Samsung 870 EVO SATA III 2.5-Inch Internal SSD

Samsung markets the 870 EVO as an all-star, and the framing is less hyperbole than positioning. This is a SATA drive released into an NVMe world, which means its job is not to be the fastest storage available but to be the fastest storage available on the connector most machines actually have. The 2TB capacity lands in the sweet spot for a boot-plus-library setup or a bulk secondary drive. Sequential performance reaches 560MB/s read and 530MB/s write — the practical maximum for SATA 6Gb/s. Anyone with an M.2 slot should look elsewhere. Anyone without one is looking at the ceiling of what their hardware can do.

The 2.5-inch chassis is the most widely supported shape in consumer storage, dropping into desktop bays, older laptops and NAS enclosures alike. Samsung reports compatibility testing against major chipsets, motherboards, network-attached storage units and video recording devices, and the interface negotiates down to SATA 3Gb/s and 1.5Gb/s for genuinely old hardware. Practical ownership details favor the drive too: the shock specification is listed at 1,500 G over 0.5 ms half sine, and encryption support covers Class 0 AES 256, TCG/Opal v2.0 and Microsoft eDrive through IEEE1667. A larger variable buffer handles write acceleration and long-term performance consistency. With up to 2,400 TBW behind it, this is a drive built to be installed once and forgotten.
