystem (Photos, Drive, Hyper Backup, Synology Office) remain the strongest home NAS software in 2026. The reversal only means you no longer have to buy Synology-branded drives to get full compatibility.
Can I mix drive sizes in RAID?
Standard RAID levels (1, 5, 6) do not support mixed drive sizes efficiently: in RAID 1 with a 4 TB and an 8 TB drive, you only get 4 TB of usable capacity because the larger drive is sized down to match the smaller one. Synology Hybrid RAID (SHR) does support mixed sizes and uses the full capacity of each drive. If you plan to mix sizes, use SHR.
How long do NAS drives last?
NAS-class drives are rated for 24/7 operation and typically last 5 to 8 years in home use. The drives include vibration sensors (WD Red Plus and Seagate IronWolf) that detect the rotational vibration of nearby drives in a multi-bay chassis and reduce seek errors. The failure mode is gradual rather than catastrophic; IronWolf Health Management and WD's equivalent monitor drive health and predict failures before they happen.
Do I need SSD caching?
For a single-user or two-user home NAS, no. SSD caching helps when many users access the NAS simultaneously, which is uncommon at home. If you have a 4-bay chassis, the M.2 NVMe slot can be left empty or populated with a small NVMe drive for caching later. It is a "nice to have" upgrade, not a required one.
The bottom line
Pick the chassis first. The Synology DS225+ is the right pick for most home users, the Synology DS425+ is the upgrade pick for larger media libraries, and the QNAP TS-216G is the budget pick. Skip SSD-only NAS for media.
Pick the drives second. With Synology's October 2025 policy reversal, third-party NAS-class drives are first-class citizens. WD Red Plus is the default for most homes, Seagate IronWolf is the right pick when you need higher capacities, Toshiba N300 is the budget alternative, and Synology-branded drives are now an optional 20 percent premium rather than a required purchase.
The two-step decision costs roughly $765 for the budget 2-bay setup or $1,835 for the 4-bay RAID 5 setup, both as of mid-2026. Either is a sound investment for a household that wants their data and media under local control, with cloud backup as the off-site hedge.
