Kingston's ssds & storage lineup sits within the broader category mid-tier; price and specs are the deciding factors over brand loyalty here.

Frequently Asked Questions

How fast is the Kingston A400 960GB?

Kingston rates the A400 at up to 500MB/s sequential read and 450MB/s sequential write, which is effectively the ceiling of the SATA III interface. Kingston describes this as roughly 10x faster than a traditional mechanical hard drive.

Will this SSD fit my laptop?

The A400 is a standard 2.5-inch SATA drive, the same form factor used by most laptop and desktop hard drives. If your machine has a 2.5-inch drive bay and a SATA connector, it fits. Ultrabooks that only accept M.2 sticks will not.

Is 960GB enough space?

960GB is enough for a Windows install, a full productivity and creative application suite, and a meaningful game library on the same drive, which is why Kingston positions it as a full hard-drive replacement rather than a boot-only volume.

How reliable is the A400 compared to a hard drive?

The A400 is built on Flash memory with no moving parts, so there is no head, platter, or motor to fail from shock or vibration. Kingston states it is less likely to fail than a mechanical hard drive and that it runs cooler.

What warranty does the Kingston A400 come with?

It carries a 3-year limited warranty from Kingston. Check the product listing for current regional warranty terms and support details before purchase.
