Awards and Reviews
UV400 SSD Newegg

Nice, Light, slim ... well built

Installed in a Dell Optiplex 7010 Small Form Factor desktop which took only about 10 minutes. I spent more time arranging the SATA cable than I did physically mounting the SSD in the drive tray.

Super quick clone of my Windows 7 OS & files from the existing 2.5"" 500gb HDD to the Kingston UV400 using the FREE version of EaseUS Todo Backup only took about 25 minutes.

Reboot with some quick changes to the boot order of the Dell BIOS and the SSD did it's first launch of my machine .. WOW

Should've t done this sooner .. computer now has wicked FAST boot load times !

No "cons" with the drive. It was packaged well and protected.

Spent more time finding a SATA cable to fit inside the Dell than I did installing the drive.”

Works great! “It is an awesome setup and waaaay better than adding a powered external drive, which would create clutter and noise. This is small and barely noticeable with the one Y wire going to the back of the wiiU that uses both ports for max power. Runs flawlessly.” Read Full Review
Great Little Drive “FAST! Went from RAID 0 with 2X SATA3 7200RPM to this little guy and it's so much faster!” Read Full Review
Great Buy!!! “The speeds were phenomenal 447 Read speed and 427 Write. I was blown away, compared to my Raptor HDD which I tested at 102 read and 90 write at 10000 RPM.” Read Full Review
If You're Still on a Standard HDD, Get an SSD “My reboot times and general loading times are SO MUCH FASTER now. If you're still on a standard HDD. Get yourself an SSD.” Read Full Review

SSDs for Consumers
Hard drive replacement

Solid-state drives are the next evolution of PC storage and run faster, quieter and cooler than the aging technology inside hard drives. With no moving parts, SSDs are also more durable and more reliable than hard drives.

For desktops and notebooks

Kingston solid-state drives will make your system more responsive so it boots quicker, loads applications faster and shuts down faster. They’re available in upgrade kits that include software to clone your files and OS in minutes.

Revive older systems

Solid-state drives will not only increase performance but can also be used to breathe new life into older systems. Choosing an SSD can save you the cost of buying a new PC by reviving the system you already own.
