Model TS-473A-8G
Who the QNAP TS-473A is for
Run RAID 5 across the 4 bays and 75% of the raw space is yours to fill. (Still not a backup, though.) It's an AMD Ryzen Embedded V1500B in there, for the record. RAM goes up to 64 GB (ECC included), which is plenty for a couple of VMs as well as the usual containers.
No 10GbE out of the box, but the PCIe slots will take a card 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.
| Each drive | RAID 5 (1 parity) | RAID 6 (2 parity) |
|---|---|---|
| 4 TB × 4 | 12 TB ≈ 10.9 TiB | 8 TB ≈ 7.3 TiB |
| 8 TB × 4 | 24 TB ≈ 21.8 TiB | 16 TB ≈ 14.6 TiB |
| 12 TB × 4 | 36 TB ≈ 32.7 TiB | 24 TB ≈ 21.8 TiB |
| 16 TB × 4 | 48 TB ≈ 43.7 TiB | 32 TB ≈ 29.1 TiB |
| 20 TB × 4 | 60 TB ≈ 54.6 TiB | 40 TB ≈ 36.4 TiB |
| 24 TB × 4 | 72 TB ≈ 65.5 TiB | 48 TB ≈ 43.7 TiB |
