I have 2 HD-QSSU2/R5 drives and using HDTune, the drives are running around 80MB/sec. connected via esata. I also have some single Seagate 1TB drives that I put in Vantec external drive cases that are getting about 120MB/sec, far faster than the buffalo drives set at RAID 0 and pluged into the same esata port of my system. Anyone know how to speed these up?
