250GB SATA III SSD for mainstream PCs

The Samsung 860 EVO 250GB drive uses V-NAND 3-bit MLC memory and a Samsung MJX controller. It fits 2.5-inch bays in laptops and desktops. The 512MB Low Power DDR4 cache helps sustain performance across everyday workloads.

Capacity and headroom at 250GB

Sequential reads reach up to 550 MBps and writes up to 520 MBps. Random read IOPS hit 10,000 at QD1 and 98,000 at QD32. Random write IOPS reach 42,000 at QD1 and 90,000 at QD32. Heavy sustained writes will eventually saturate the SLC buffer and slow down.

Thermals noise and power draw

Active power averages 2.2W with a 4.0W burst maximum. The drive operates from 0°C to 70°C and tolerates 1,500G shock. With no moving parts it runs silently in normal use.

Questions about this item

Will the 2.5 inch SATA III 860 EVO fit and work in my older laptop that only has a SATA II port?

The drive uses a standard 2.5 inch SATA connector, so it physically fits any 2.5 inch bay. It will operate on a SATA II port at the port's native speed.

How can I verify the Samsung MJX controller and V-NAND 3-bit MLC are performing correctly after installation?

Run a benchmark tool such as CrystalDiskMark; sequential reads should approach 550 MBps and writes 520 MBps, while 4KB random reads at QD32 should near 98,000 IOPS and writes 90,000 IOPS.

Does the MZ-76E250B/AM retail box include a 2.5 to 3.5 inch mounting bracket or a SATA data cable?

The package contains only the 250GB 2.5 inch SSD itself; mounting hardware and SATA cables must be purchased separately if your system does not already have them.
