    What is your eSATA transfer speed. Mine is around 38-40 MB/s. This figure look acceptable or no?

    Apparently its ~320MB/s I was moving a 320MB ISO from my external drive to one of my internal drives and it literally finished in one Second.

    But I actually think its more like 60~120MB/s, thats what it averages. It just depends on what controller you have, and if its 1st Gen or 2nd Gen. It also depends on the drive itself, and what kind of files you're moving, although that seems kind of slow.

    It is whatever your hard drive transfer speed is.

    As you seem to suspect yourself, ~320MB/s is not accurate. You measured bs there. (According to wikipedia, the maximum net read speed of SATA 3Gb/s is 250MB/s.)

    I don't think so. Depends on how well the manufacturer implements the standard. Have def. seen various reviews where eSATA limited the speed to 80-90MB/s with a drive that could provide higher throughput when connected via SATA instead.

    eSATA is supposed to have identical throughput to regular SATA though. I guess SATA I would limit the speed of some SSD's, but SATA II would be sufficient for anything out there.

    It all depends on what you are transferring as well. If I transfer a movie folder with many large files I get around 110-120MB/s but with my music folder I get 80-90MB/s and if I transfer.. say the Adobe folder from my Program Files directory.. I'm lucky to get 10MB/s.

    For what I use it for I'd say I average 70-80.

    eSATA is identical to SATA.

    I get transfer speeds of ~70-80 MBps (for a set of big files, about half that for small files) on my external WD 320 GB 3.5" 7200rpm hard drive.

    I got about 75-80MB/sec with a 7200 80GB 8MB Seagate HD,i tought it was gonna be faster then the internal drive,nope its slower :p

    I'm gonna put a faster 7200rpm drive in the enclosure en install my games on this drive because of the acces time/loading times...

    eSATA = SATA

    The interface is by far fast enough to handle any normal hard drive so the speed you get is the drive speed not the SATA speed.

    The only way to benchmark the eSATA speed would be with a drive so fast that the interface bottlenecks like several fast SSD's in a RAID 0 Array.
