Manufacturer description

The Kingston SSDNow UV400 240GB is a 2.5-inch SATA drive aimed at anyone still booting from a mechanical disk. Kingston pairs a four-channel Marvell controller with flash memory to hit ATTO transfer speeds of up to 550MB/s read and 490MB/s write, plus random 4K throughput up to 90,000 read IOPS and 15,000 write IOPS. In practice that means boot times, application launches, and file copies land roughly 10 times faster than a 7200RPM hard drive on a SATA Rev. 3.0 motherboard. Because the UV400 has no spinning platters or moving heads, it is shock- and vibration-resistant and less likely to…

Frequently Asked Questions

How fast is the Kingston UV400 240GB SSD?

Kingston rates it at up to 550MB/s read and 490MB/s write on ATTO baseline testing, with random 4K performance up to 90,000 read IOPS and 15,000 write IOPS.

Will this SSD fit my laptop?

It is a standard 2.5-inch SATA drive (model SUV400S37/240G), which fits the common 2.5-inch bay in most laptops and desktops. Confirm your bay height clearance before ordering.

Is it really 10 times faster than a hard drive?

Kingston's 10x claim is based on out-of-box performance against a 7200RPM hard drive using a SATA Rev. 3.0 motherboard. Real-world gains vary with your host hardware, software, and workload.

Is 240GB enough storage?

It is sized for a boot drive holding Windows, applications, and a few games. If you store large game libraries or video files, plan to pair it with a secondary drive.

Does it come with cloning software or mounting hardware?

Kingston sells the UV400 as a bare drive and also as a bundle kit for easier installation. Check the specific listing you order to see which configuration is included.
