Pros: Can't think of any!

Cons: After numerous problems with the first one, I sent it back for another unit. I had my SSD loaded just the way I wanted when, I admit I made a mistake here as I attached my hard drive to the unit and fired it up, I had some existing files on my 640GB hard drive and they wrote over everything on my SSD. I tried to perform a recovery but everything on the SSD was lost. After starting over and making sure the hard drive had the OS and all my files on it as I wanted, things appeared to work, but there was not an increase in speed anywhere to be found. My 640GB hard drive is a SATA III drive, my Windows Index score was still 5.9 and when I tried to use either drive seperatly, neither would boot up. My understanding was that the front end data was supposed to be off loaded to the SSD, but that is was basically mirroring the two drives. Anyway, I've given up on it. It's useless.

Overall Review: Glad to hear that it works for some people.
