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!"
Yeah this was a huge dissappointment for me as well. I would love to stream my divx/xvid movies as well. I use the 360 for my WMV HD, but I watch my xvids on my old xbox with XBMC, it just can't handle any divx hd so i would love to be able to watch them on my HD. Come one micorsoft reconsider!!!
