I have a FreeNAS host, which I have had for some years. A fine piece of software. Now on latest stable release 11.2-U7.
Twice in the last 6 months the boot volume has become degraded when one of the USB memory sticks goes bad. Fortunately I notice quickly I have a problem with an email alert. I immediately replace it (time may be of the essence) then the other one fails, and I immediately replace that.
My question is - WHY?? I must be either buying poor quality USB memory devices or there are enough writes to the USB boot volume to wear them out. This last replacement has lasted 3 months. That pretty hopeless.
I have been using Sandisk Cruizer Fit 16GB USB 2.0 flash drives, quite small and from a premium brand - so I thought they would be ok. What does the group recommend for FreeNAS boot drives?
