Well lets see: I bought the 64 GB OCZ Core2 a few weeks ago.  I installed my Vista 64 on it.  I have 2 other drives (regular WD 640) as well where I have all my documents, movies, pics, work files, music etc.  BTW it took for ever to install Vista on that ? way way longer than my regular WD 640.
The SSD runs very well -- but the one I have is no Intel SSD.  Do more than ONE thing such as lets say, install an updated driver... and maybe downloading something or have a song playing or anything really that involves writing to the drive... and it's God awful slow ? pretty much everything freezes for a bit.
I am sure the Intel SSD is way better.  I got it since the price of the OCZ was so low AND there was a $70 rebate.  At that point it became more of something new to play with and try and it?s all on me.  Personally that OCZ is not ready for prime time.  I had read various reviews... Jmicrion controller etc... and I knew it was not the best but again for the price why not.
The boot is zippy for sure and honestly for 75% of what I do, it does its job well -- just I am not overly excited about it. In fact I have totally forgot I have it running in there and it's such new tech.  It works flawlessly - - don't get me wrong ? no errors? no crashes ? you can?t put a value on it being dead silent, very little power use? no HEAT, don?t need to defrag.  For that it?s awesome.
I am not giving up on it.  One thing I have not tried is running a game off it.  All my games are installed on the actual other HD's... thus really only the OS is on the SSD and stuff like Office, Winrar, Firefox etc.  Swap file is also on the WD 640 and all my 'work" dump folders are on the WD 640... so when I run my video encoding software, the app resides on the SSD but the video file I am working on is on one HD and the target result of the encoding goes to yet another hardrive.  This works well.
