    Hey there,

    I backed the UDOO X86 performance edition and am really looking forward to it.
    I am planning to replace my cubietruck (1 HDD (2.5"), disk a) and my HTPC (4 HDDs (3,5"), disk b .. e) with it.

    OS (Debian, most likely) will be installed to eMMC.

    Now, there is one SATA port and three USB3.0 ports.

    Since disk a is holding my music library I want it to be fast, it will be attached to the SATA port then.
    The big drives b to e, holding backup and movie library, will be attached to one USB3.0 ports with a HUB (I will provide a 12V PSU) since they don't need to be as fast I guess.

    The USB3.0 specs are 625MB/s bandwith. Is the calculation 625MB/s / 4 = 156MB/s somehow realistic so I will be getting at least ~50MB/s of R/W on them? Would they benefit from being attached to two USB slots instead of one?

    What do you guys think of this? Am I missing something, is there a better way?

    Thanks for your input,
    onek

    Hi there,
    Seems a really big build! But you'll unlikely use all the 4 contemporaneously, and I doubt that a hub would permit that either way. So in case, if you predict to use more than one in the same time, it's better to use 2 hubs.
    Unfortunately the only SATA port miss the multi-SATA capability, so you can easily go with this solution.

    Have fun,
    Ek5

    Thanks for your input.
    You are right, most likely only one disk will be r/w'd. Anyways, there are two data and two backup disks. I'll hook up a data and a backup disk to each hub then.

    Bandwith wise will be very much ok then. Now I only have to figure out how to put 4 disks and the UDOO on a wooden plate nicely... :)
