in fact I'm not a connoisseur but I can share my experience and it is rather positive. so I switched to a single HDD to my SSD boot and I can say it in terms of speed is the day and night. my pc which put roughly a minute to completely start must now put a quinizaine seconds see less is instantaneous limit as the difference is obvious. to give you an example windows 7 logo has no time to regroup as the desktop appears almost in place. it said. the access to files and other records and very fast too, is the on / off virtually no latency. I have not had the opportunity to test it more thoroughly, but first impressions are very positive. there are still a plus, but the bulk is reduced to its simplest expression, ie the ssd, a package and that's it. will you fend for screws and cable in the hope that you have aside. else, the capacity sufficient for an OS becomes more limited if one is hard to see a gamer gamer a short while, we quickly made to complete it, but this is especially the justice portfolio.
