Samsung 840 EVO 250GB SATA SSD

This Samsung 840 EVO internal solid state drive provides 250GB of storage using a SATA III interface. It uses TLC memory components and a Samsung MEX controller inside a standard 2.5 inch form factor. The drive suits desktops or laptops needing a straightforward storage upgrade.

Check SATA port and bay clearance

Verify your system has a free SATA III port and a 2.5 inch drive bay or suitable adapter before ordering. The drive measures 7.11mm in height, 69.85mm wide and 100.08mm deep, so confirm physical space inside your chassis. Ensure your operating environment stays within 0°C to 60°C and 5% to 95% humidity.

7.11mm metal casing with cable bundle

The 7.11mm metal casing fits standard laptop caddies and desktop trays without forcing. A USB 3.0 to SATA cable and a drive spacer are included in the package for data migration or external use. Low idle power draw of 0.045W helps battery life on portable systems.

Questions about this item

What comes in the box with the 250GB 840 EVO and what must I buy separately?

The package includes a USB 3.0 to SATA cable and a drive spacer. A SATA data cable and mounting screws for a desktop bay are not included.

How do I decide between the 250GB 840 EVO and other capacities in the same series?

The 250GB model delivers 540MB/s sequential read, 520MB/s write, 97,000 IOPS random read and 66,000 IOPS random write; larger capacities in the series typically raise the write figures while read stays similar.

What does the 540MB/s sequential read figure mean once the drive is installed in my laptop?

It is the sustained throughput the controller can maintain on large, sequential files; real-world speeds will be lower due to OS overhead, file fragmentation and thermal limits inside a 2.5-inch bay.
