Update:
We got the system up and running a 6 disk ZFS raidZ-2 which can have up to 2 drives fail and still function. Curiously upon filling the array up with 3+ TB of data, 2 drives failed. ZFS worked great and there was no data loss even with the 2 failed drives (if one more drive fails a bunch of data is going to be lost). Both errant drives were checked out in a second computer and verified to be bad. One does not stay spun up and is not recognized at all, the other drops out with errors.
NewEgg claims that the bad drives have a 3 year warranty but Samsung claims the drives were sold as is with no warranty (code 101 - OEM comes up if you enter the serial number into their warranty checker).
I've made several calls to both NewEgg and Samsung over the past 3 days and have yet get permission to RMA the drives.

Hello All
I’ve made the decision to switch my storage server from FreeNAS to Solaris. I opted to use FreeNAS as it has ZFS and until BTRFS is stable, it’s the best option (IMHO) for backup and network storage.
The switch was facilitated by the USB stick that FreeNAS was on got lost during a... (1 Reply)
