    Hi everyone,

    My NP8130 haven't arrived at my doorsteps (nor did it get shipped yet T.T been waiting for like 5 days for it to ship)....

    So last night I bought a Thermaltake HDD docking station (eSATA + USB 2.0) that takes two hard drives.

    And via USB, it detects both of the drives however, when I plug it via eSATA into my old ASUS laptop, it only detects one of the drives.
    And as it turns out that my ASUS laptop doesn't support port multiplier function on the eSATA >.<;;

    So do you guys know if the NP8130 supports port multiplier function on the eSATA?

    Thanks :)

    As far as we know it does NOT have port multiplier function.

    USB 3.0 is faster than esata anyway. Hold out for that? I don't know about port multiplying on the esata here, it will take some looking around.

    The early tests showed that e-Sata is faster than USB 3.0, actually.

    I was disappointed :(

    Nope, unfortunately it does not support port multiplier functions. Another user had this problem earlier with the P150HM

    What early tests do you mean? I think USB 3.0 is superior to eSata 1.0 in every way. Any inefficiencies are due to slow USB and bridging controllers. The actual problem is that mechanical drives do nothing on USB 3.0. Only fast flash memory or SSDs can actually use the bandwidth of USB 3.0.

    Were those tests done with mechanical drives? A mechanical drive with SATA to USB bridging will be slower than a mechanical drive directly linked to eSata. Mechanical drives can barely touch the available bandwidth of USB 3.0 so you never see that performance.

    lol but whether or not USB3.0 is slower than eSATA or vice versa argument.... if there is no port multiplier on the eSATA but there is for USBs then I'd go for the USB3.0 one... I'll probably go back and return this and get the other one instead.... I hope the retailer won't be a when I return it... lol.

    You are right, it was done on mechanical drives.

    Again the old discussion : who is faster eSATA or USB :)

    Will the thing is, faster in what? If you use a USB port to connect a SATA HDD or a SATA SDD, then even if the USB3.0 (5Gb/s) transfer speed is higher than a SATA II (3Gb/s), but the SDD is a SATA then whatever the speed of the future USB could be, it's not counting, and always the SATA will win because its direct and doesn't need translating.
    The USB3.0 is faster than the SATA II only with stuff that are not SATA interface (like a flash stick for example). This without taking about the SATA III (6Gb/s).
    There is an enclosure that can be connected via eSATA/USB2/USB3 but it accomedate only one drive :
