KitGuru reports discounts across BIWIN NVMe and SATA SSDs and USB flash drives for Amazon UK listings during October 2026. Its reported SSD reductions range from around 10% to around 28%, but these are approximate discounts—not verified checkout prices or evidence of historical lows. Amazon calls the October 6–7 promotion Prime Big Deal Days; its 2026 Prime Day took place June 23–26.

What does “Prime Day” mean for these offers?
The October promotion is Amazon Prime Big Deal Days, scheduled for October 6–7, 2026. Amazon’s official event page distinguishes it from Prime Day, which ran June 23–26, 2026. KitGuru’s headline calls the October promotion “Prime Day,” but Prime Big Deal Days is the accurate name for that event.

What to check before buying
- Confirm the live listing. KitGuru links to Amazon UK listings. Check the current price, stock, seller and delivery terms on the product page; the report does not establish what a shopper will see at checkout.
- Match the type of storage to your device. The reported selection includes NVMe SSDs, SATA SSDs and USB flash drives. These are different product types, so compare only options compatible with your computer or intended use.
- Compare capacities and actual prices. The discount percentage alone does not show which drive is the best value; compare the live price for the capacity you need.
- Do not infer performance rankings. KitGuru’s report does not supply benchmark results, so it cannot establish which listed model is fastest.
The report gives no price-history comparison or independent product testing. It therefore does not establish that any offer is a historical low, or that the approximate savings will be available to every shopper.
