    So just to be clear its a USB3.0 to eSATA adapter that supports Port Multiplying....

    The title of the thread was rather confusing since all USB supported "Port Multipying" (it's called a USB hub)....

    A device has ONE USB to many USB then call HUB, not port multiplier :).
    That is what I understand.

    After i look at the title again! You are right...

    It should be USB3 to eSATA adapter fully support Port Multiplier Ware

    Let me see whether I can edit the title for better description :)

    Speed?

    I'm also very interested in this product--have any of you done any speed tests? The USB 3 drive enclosures tend to be very flakey and I'm hoping this will let me resurrect my eSATA enclosures for use w/ my new iMac (w/ USB 3, but no eSATA, obviously).

    Thanks!

    Finally I test this adapter with a SSD 120GB HDD, i can get 269MB/s of out of it
    and 3.5" 7200rpm about 82MB~110MB depend on the model

    I'm wondering if this USB3-to-eSATA will indeed support my MacGurus Burly Port Multiplier Enclosure - http://www.macgurus.com/store/Item/BurlyPortMultiEncl

    FYI... and just a warning to others.
    I've contacted MacGurus about this and was told it would be problematic... "Not without errors." were the exact words from MacGurus.

    Seeing as this thread was resurrected again,
    Has anyone tried this in an environment running 24/7 or at least enough to know whether it is stable or not? Any random drops etc? Would be interested to have this attached to Mac mini server

    DATOptic USB3.0 adapter

    Yes You can run 24/7 but you need to load this app
    https://www.macupdate.com/app/mac/31158/keep-drive-spinning

    "Because some of HDD do not respect the System Preferences settings"

    bxs

    I have 3x of them.
    As long as you connect the box to the USB adapter 1st before you connect to your MAC
    Then it will work
    If you do it other way around, then no drive will show up :)
