What customers say about "Features"
Kingston UV400 240 GB Solid State Drive SATA 3 Standalone Drive
  • Installed into a Macbook Pro Mid 2009. Formatted, installed Mac OS and working great!
  • The physical installation was relatively easy.
  • This one came fast and was easy to install.
  • Works well easy installation.
  • Amazing easy install. Laptop easy fresh install currently running Windows 10.
Kingston A400 Solid State Drive (2.5 Inch, SATA III)
  • Very light, easy to install (unscrew case, unscrew old drive, screw in new drive).
  • The drive is very lightweight, easy to install. Seems quite fast.
  • Fairly easy to install and to clone my existing drive .I'm not disappointed!
  • Only drawback was that I thought it would be easy to clone the old drives to swap the new ones in, but that was a total pain, so ended up doing a fresh install and copying data across to new drive.
  • My issue is that there is no drive imaging software support from Kingston for the this range of SSDs, most disappointing.
