Let the hive mind of Engadget get that for you.
"I'm looking for a solid state drive, around 32 to 64GB, for use in my web server. The drive will contain my web sites and the operating system, either Windows Server 2008 R2 or Ubuntu. Large storage is handled by a separate RAID array, so capacity is not an issue. Rather, I am looking for the fastest, longest-lasting, and most reliable drive under $150 that is suitable to my application. Any thoughts? Thanks!"
Are you sure you got a 8Gbyte MP4 player? Many of these players are actually 1Gb or less players with a modified formatting so it _seems_ like 8Gb, until you fill it pass the limit of the real flash drive and everything goes corrupt. It's a very popular scam nowadays.
