What is genuinely cheap here today: the SanDisk Desk Drive SSD 8TB at £659.99 (£82.50/TB), at or below the lowest price we have recorded for it (£659.99 on 20 Sept 2026). All 40 products in the table are at or near their own recorded low.
SATA SSDs suit NAS units without M.2 slots, either as a fast volume for apps and virtual machines or as a read cache in a drive bay. The WD Red SA500 is built for NAS endurance, while the Samsung 870 EVO and Crucial MX500 are sound consumer choices for light use. SSD prices rose through 2026, so the verdict column matters more here than the badge.

Verdicts compare today's price with the lowest price we have recorded for the same listing. Amazon was is Amazon's own reference price. Prices can change after our check; the price on Amazon.co.uk at checkout applies.
Is it really a deal?
SATA SSD prices climbed through the year, so we only call one a deal when today's figure is at or close to the lowest we logged for it. 40 of 55 products we have re-priced are at or within 3% of their lowest recorded price; the SanDisk Desk Drive SSD 8TB is equal to our recorded low of £659.99, logged on 20 Sept 2026. 15 sit above what we have recorded, such as the TERRAMASTER F4 SSD NAS 32TB, now 33% above our recorded low; those are in the collapsed list at the bottom.
Prices we checked and would not pay (15)
These are above the lowest price we have recorded for the same listing, or above their 30-day median. They are here so you can see we checked them.

Frequently asked questions
Do I need a NAS-specific SATA SSD?
For a cache that writes constantly, a NAS-rated drive like the Red SA500 lasts longer. For an app volume with light writes, a good consumer SSD is fine.
Should I use SATA SSDs as a cache or a volume?
On most home units a small SSD volume for Docker, apps and the system brings more benefit than a cache. Caching helps busy multi-user setups most.
Will a SATA SSD fit in a 3.5-inch bay?
Most NAS trays have screw holes for 2.5-inch drives. Check your model's tray; some need an adaptor bracket.
Is it worth buying SATA SSDs now?
Only if the verdict says real or near low. Flash prices have trended up this year, so waiting for a dip is a fair bet if the price is above our log.
