yup, i saw that site when i was searching for info on raid drives here. everything up to raid 5 i already knew. i couldn't find any info on what drives to actually use though other than the professional drives were best, but they were out of the budget. since this isn't a mission critical server, just don't want any dataloss, i decided the samsung spinpoints had the best rating for reliability.
coorect me if i'm way off here, but from the way it was described to me, the internet radio server simply streams a single stream of music out to whoever happens to log on to the website, so there isn't a whole bunch of different streams running at once. i'm thinking that means that even though the spinpoints are only 3gb sata that they will have more than enough throughput for that environment.
