8 TB U.2 / U.3 SSDs

The one 8 TB-class U.2 / U.3 SSD on this page is the Samsung PM9A3 7.68TB NVMe U.2 SSD (MZ-QL27T600). It is an enterprise drive for servers and storage-heavy workstations. It runs on PCIe 4.0 NVMe, with sequential reads of up to 6700 MB/s and writes of up to 4000 MB/s. Power loss protection guards data being written if power drops. Samsung covers it with a 5 year warranty.

Check the host first. The drive needs an NVMe-capable U.2 bay, a U.2 port on the motherboard or an add-in adapter card. A desktop with only M.2 and SATA connectors cannot take it directly.

Frequently asked questions

Why is it 7.68TB and not 8TB? Enterprise SSDs keep part of the flash in reserve for sustained write speed and endurance. That makes 7.68TB the usual size in the 8 TB class.

Will it work in a U.3 bay? U.3 bays are generally built to accept U.2 NVMe drives. Confirm support with the server or backplane maker.
