Summary: The Crucial Adrenaline solid state cache only does one partition. This means best practices for separating data and programs, or windows piles of useless files and other programs, etc, are not useable. To the best of my knowledge the San Disk ReadyCache does any drive.
Summary: If you do not use a SSHD, then this is the way to go. Adds about 50gb of cache for the most often used programs, all transparent to you. You will only notice the faster boot up, and the screens just pop on your monitor. Does not work with Win 8 as of 03/2014, but who cares about Win 8!
Summary: I have had one of these for about 3 years. Never was able to make it work correctly. It was intended for my Asus P5G41C-M LX system. Crucial said it was fully compatible. The board does not have AHCI which is required. Upon contacting them, I was told to run it in IDE.
Summary: I purchased this on newegg about 2 years ago. I have recovered my hard drive so many times I have lost count. The Crucial techs and the Dataplex techs were sending me the latest versions of firmware and software. However nothing has truely made it 100% workable.
Summary: I bought this because I already had my hard drives and wanted to try to get a bit more speed out of the main one, especially since I didn't want to shell out a lot of money for an SSD. The boot times on my PC are definitely much better, great product, I'd say worth the price.
Summary: What I love about this is that It is pretty much plug and play. You install the SSD Cache, Install the software, and it gets to work. Every startup gets a little faster. Everything gets snappier.
