KitGuru reports discounts on BIWIN NVMe and SATA SSDs, plus USB flash drives, for Amazon UK listings during October 2026. Its reported reductions range from around 10% to around 28% on SSDs, but they are estimates—not verified checkout prices or proof of a historical low. Amazon calls the October 6–7 event Prime Big Deal Days; its 2026 Prime Day took place earlier, June 23–26.
Which BIWIN drives are reported on offer?
KitGuru’s October 2026 report separates offers running October 1–14 from those listed for the October 6–7 event window. Percentages below are approximate source-reported discounts, not independently verified prices.

The report supplies percentages, but not the live checkout price, a price-history comparison, or enough performance testing to rank these models by speed. A larger discount also does not necessarily mean the best value: compare the current listing price for the capacity and drive type you need.
#1 Best Overall
- 【7450MB/s・Amazing Speed】Maximum read speed of 7450MB/s and maximum write speed of 6500MB/s (random read/ write speed of up to 1000K IOPS) realises the workflow of high-performance desktop PCs and notebook PCs. Ideal for power users who are looking for market-leading speeds.
- 【PCIe Gen4×4 for Superior Performance】Biwin NV7400 M.2 SSD utilizes the latest PCIe Gen 4x4 and 3D TLC NAND, choosing high-quality premium NAND flash chosen through our automated selection. Capacities of up to 4 TB are available, providing ample storage space and eliminating the anxiety of insufficient storage.
- 【PMIC Power Management & Graphite Heat Sink】NV7400 M.2 SSD adopts a composite power supply IC (PMIC), which improves power saving and energy saving performance by increasing the efficiency of power distribution, and effectively extends the durability of the SSD. Moreover, it is equipped with a 0.5mm graphene aluminium heat sink to prevent overheating with excellent heat dissipation performance and maintain stable top performance.
- 【Enhanced System Stability】The NV7400 delivers stable performance for demanding applications. Enhanced by Host Memory Buffer (HMB) technology, it ensures stable operation even under heavy workloads. The integration of Smart Cache optimizes data retrieval, while Zip data compression maximizes storage efficiency.
- 【Free Biwin Intelligence Software】Biwin Intelligence is multifunctional management software, designed to support Biwin consumer-brand storage products. For a more convenient and more secure storage experience, this software helps users manage their drives with features like performance test, data migration, firmware update, and more.
The listed products cover different uses and interfaces: NVMe and SATA SSDs are internal storage options, while MS100 and UD150 are USB flash drives. The report does not provide benchmark evidence for comparing the performance of individual SSD models.
Why this October event is not Prime Day
Amazon’s event naming distinguishes the two 2026 promotions. Amazon says Prime Day ran June 23–26; the October 6–7 promotion is Prime Big Deal Days. KitGuru’s report uses “Prime Day” in its headline, but Prime Big Deal Days is the accurate name for the October event.
