I am running the latest FreeNAS 9.10 with boot mirrored to three MicroSD cards attached via Kingston USB adapters. Over the past two months, I have had three checksum errors (each time only a single checksum error) occur, replacing after each occurrence.
Kingston 8 GB -> replaced with Kingston 8 GB
Kingston 8 GB -> replaced with Samsung 32 GB -> replaced with Samsung 32 GB
Sandisk 16 GB, no errors to date
Now I normally wouldn't question a drive failure, but the sheer number of failures over such a short time frame makes me wonder if something else is awry. Is it possible/probable the problem exists on the USB interface and not the MicroSD cards? I could slowly replace the drives with USB mounted SSDs, but if it's a USB issue I would not want to waste the money.
Additional info: I have no spare SATA ports on the motherboard, but could add a SATA controller if necessary. Unfortunately, this is a non-ECC setup. Prior to the mirrored setup I was running FreeNAS off a single USB mounted flash drive which failed after several years.
Any insight would be appreciated.
