64GB SATA SSD for desktops and laptops

This 2.5-inch internal solid-state drive uses 3D NAND flash and a SATA interface to replace a mechanical hard drive in compatible systems. It fits standard 7mm drive bays and operates within a 0°C to 75°C range. The SM2256KAB controller manages error correction, bad-block mapping and low-power DevSleep states.

Capacity and headroom for light workloads

The 64GB capacity suits operating-system installs, essential applications and modest document storage. Sequential reads reach up to 400MBps and writes up to 100MBps, so large file transfers will saturate the drive’s write path quickly. Heavier multimedia libraries or modern game installs will exceed the available space.

Supported commands and power features

The drive supports TRIM, NCQ and S.M.A.R.T. monitoring to maintain performance and report health over time. DevSleep enables an ultra-low-power state during system idle periods, reducing overall platform energy draw. Built-in ECC and wear-levelling algorithms extend the usable life of the 3D NAND memory cells.

Questions about this item

Will this 2.5" SATA III 64GB SSD work in my older laptop that only has a 2.5" SATA bay?

Yes, the 2.5-inch form factor and SATA3 interface match any standard 2.5" SATA bay in laptops or desktops, and the 7mm height fits most drive caddies.

How can I verify the drive is performing at its rated 400MBps read and 100MBps write speeds after installation?

Run a sequential benchmark such as CrystalDiskMark or AS SSD; you should see results approaching the 400MBps read and 100MBps write figures under ideal conditions.

Does the package include a mounting bracket or SATA cable, or do I need to buy them separately?

The drive itself weighs 40g and measures 100mm x 69.9mm x 7mm; brackets and cables are not included and must be sourced separately if your system lacks them.
