RAID Level recommendation?

[Robotbeat]

Well... You may have errors on any sort of RAID array, or on JBOD disks. It's just that there's nothing you can do about it with RAID 0 or JBOD, besides just going to a backup. I'm pretty sure you can do a volume set verify on any RAID level that has redundancy (RAID 1, 3, 4, 5, 6, 10, etc).

Also, I just found out there's a new update for the SATA-based Areca-controllers (firmware 1.46) that adds support for automated schedule volume check:

This is good news! That means we can add this into all of our customers (besides one using a 3ware card and another using software RAID).

That is what I was thinking, that any RAID level with a parity runs the potential for some problems. The scheduler is nice, but doesn't let you set a day of the week to implement it. Which kinda sucks.

If you can get to the card's CLI (command line interface), you can make a batch script in windows that will scrub automagically using windows' scheduler. Probably a way to do it in linux, too.

Actually, ANY hard drive has the risk of random data corruption.

True, so I suppose that you could look at it as chkdsk /r for Raid setups.
