    What am I doing wrong here?

    This is a brand new build with 3 drives, one parity and I have set up everything as a pool and connected my other PCs to the network shared drive via Samba.

    Am I missing something? The write speed from those other PCs is consistently under 10Mb/s...

    SnapRAID has no bearing on the read/write speeds of either the pool OR the drives underneath. Unless it's actively running a sync/fix/check/etc, that would be putting a heavy load on the drives and slow down any concurrent IO operations. I would look into issues of poor performance related to MHDDFS. Also try reading/writing the individual drives outside of the pool.

    have you checked your network connection, as that sound like its running on 100Mb/s and not 1000Mb/s

    ethtool eth0

    Your looking for the speed line, just an idea as I've had this issue before and it turned out my switch was failing, i would get fill 1000Mb/s after a power cycle but after a while it would drop to 100Mb/s.

    Hmm, the speed says 1000Mb/s.

    May have found the problem-- the write speed is normal when both my laptop and ubuntu server are connected via ethernet. The speed only drops off when writing over wireless.
