1 TB SATA SSD for everyday computing

The Samsung 870 EVO MZ-77E1T0E is a 2.5-inch internal solid-state drive built for consumer workloads. It delivers up to 560 MBps sequential read and 530 MBps sequential write speeds over a SATA III connection. The drive uses 6th-generation V-NAND and an MKX controller to sustain performance during multi-tasking.

Fits 2.5-inch bays and SATA ports

Installation requires a standard 2.5-inch drive bay and a SATA data plus power cable. At 2.38 mm height it suits most laptops, desktops, NAS units and video recording devices. The drive is backward compatible with earlier SATA revisions and managed through Samsung Magician software.

1 TB capacity with 600 TBW endurance

One terabyte provides space for operating systems, applications and large media libraries. The 600 TBW rating supports heavy daily writes such as 8K video processing. When the SATA interface limit is reached, sequential speeds plateau at the rated 560/530 MBps.

Questions about this item

How much data can the 870 EVO 1 TB write before reaching its endurance limit?

The drive is rated for up to 600 TBW over the warranty period, so it can absorb heavy daily workloads for years before wear becomes a concern.

Does the 870 EVO run hot or loud when it is under continuous load?

It has no moving parts and draws modest power over the SATA interface, so it stays silent and only warm to the touch during sustained reads and writes.

What connector and bay does my system need to install this 2.5" SATA SSD?

A standard 2.5-inch drive bay and a SATA data plus power cable are required; the drive plugs directly into the motherboard SATA port.
