Frequently Asked Questions

How fast is the Kingston A400 compared to my old hard drive?

Kingston rates the A400 at up to 500MB/s read and 450MB/s write, and describes it as about 10x faster than a traditional mechanical hard drive for boot, load, and file-transfer times.

Is 120GB enough space for a boot drive?

120GB comfortably holds Windows plus everyday applications, which is the role this capacity targets. If you store large game libraries or video files, plan to keep a secondary drive or step up to a larger capacity in the A400 line.

Will this SSD fit my laptop?

It is a standard 2.5-inch SATA 3 drive (model SA400S37/120G), so it fits any laptop or desktop with a 2.5-inch SATA bay. Check your machine's drive bay height and interface before ordering.

Is the A400 more reliable than a hard drive?

Kingston builds the A400 on flash memory with no moving parts, which the company cites as making it more durable and less likely to fail than a mechanical drive with spinning platters and moving heads.

What warranty does the Kingston A400 come with?

Warranty terms are not listed in this product's specifications. Check the current product listing or Kingston's support site for the warranty period that applies to your region.
