NVMe SSD Cache Deals – Prime Big Deal Days 2026
NVMe is where this event's real cuts are. Our observed history for these listings goes back to mid-September, and many 2TB and 4TB drives are below anything we recorded before today. In a NAS, an M.2 drive is used as read cache or as a fast storage pool, so the table below is followed by the NAS models whose M.2 slots each drive fits.

Verdicts: Our tracked low is at or below the lowest price we recorded before today; within 3% is close to it; cut vs list only is below Amazon's reference price but above our low; no history yet means we make no claim. The 90-day line shades the event days. Was prices are Amazon's reference prices.

Is it really a deal?
The Biwin NV7400 4TB at $415.99 is our tracked low: the lowest we recorded was $489.99 on Sep 29. Of 217 rows, 157 are at or near our low, 7 are cut only against Amazon's list price, 48 cost more than usual, and 5 have no history yet. These verdicts come from each listing's own daily price history, so a real low here means the drive is cheaper than on any day we recorded. Hard drive prices have risen through 2026 on AI datacenter demand (why hard drives cost more in 2026), so a price that only matches our low is a better outcome than in an ordinary year.

Frequently asked questions
Do I need NVMe cache in a home NAS?
For media and backups, no. Cache helps with many small random reads, such as photo libraries and virtual machines. A UGREEN or QNAP with M.2 slots can also use the drives as a fast storage pool.
Which NAS models take these drives?
Any NAS with M.2 2280 NVMe slots, listed under the table. Synology's 2025 Plus models only allow Synology drives for storage pools; third-party drives work as cache.
Is a PCIe 5.0 drive worth it in a NAS?
No. NAS M.2 slots are usually PCIe 3.0 or 4.0 with one or two lanes, and the network is the bottleneck. A PCIe 4.0 TLC drive is plenty.
Is the Samsung 990 PRO price real?
Check its verdict. Samsung's list price is far above its usual street price, so a large cut against list is normal; our verdict compares it with the price we actually recorded.
