Hi guys,
I've seen USB 3 questions from time to time here and I would like to share this:
my Supermicro ASRi- 2758F has external and internal USB 3.0 headers. While I started my build with an USB 2.0 thumb drive on one the USB 2.0 headers, I soon moved on to connecting a legacy external 5 drive enclosure via USB 3.0 and setting the tunable xhci_load = "YES".
I noticed, that this extremely slows down boot of the system, at least. Most of the times the system wouldn't reboot at all. Transfer rates are about 80 MB/s writing. Pulling one of the drives kicks the whole RAIDZ volume, which is built upon those 5 drives.
Nevertheless I bought a mini USB 3.0 thumb drive dd'ed my FreeNAS boot image on it, connected it to the internal USB 3.0 header on the board and removed the USB 2.0 boot drive. I am particular pleased to say, that this works well with the ASRi-2758F! No slow boot (but no faster either!), no problems rebooting. Everything's fine, as far as I can see.
Tomorrow I expect my SanDisk Cruzer Extreme to arrive, which is tested for data rates of 180 MB/s and above. Let's see what can be achieved....
(t.b.c.)
