2TB SATA III internal SSD

The Samsung 870 EVO MZ-77E2T0B/AM is a 2TB 2.5-inch internal solid-state drive built for consumer desktops and laptops. It uses V-NAND memory and a SATA III interface to deliver sequential reads up to 560 MBps and writes up to 530 MBps. A 2GB Low Power DDR4 SDRAM cache supports sustained throughput.

Check 2.5-inch SATA bay and cable

Before ordering, confirm your system has a free 2.5-inch drive bay and a spare SATA data and power connection. The drive uses the standard SATA protocol and fits the common 2.5-inch form factor used in many laptops and desktop cages. No additional adapter is required when the bay and cables are present.

Steady write speed with 1200 TBW rating

Under sustained load the 870 EVO maintains performance through its variable buffer and draws an average 2.5 W active power with a 4.5 W burst ceiling. The drive is rated for 1200 terabytes written and an MTBF of 1,500,000 hours. AES 256 encryption to TCG/Opal 2.0 and IEEE 1667 standards operates without slowing the data path.

Questions about this item

Does the 870 EVO 2TB come with a mounting bracket or SATA cables, or must they be bought separately?

The drive is supplied as a bare 2.5-inch SATA unit. Mounting brackets and SATA data or power cables are not included and must be purchased separately if your system does not already provide them.

How do I decide between the 870 EVO 2TB and other capacities in the same series?

Choose the 2TB model when you need 1,200 TBW endurance and up to 560/530 MB/s sequential speeds for large media libraries or heavy workloads; smaller capacities offer lower TBW ratings and less space for the same SATA interface limits.

What do the 560 MB/s read and 530 MB/s write figures mean once the drive is installed in a laptop or desktop?

Those are the maximum sequential speeds the SATA III interface allows; real-world throughput will be lower and depends on the host controller, file system overhead and whether the 2GB DDR4 cache can absorb the write burst.
