I’ve been running a 2.5Tbyte xserve raid for 1 yr. It’s stripped as one big volume so i can do uncompressed HD. I bought the apple care protection plan and i’m glad i did. I had a drive go bad and they replaced it overnight. The cool part was that even though it’s one big drive I didn’t lose any info. I have had occasional drop frame error messages on playback, but I’ve never been able to isolate it to the xserve and they are so infrequent, they’re not a serious issue. It was a spendy decision, but I’m glad I’ve got it.
