Best drives for the TerraMaster F4-425 in Canada
By Devin Chua · Data checked by Owen Nakamura · Updated · Prices checked For the TerraMaster F4-425 fit CMR NAS drives like WD Red Pro or Seagate IronWolf Pro across all 4 bays up to 120 TB raw. TerraMaster locks no drive brand on the F4-425; its compatibility list is guidance, not a gate. At 4 × 8 TB the F4-425 keeps 21.83 TiB usable in TRAID, about CA$2,288 in drives. Since its Intel N5095 (4 cores, 2.0 GHz) hardware-transcodes Plex through Intel Quick Sync and runs a stack of containers, with a light VM or two as the ceiling, an ordinary CMR drive already saturates the F4-425's link.

What sets the F4-425 apart
The only alternative to Synology with a genuine SHR counterpart: TRAID uses mixed drive sizes, TRAID+ matches SHR-2 with double fault tolerance. If you have a stack of mismatched drives, you lose less here than with UGREEN or QNAP.
Who the F4-425 is for
The F4-425's Intel N5095 (4 cores, 2.0 GHz) is the home-NAS sweet spot. Its integrated graphics hardware-transcode Plex (4K HEVC included, through Intel Quick Sync) and it runs a stack of Docker containers without complaint; heavy virtualization is the one thing it leaves to bigger machines. With 4 GB stock and up to 16 GB, the F4-425 suits a household that wants its media server and its drives in one quiet box.
How the F4-425's network shapes the drive choice
The F4-425 runs 1 × 2.5GbE. Two-and-a-half gigabit is about 280 MB/s (almost exactly what a modern high-capacity NAS drive reads off its outer tracks) so the F4-425 sits in the sweet spot where an ordinary CMR drive saturates the link and a Pro model buys nothing on speed. Drives under about 8 TB fall short here for lack of areal density; from 8 TB up, a standard IronWolf or WD Red Plus is the right call on the F4-425.
Drive policy: TerraMaster locks no drive brand on the F4-425; its compatibility list is guidance, not a gate. The F4-425’s full compatibility rules.
Keep calculating
To see how much capacity is left after parity, the F4-425 capacity calculator is preset to its 4 bays and RAID types. For the F4-425, the wider basics of choosing a drive are in the buying guides, and CMR versus SMR explains why SMR drives do not belong in a RAID array. Wondering what the F4-425 can actually do: Plex, Immich, Docker, VMs? See what the F4-425 can run.
Frequently asked questions
Can I put third-party drives in the F4-425?
Yes. TerraMaster locks no drive brand on the F4-425; its compatibility list is guidance, not a gate.
Which drives fit the F4-425?
The F4-425 takes any 3.5-inch SATA and 2.5-inch SATA SSD drive; use a CMR NAS family rated for 24/7 duty such as IronWolf, WD Red Plus or Toshiba N300. On its 1 × 2.5GbE, a standard CMR drive is already fast enough for the F4-425.
How much capacity is usable in the F4-425?
In the F4-425, 4 × 8 TB in TRAID gives about 21.83 TiB usable and survives 1 drive failing; the balance is parity.
Can the F4-425 run Plex with hardware transcoding?
Yes. The F4-425's Intel N5095 (4 cores, 2.0 GHz) includes Intel Quick Sync, which hardware-transcodes Plex including 4K HEVC, so it handles several streams at once without loading the CPU.
Is a Pro drive worth it in the F4-425?
Marginal. The F4-425's 1 × 2.5GbE sits right where a standard CMR drive already saturates the link, so a Pro drive mainly buys warranty, not speed.
