4TB SSD Deals – Prime Big Deal Days 2026

A 4TB SSD replaces a game library's worth of hard drive space, and at this capacity price per terabyte often beats 2TB. The 990 EVO Plus 4TB and WD Blue SN5000 4TB are the reference points, but the ranking is by verdict and price per terabyte across every tracked 4TB NVMe and SATA drive.

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 64 rows, 27 are at or near our low, 1 are cut only against Amazon's list price, 8 cost more than usual, and 28 have no history yet. 4TB NVMe verdicts come from each listing's own daily price record; a 4TB drive is compared only with its own history, never with a 2TB drive. 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

Is one 4TB SSD better than two 2TB SSDs?

Usually. It uses one slot, often costs less per terabyte and leaves room to add another drive later. Two 2TB drives only win when they are much cheaper together.

Is QLC flash a problem at 4TB?

For game storage, rarely. Large sustained writes slow down once the cache fills, which matters for video editing and heavy downloads more than for loading games.

Which 4TB SSD fits a PS5?

Any PCIe 4.0 M.2 2280 drive with a heatsink, or with a low-profile heatsink added. The PS5 accepts up to 8TB.

Will 4TB SSDs drop again on Black Friday?

Possibly to the same level. Rows at our tracked low today are as cheap as we have recorded; flash prices were climbing before the event.
