I've been transferring about 5TB from a USB 3.0 enclosure with built in hardware RAID running 4x SATA III drives. The destination is an external SAS enclosure (7x SATA II) with 2x SAS cables connected to PERC 6 card.
Its been going for over 2 days straight! It's only done about 2.5TB so far...
Wondering if this is normal? I'm using robocopy to do the copy.
and if this is normal; would using esata III be any better?
hope to hear your thoughts. Thanks!
