I just had to replace my sata cable after I upgraded psu and gpu in my desktop and the sata cable was really tight because it had go around the new huge GTX470 gpu. Anyway are all sata cables the same or is there transfer data rate difference? The only cable I could find local in store was a standard sata cable from staples and the package notes that it's for 150mbs , but the sales rep. told me they where all the same is he a idiot? I am using it right now for the first time no noticble problems. Thanks for info/help!
