For what it's worth, I started playing with USB + flash + ZFS and was most unhappy for quite a while.
I was suffering with things hanging, going slow or just going away and breaking, and thought I was witnessing something zfs was doing as I was trying to do mirror recovery and all that sort of stuff. On a hunch, I tried doing UFS and RAW instead and saw the same issues. It's starting to look like my USB hubs. Once they are under any reasonable read/write load, they just make bunches of things go offline. Yep - They are powered and plugged in. So, at this stage, I'll be grabbing a couple of 'better' USB hubs (Mine are pretty much the cheapest I could buy) and see how that goes. For gags, take ZFS out of the equation and validate that your hardware is actually providing a stable platform for ZFS... Mine wasn't... Nathan.
