Quick answer

A 2.5-inch SATA SSD goes in an ordinary drive bay, so it works in every NAS here that has bays: no M.2 slot, lane width or heatsink to check. The one NAS-branded SATA line with a maker's endurance figure recorded here is the WD Red SA500, rated from 350 TBW at 500GB to 2,500 TBW at 4TB, with a five-year limited warranty. SATA caps the speed at about 560 MB/s, which is still more than a 2.5GbE port carries.

What NAS makers say about SATA SSDs

MakerRule
UGREENSATA SSDs are supported; a tested model is recommended, and SSDs with heatsinks are not supported
Synology, 2025 modelsThird-party 2.5-inch SATA SSDs can build storage pools from DSM 7.3; the compatibility list itself names 19 Synology SAT drives
QNAPLists 2.5-inch SATA SSDs as a compatible drive type; tested models are on its compatibility list
TerraMasterLists 2.5-inch SATA SSDs as a compatible drive type
AsustorLists 2.5-inch SATA SSDs as a compatible drive type

Two details in WD's sheet

The SA500 name covers two shapes. Model numbers ending in A are 2.5-inch drives for a bay; those ending in B are M.2 2280 SATA sticks, which will not work in an NVMe-only M.2 slot. The tables on this page are 2.5-inch drives.

The 2TB size exists in both shapes at the same 1,300 TBW, and 4TB only as a 2.5-inch drive. WD notes that the 2TB and 4TB 2.5-inch figures are measured on a different workload from the smaller ones, so compare within a size class.

Where the figures come from

Western Digital's WD Red product briefs, read on October 12, 2026. Each figure is the one printed beside the model number. Other makers' cache drives are not in the table because their endurance figures have not been read into this site's record.

Frequently asked questions

Can I put a SATA SSD in a NAS drive bay?

Yes, in a 2.5-inch SATA bay or a 3.5-inch bay that takes 2.5-inch drives, which every maker here lists as a compatible drive type.

What is the endurance of the WD Red SA500?

350 TBW at 500GB, 600 TBW at 1TB, 1,300 TBW at 2TB, 2,500 TBW at 4TB for the 2.5-inch models, by WD's product brief.

Is a SATA SSD fast enough for a NAS?

For the network, yes: WD lists the SA500 at up to 560 MB/s reading, and a 2.5GbE port carries roughly half that.
