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. :-) sean
