4TB 2.5 Inch SATA SSDs
Samsung 870 EVO 4TB SATA 2.5 SSD
Samsung PM893 3.84TB SATA 2.5 SSD
The 4TB 2.5 inch SATA drives here are both from Samsung. The 870 EVO 4TB (MZ-77E4T0BW) reads and writes at up to 560/530 MB/s, and the PM893 3.84TB (MZ-7L33T800) reaches 550/520 MB/s with end-to-end data protection. Samsung covers both with a 5 year warranty.
The 870 EVO is the consumer drive, suited to desktops, laptops and game or media libraries. The PM893 is a data centre SSD built for servers, NAS boxes and workstations that run around the clock. Either fits any 2.5 inch bay with a SATA port, but SATA tops out near 550 MB/s, so a free M.2 NVMe slot is faster.
Frequently asked questions
Why is the PM893 3.84TB and not 4TB? Enterprise drives keep extra flash in reserve for endurance and steady performance, so usable capacity is slightly lower.
Will a 4TB SATA SSD work in an older laptop? Yes, if it has a 2.5 inch SATA bay. It is a direct replacement for a hard disk.
