Samsung 870 EVO SATA Internal SSD 1TB

Overview

The Samsung 870 EVO is a 2.5 inch SATA III solid state drive rated for up to 560 MB/s read and 530 MB/s write speeds, with 600TB of endurance and a 5-year warranty. It fits any laptop or desktop bay that uses a SATA connector, a straightforward upgrade over a hard drive.

This is a SATA drive, not the newer NVMe standard, and that difference matters more than any other spec here: no amount of buffer tuning gets a SATA III drive past roughly 560 MB/s, because the interface itself sets the ceiling. That makes it a fit for one situation in particular, an older laptop, desktop or NAS bay that only has a SATA connector, where it is a genuine speed and reliability step up from a spinning hard drive. Buyers chasing NVMe-class speeds should look at an M.2 drive instead.

• 1TB 2.5 inch SATA III solid state drive
• Up to 560/530 MB/s sequential speeds
• 600TB total bytes written rating
• 5-year limited warranty

Who it's for

Suits anyone upgrading an older laptop, desktop or SATA-based NAS from a hard drive, or replacing a failing SATA SSD, where reliability and warranty matter more than chasing the fastest possible speed. Not the right choice for a build with an open M.2 NVMe slot, where a native NVMe drive will outperform it.

Pros and cons

Performance notes

As a SATA III drive, the 870 EVO's speed ceiling is set by the SATA bus itself, so its 560/530 MB/s figures sit near the top of what that interface can deliver rather than what an NVMe drive would reach. A larger variable buffer is what keeps write speeds up during longer, sustained transfers instead of falling off partway through. The 600TB endurance figure and 5-year warranty describe how much writing the drive is built to absorb over its life, not day-to-day speed.
