I have an Areca ARC-1260.
I have created a RAID 5 array 6 * 200 GB, after about 3 years of operation, one of the drives failed, then the entire array failed.
Apparently 4 other drives had bad sectors which become unrecoverable since one drive failed (the controller could no longer use the parity information to recover the data).
Obviously this is quite annoying (to say the least!) since this is an enterprise grade RAID controller (while I bought it mainly for performance, I expected some level of redundancy).
I have received no warning about the bad sectors in the drives whatsoever during the operation (if I had they would have been replaced).
Apparently there is a counter called "Media Error Counter" but there is no warning when it increases.
Areca claims that it would be too "annoying" to receive a notification when it increases.
Ever since, the controller started claiming that drives have failed (no reason why), even new drives, so from my point of view the controller may be fast but it is unreliable which is a critical issue from my point of view.
My question is, which SATA RAID controller has the best error reporting / recovery and is also fast.
