Model F4-424 Pro
Who the TerraMaster F4-424 Pro is for
Fill all 4 bays in RAID 5 and you keep 75% of the raw space, losing one drive's worth to parity. It's an Intel Core i3-N305 in there, for the record. RAM goes to 32 GB.
Watch out for
Networking tops out at 2 × 2.5GbE. There's no 10GbE and no PCIe slot to add it later.
The two M.2 slots take NVMe drives for a cache or a small fast pool.
Usable space with 4 matching drives
These are decimal TB, the way drive boxes count them, and Windows will show roughly 9% less. Got a mix of sizes? Put your own drives in the calculator and it'll work out the layers.
