WD-Black's SN8100 2TB Gen 5 SSD hits a blazing-fast 14,900MB/s read speeds — and it's down to $400

If you're building or upgrading a PCIe Gen 5 system, this is one of the fastest consumer drives you can buy. Right now, the 2TB WD_Black SN8100 is $400 (was $440) at Amazon, a $40 savings on a drive that tops out at nearly 15,000 MB/s.

That speed matters most for large sequential transfers — moving big game installs, video files, or disk images — where you'll actually see the difference over a Gen 4 drive.

For typical everyday use like booting Windows or opening applications, the gains over a good Gen 4 SSD are much smaller, since most everyday tasks don't come close to saturating even Gen 4 bandwidth. But if you're running video editing projects, AI applications, and games, the difference will be immediately noticeable.

Today's top WD-Black SSD deal

The SN8100 is WD's flagship consumer drive, built on SanDisk's latest PCIe Gen 5 controller and 3D NAND. Its rated 14,900MB/s read speed puts it near the top of the current consumer SSD market, and it's one of the drives we recommend as a best-overall pick for anyone with a Gen 5-capable motherboard looking to actually use that bandwidth rather than leave it on the table with an older Gen 4 drive.

This is the non-heatsink version, which is the right call if your motherboard already includes an M.2 heatsink or shroud over the Gen 5 slot (increasingly common on recent boards) — stacking a drive heatsink underneath an integrated one can trap heat rather than dissipate it.

If your board doesn't have one built in, factor in the cost of a separate M.2 heatsink, since Gen 5 drives run hot under sustained load and can thermal-throttle without adequate cooling.

One honest caveat: PCIe Gen 5 drives like this only reach their rated speeds on a motherboard and CPU platform with genuine Gen 5 M.2 support — check your board's specs before buying, since plugging this into a Gen 4 slot caps performance at Gen 4 speeds and makes the premium harder to justify.

If you have a Gen 5-ready system and want genuinely top-tier storage speed, the SN8100 is a strong buy.
