I've been a happy PS3 owner for over a year now, A good friend sold it to me for a price I could not refuse and I haven't gone back to Microsoft ever since ( the 360 has been relagated as my 2 year daughter's media player ).
The only concern I had was that this Ps3 had a 40Gb hard drive and I eventually would have to upgrade it... and that time is now!
After carefully researching what hard drive to buy ( cnet, user reviews, forums, etc ) I decided to go with the Western Digital Scorpio Blue WD5000BEVT 500GB 5400 RPM 8MB Cache 2.5" SATA 3.0Gb/s Internal Notebook Hard Drive ( available on newegg.com for a messily $89.00 w/ free shipping.) a lot of PS3 owners had made the switch and recommended this drive online.
So tonight I'll back up my current drive ( I'll let you know how that turns out ) and we'll see if it works for me or if I just fuck my whole system up ( I've been know to do that from time to time )
Cross your finger and wish me luck.
