Called Western Digital over the Raptor's 74GB performance. When loading a 391MB audio file from the Raptor [10K rpm] it takes 95 seconds; from my old ATA133 Maxtor ONLY 42 seconds...repeatedly. WDC is pointing fingers at the EPoX MB, maybe drivers. I have all the latest BIOS and drivers that I can find. I must add that I have a SATA converter on the Maxtor using a SATA cable. In converting an WAV file to MP3 using both HD's for read and save for comparison, the Raptor takes about 50% longer. Any thoughts that can assist?
