I have an old HP Desktop and didn't want to shell out over a thousand bucks for a new PC. By adding a Solid State Drive, I'm amazed at how fast my PC boots, basically in about 30 seconds using windows 7. I don't use my Desktop for gaming, but it was frustrating just how slow the mechanical 7,200 rpm drive was. I did an install of Windows 7 using the back up discs and loaded everything onto the SSD. I've read that cloning a drive can be frustrating and this particular drive does not have the adapter needed for cloning. The OEM install is a long and pain staking process, but after all the updates are done, I'm pleased to report that I have no issues. Many users are against loading all of the files on the SSD, I don't plan on overly taxing the drive and if something should happen, I have a perfectly fine OS on the old hard drive. I've seen a lot of shall I say, paranoia of a failing SSD, and why one would load the OS and applications on this drive and use a separate drive for storage. Again, I use my pc for basic tasks only here. The Sales associate did not sell me an adapter to screw this into the bay, so I was a little upset, but I simply zip tied it just above where the old Hard Drive sits. This doesn't seem to be a problem since an SSD has no moving parts.
