Everything that decides whether the Samsung 870 Evo is the right drive: controller, DRAM, NAND, rated endurance, PS5 and laptop fit, and how it compares with the obvious alternatives. Hardware facts are taken from the reviews and datasheets listed at the bottom; capacities and speeds come from our comparison of 60 drives.
Who it’s for: The SATA drive to pick when you want the most consistent performance and the highest endurance in a 2.5-inch bay: DRAM, TLC and 600 TBW per TB. Skip it for: Machines with an M.2 NVMe slot; SATA tops out around 560 MB/s.

The Samsung 870 Evo is a SATA drive: it fits a 2.5-inch drive bay. It will not work in an M.2 slot that only supports NVMe, and it does not meet the PS5’s NVMe requirement. If your machine has an NVMe slot, an entry NVMe drive is many times faster for about the same price per terabyte.

We show retail prices only while we can refresh them at least every 24 hours. For market context: TrendForce’s 16 Oct 2026 retail sample runs $133–$250 per TB for mainstream 1–2TB drives, and NAND contract prices are forecast +15 to +20% for 4Q26. Check any listing against that range with the price per TB calculator, and see the SSD price chart for the trend.
