I am currently in the process of building a new storage server, to be used for virtual machines, files and backup. The OS is FreeNAS, which uses ZFS as software RAID.
My problem is that, I need to choose hard drives and I have looked at both consumer and enterprise hard drives, but i am faced with an unanswered question, which I have not been able to find a clear answer for.
Can I use consumer hard drives, that do not support TLER / ERC / CCTL, with ZFS (software RAID), without getting in trouble later on or do i need to go with enterprise hard drives that supports TLER / ERC / CCTL?
There are a lot of different opinions about this and some say you should use it and some say you should not. I know a couple of OS which relies on software raid, that have their own error correction timeout and therefore does not care if there is TLER / ERC / CCTL. I am aware, that you need to use TLER / ERC / CCTL, when dealing with hardware RAID.
I really hope, that someone can shed some light on my problem.
