    Hi,

    Im looking at purchasing the ultrabay SATA adapter for use with a 2.5" SATA disk.

    Could someone please advise what SATA transfer speed the ultrabay adapter supports?

    Is it 1.5Gb/s or 3Gb/s?

    Thanks

    1.5 GB/sec.

    But it's all theoretical speed. In real life I hardly see transfer speeds exceeding 25 MB/sec.

    Vista has some bugs concerning slow file transfers. MS has yet to come up with any definitive solutions.

    I believe the "bugs" in file transfers in Vista is called "DRM".

    I think even within Vista, there are variations in transfer speeds.

    I previously had a laptop running Vista Home Premium. Now I am running Vista Ultimate. Transfer speeds seemed faster under Vista Home Premium.

    These issues were with network file copies....not local hardware IO.

    But I am experiencing slow local file transfers as well, usually around 20mb/sec.

    20MB from what to what? With an average low density 5400rpm hard drive, ~20MBps isn't far from normal.

    20MB/sec from the primary hard drive to the secondary hard drive mounted on the hard drive adapter.

    Transfer speeds to external USB 2 hard drives are usually a bit faster.

    Is the interface that connects to the Ultrabay IDE or SATA? I believe I recall reading that the primary hard disk was SATA but the Ultrabay connector was IDE.

    It's SATA. I have a T61 and I use two separate distinct OSs on it. I have XP on the primary drive, and Vista on the Ultrabay drive. I had to set the ultrabay drive as the boot priority in the BIOS, but now w/the Ultrabay drive in - it boots Vista, and with it out, it boots XP. There is a hotfix for the slow file copy, but that's Vista, and non-specific to this issue.

    I had to install Vista(needed the DVD drive) with the 2nd drive in the regular drive bay, and the DVD drive in the ultrabay. I used it that way for a day or two, and notice no performance decrease between being in the main bay or the ultrabay(and I play a few newer games... NWN2, TF2, etc).

    For the T61 the primary drive is capable of SATA II the SATA ultrabay adapter is SATA I

    I have used the SATA ultrabay adapter with a 2.5" 5400RPM HDD and an external USB drive holding a 3.5" SATA II 7500RPM drive. The SATA ultrabay adapter HDD is much faster than the external USB HDD. The USB 2.0 is quite a bottleneck.

    It's 1.5Gb. Until recently, there were no 2.5" 3Gb SATA drives.
