Frequently Asked Questions

Will the Samsung 870 EVO 1TB fit my PC or laptop?

It uses the standard 2.5-inch SATA form factor, so it fits any desktop 2.5-inch bay or a laptop drive slot with a SATA connector. You need one free SATA data port and a SATA power connector; no M.2 slot is required.

Is the 870 EVO faster than an NVMe SSD?

No. The 870 EVO is a SATA drive, and SATA is a slower interface than PCIe NVMe by design. It is the right choice when you have no free M.2 slot or want extra bulk storage rather than the fastest possible boot drive.

What controller and memory does the 870 EVO use?

Samsung pairs its latest V-NAND flash with the new MKX controller in this generation. Samsung credits that pairing for the EVO series' in-class performance and reliability.

What warranty does the Samsung 870 EVO come with?

Warranty length and endurance rating are not listed in this product's specifications. Check the current Amazon listing or Samsung's official support page for the terms that apply to model MZ-77E1T0.
