What customers say about "Features"
PNY CS900 120GB Internal SSD
  • Decent quality, easy to fit as well.
  • Excellent product easy to install and very fast.
  • Super easy to install, one of the easiest and cheapest upgrades you can give a PC and for this price it's hard to justify not doing it.
  • Simple to fit, good make, fast and cheap.
  • It's an easy fit but is a bare drive with no cloning software.
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.
