6 & 8-Bay NAS Deals UK – Prime Big Deal Days 2026
Prices checked
Prime Big Deal Days runs 6 to 7 October 2026 for Prime members, with new Today's Big Deals three times a day. We re-check these prices at 08:00, 16:00 and 21:00 UK time.

What is genuinely cheap here today: the UGREEN DXP8800 Plus at £999.99 (£125.00/bay), at or below the lowest price we have recorded for it (£1,189.99 on 22 Jul 2026). 2 of 3 products in the table are at or near their own recorded low; the rest only beat Amazon's reference price or are new to our tracker.
Five to eight bays is for people who already know they need a lot of storage: large media libraries, video work or a small office. The DXP8800 Plus brings ten CPU cores and twin 10GbE, the DS1525+ adds Synology's software, and the F8 SSD Plus swaps disks for eight M.2 slots. With this many drives, the enclosure is often the smaller part of the bill, so the fill table matters most here.

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?
On large units the drives dominate the bill, so we check the enclosure against its own logged prices and then the cost of filling it. 2 of 5 products we have re-priced are at or within 3% of their lowest recorded price; the UGREEN DXP8800 Plus is 16% under our recorded low of £1,189.99, logged on 22 Jul 2026. 2 sit above what we have recorded, such as the Synology DS1825+, now 10% above our recorded low; those are in the collapsed list at the bottom. 1 is too new to our tracker to measure, so for it we show Amazon's own was-price as Amazon's claim, and the fill-cost table below is the better guide to value.
Cheapest full build for each unit
For each enclosure on this page, the drive size that gives the lowest cost per usable terabyte at today's prices.

Usable space uses the same maths as our RAID calculator, after about 9% formatting overhead. Drive prices are the cheapest in-stock NAS-rated CMR drive at each size when we last checked. Buy Now adds the enclosure and all the drives to your Amazon.co.uk basket in one go.

Frequently asked questions
Is an eight-bay NAS overkill for home use?
For most homes, yes. It earns its place if you keep large video archives or want RAID 6 with room to grow, since each extra bay bought now is cheaper than a second NAS later.
How loud is an eight-bay NAS full of drives?
Eight spinning drives are audible in a quiet room, especially enterprise models like Exos. Put it in a cupboard or office with airflow rather than a living room.
Does the DS1525+ count as a six-bay?
It is a five-bay that can grow with Synology expansion units. We group it here because buyers comparing it are usually also weighing six and eight-bay options.
What RAID level suits eight large drives?
RAID 6 or SHR-2. Rebuilding one 20TB drive takes long enough that a second failure during rebuild is a real risk, and two-disk protection covers it.
