Quick answer

For the F4-425 Plus, fit SATA SSDs like the Ediloca ES580E 4TB, around £267.99 at last check, if you want an all-flash pool that actually uses this NAS's Intel N150 grunt and 2.5GbE ports. This box has 4 SATA bays plus 3 separate NVMe slots for cache, so you are not forced to choose between speed and capacity, you can run SATA SSDs in the main bays and still keep NVMe free for caching. With 16GB of RAM and hardware transcode on board, an all-SSD array here is genuinely useful for Plex libraries, VM hosting or a busy multi-user SMB share, not just a spec-sheet flex.

Best SATA SSDs for the F4-425 Plus

Picked for capacity-per-pound and reliability in a 24/7 NAS bay, not for the fastest sequential number on the box.

Which should you pick

Choose the 2TB Ediloca if

  • You are building a RAID1 or RAID10 pool for VMs, databases or a busy Plex library and want the lowest entry cost
  • You only need a couple of terabytes of fast storage and will keep bulk media on separate spinning disks
  • You are testing an all-SSD pool for the first time and do not want to commit four bays of budget at once

Choose the 4TB Fikwot FX815 if

  • You are filling all 4 bays with SSDs in RAID5 or RAID6 for a genuinely fast, capacious all-flash NAS
  • You run heavy multi-stream transcoding or several concurrent SMB users and want consistent sustained write performance
  • You want the fastest rated speeds in this line-up (560MB/s) and are happy to pay a small premium per TB for the SLC cache

Why SATA SSDs make sense in this specific NAS

The F4-425 Plus pairs an Intel N150 quad-core CPU with 16GB of DDR5 RAM and hardware transcode support, so it has the horsepower to push real throughput out of an all-SSD array rather than bottlenecking on the CPU first. With 2x 5GbE network ports, a RAID5 pool of four SATA SSDs can genuinely saturate one or both links for large file transfers, something a spinning-disk RAID5 array on this chassis would struggle to match consistently.

Because this model has three separate M.2 NVMe slots dedicated to cache or storage pools, you are not sacrificing anything by putting SSDs in the four main SATA bays. NVMe can handle read/write caching or a separate fast pool for VMs, while the SATA bays give you the bulk of your usable capacity in RAID5, RAID6 or RAID10. Third-party drive support is open on this unit, so none of the picks above trigger compatibility warnings or reduced functionality, unlike some NAS brands that lock features behind their own-branded drives.

Worth noting: TerraMaster's RAID options here are Basic, JBOD, RAID0, RAID1, RAID5, RAID6 and RAID10, there is no SHR-style flexible RAID. That means if you mix SSD capacities across bays, you lose the excess above the smallest drive in most RAID levels, so buying matched capacities across all four bays (as in the picks above) is the sensible approach rather than mixing a 2TB and a 4TB in the same array.

One honest caveat

None of the SSDs listed here are enterprise or NAS-rated drives with power-loss protection, they are consumer 2.5" SATA SSDs. That is fine for a home or small-office NAS running Plex, backups and general file sharing, but if you are running write-heavy database workloads or want maximum endurance for 24/7 sustained writes, budget for a step up to enterprise-class SATA SSDs later. For most F4-425 Plus users, though, these drives will comfortably outlast a typical 3 to 5 year NAS refresh cycle.

Frequently asked questions

Can the F4-425 Plus run all four bays as SATA SSDs and still use the NVMe slots?

Yes. The 4 SATA bays and the 3 NVMe slots are entirely separate on this model, so you can build a SATA SSD storage pool in the main bays and still fit NVMe drives for caching or a secondary fast pool, without one competing with the other.

Do I need matching SSD capacities across all four bays?

For RAID5, RAID6 or RAID10 on this model, yes, effectively. TerraMaster's supported RAID levels here do not include SHR, so mixing capacities means the array is capped to the smallest drive's size and you lose the extra space on larger drives. Buy four of the same capacity if you want maximum usable storage.

Will an all-SSD RAID5 array actually saturate the 5GbE ports?

It is realistic. With four SATA SSDs in RAID5 and the Intel N150 handling the parity calculations, sustained transfers can push close to 5GbE line speed for large sequential files, something a four-bay hard disk RAID5 array typically cannot sustain on this chassis.

Is hardware transcoding affected by using SSDs instead of hard disks?

Transcoding itself is handled by the Intel N150's hardware encoder regardless of drive type, so SSDs will not speed up transcode performance directly. Where SSDs help is with multiple simultaneous Plex or Jellyfin streams reading from the array at once, since SSDs handle concurrent random reads far better than spinning disks.

Are these consumer SSDs safe for 24/7 NAS use in the F4-425 Plus?

For typical home and small-office workloads, yes, they are designed for continuous desktop and light server use. They lack the power-loss protection of enterprise NAS drives, so if you are running constant heavy database writes, consider that a future upgrade path rather than a reason to avoid SSDs now.

Does third-party SSD support affect the warranty on the F4-425 Plus?

No. TerraMaster's third-party drive policy on this model is open, meaning any compatible SATA SSD works without locking out features or triggering compatibility warnings, unlike some competing NAS brands that restrict certain functions to their own-branded drives.
