1 TB SATA SSD for everyday systems

The Samsung 870 EVO stores 1 TB on a 2.5 inch SATA III drive rated for up to 560 MBps read and 530 MBps write. It targets consumer laptops and desktops that still rely on the SATA interface.

2.5 inch form factor fits standard drive bays

The 7 mm height and standard SATA connectors let the drive slide into most 2.5 inch bays without adapters. At 0.2 kg it adds negligible weight to a portable or desktop build.

SATA III caps throughput at 6 Gbps

Sequential speeds of 560 MBps read and 530 MBps write sit at the practical limit of the SATA III bus. Random workloads and sustained writes will fall below these peak figures.

Questions about this item

What practical speed limit does the SATA III interface impose on this 870 EVO drive?

The SATA III link caps real-world throughput at roughly 560 MBps read and 530 MBps write, matching the drive’s rated sequential speeds.

Will the 2.5 inch form factor with a 7 mm height fit my laptop bay?

At 7 mm tall and 9.6 cm wide it matches the standard 2.5 inch drive tray used in most laptops and desktops.

How do I install the drive and which step is often missed?

Connect the SATA data and power cables, secure the drive with four screws, then initialise and format the new volume in the operating system — the formatting step is frequently overlooked.
