Samsung 860 EVO M.2 250GB SATA SSD

The Samsung 860 EVO M.2 2280 250GB drive uses a SATA III interface and V-NAND 3-bit MLC memory. It is built for consumer laptops and desktops that need a compact 2280 form factor. The MJX controller manages sequential reads up to 550 MBps and writes up to 520 MBps.

Thermals noise and power draw

The drive operates between 0°C and 70°C with a maximum shock rating of 1500G. Idle power draw is 50 mW and active consumption reaches 2.2 W. With no moving parts the unit runs silently in normal workloads.

Bundled accessories and software impact

The package contains the M.2 SATA SSD and a user manual; cables screws and brackets are not included. AES 256-bit hardware encryption meets TCG Opal 2.0 and IEEE 1667 standards. TRIM garbage collection and S.M.A.R.T monitoring maintain performance when the operating system supports them.

Questions about this item

How do I install the M.2 2280 SATA III SSD in my laptop?

Insert the drive into an M.2 slot that supports SATA signalling, then secure it with the mounting screw; the common mistake is forgetting the screw, leaving the drive unseated.

What maintenance or replacement will the 860 EVO 250GB need later?

The drive has a 150 TBW endurance rating and 1,500,000-hour MTBF; when written data approaches 150 TB, plan a replacement.

What limit appears first during sustained writes on this 250GB model?

The 520 MB/s sequential write ceiling is reached before thermal throttling, so sustained large-file copies plateau at that speed.
