actually raptors aren't the best compared to fiber channel SCSI drives which are at 15,000rpm but those are 800$+scsi card. actually hybrid drives may be better route than 10,000 rpm Hd's or ram drives but as of now i have only seen a 40gb model, add 300+ for the case then you have to fork over serious dough for 4gb dimms, just look what happened with quad sliit was supposed to be the best thin thn 8800gtx came out and beat it. Who knows if 10k HD's become standard or we may see a new technology in the future that is more viable.
