    How can I test read/write speeds to a drivepool?

    Doing some testing of some replacement solutions for DriveExtender in WHS 2k11, but I can't figgure out a good way to test read/write speeds for the different alternatives.

    I tried HD Tune, but that only tests individual drives and not the drivepool.
    I also tried CrystalDiskMark but the results don't seem to be out of whack aswell:

    The results of the benchmark looks great, but when I try to copy files to the pool it only manages to do that at 50-60MB/s, so the CDM-results does not reflect reality.

    Are the files local ? or are you "pushing/pulling" from around your network ?

    The files I move are local, moving them from a disk that is not in the pool to the pool and back again

    Then the 50-60MB/s you're getting is probably the speed of your other disk not the drivepool.

    Re: How can I test read/write speeds to a drivepool?

    I just tried over LAN and it's the same there.

    I don't think my pool can handle more then 60MB/s when I copy large amounts of data, because when I do that it moves one file after the other and then it's only writing to one disk, but if I run something like CDM it probably read/writes alot of small files that ends up on different disks and then it gets a boost in the "performance".

    The pool can probably only handle 60ish MB/s when it writes to a single disk, but I'd like a more "sciency" way of testing this then just copying some files to and from it.

    I have now run some tests with CrystalDiskMark with 3 of the Pooling sollutions for WHS, and here are the results:

    Ldisk barely outperforms StableBit, while DriveBender continues to show results that can't be taken seriously.
