    So assume a 6 port on board sata controller, 6 of these and 30 x 2Tb
    disks....

    48Tb usable with hware raid....if you did software raid....R5(9+1),
    54Tb....

    Now that is insane.

    but oh so cheap.....in terms of per TB...physical storage of those
    disks would be an issue of course...and the psu(s) to get them to spin
    up.....

    regards

    Pretty cool product! It'd be interesting to see the real-world IO
    performance that would result based on the config you've outlined
    above.

    Effectively its one hugh stripe....Raid0((R5(4+1)+(R5(4+1)+(R5(4+1)+(R5
    (4+1)+(R5(4+1)+(R5(4+1))

    A lot of spindles...but, yes I wouldnt be surprised if its fairly
    slow...but it depends on its use...if you just want storage.

    My experiance with port multipliers was not a positive one.

    Ended up with 4 esata to sata cables going in the hole the port
    multiplier left in the case and 2 2 port esata cards. It seems that
    thrashing access to one disk leaves access to the other one very very
    laggy, moreso then I would expect. MP3 playback off one disk would
    stutter and break up when copying video files between another disk on
    the multiplier.
