My buffered write rate went down significantaly? I did run into a problem formating the drive after i put them in RAID 0 mode. It wouldnt do a full NTFS install, keep getting errors. I just recreating the array and chaning channel but no luck. I had to do a quick ntfs format so i dont know if that makes a difference
