2TB 2.5 Inch SATA SSDs

The 2TB 2.5 inch SATA SSDs here are the Samsung 870 EVO 2TB (MZ-77E2T0B/AM), with V-NAND and speeds up to 560/530 MB/s; the Samsung PM893 1.92TB (MZ-7L31T900), a data-centre drive rated up to 550/520 MB/s with end-to-end data protection; and the WD Green 2TB (WDS200T2G0A-00CMW0), with reads up to 545 MB/s and low power draw. Each fits a standard 2.5 inch bay in a laptop or desktop.

Speeds differ little, since the SATA interface caps out near 600 MB/s, so choose by use and warranty. The 870 EVO suits a laptop or desktop upgrade for games, photo libraries and daily work. The PM893 is made for servers, NAS units and workstations that write data all day, and holds 1.92TB rather than a full 2TB. The WD Green is a simple secondary or bulk storage drive. Samsung covers its drives with a 5 year warranty and WD covers the Green with 3 years. The Samsung and WD models also have their own pages.

Frequently asked questions

Will a 2.5 inch SATA SSD fit my laptop? Yes, if the laptop has a 2.5 inch drive bay with a SATA connector, where a hard disk would sit. In a desktop it needs a SATA data cable and a SATA power lead from the PSU.

Is a SATA SSD slower than an NVMe SSD? Yes, NVMe drives on PCIe are several times faster in large transfers, but a SATA SSD is still far quicker than a hard disk and works in systems without an M.2 slot.

Why is the PM893 1.92TB and not 2TB? Enterprise drives keep extra spare flash in reserve to handle heavy, continuous writes, which leaves slightly less usable capacity.
