I'm doing something "gross" with ZFS & Plex on a little Intel NUC that I
have here at the house to provide me with a nice little NAS at home. I'm
using 2x USB2 external disks as the mirror.
I noted that the two USB2 disks I'm using in a mirror seem to "stall"
from time to time and its not clear to me why.
I'd like to poke further into the USB system but I'm not sure where I
should start to see if there is something amiss with the hardware (e.g.
the disks suck) or if FreeBSD is losing track of something during I/O
leading to a stall/timeout.
I'm not seeing data loss or anything, I just note from time to time
during large file transfers that the clanking/grinding sound of the
spinning rust on my desk completely stops, the encoding of the video
files stops (so its waiting for a read to complete) and its gets much
quieter in my office. :-)

I think I'm going to grab one of these fancy 5-disk USB 3 enclosures I
see on the Internet. ;-)
Most of the consumer grade units seem to have one or more issues (no NCQ
depth more than 1, loud/bad fans, hard to get a real JBOD mode, JBOD
mode eats serial numbers making ID hard).
I think I settled on the TERRAMASTER D5-300 USB3.1
I'll post back results when it arrives and I get done swearing and
cursing during the replacement.
