I've seen this discussed in older threads but am hoping from a more definitive answer since ATTO seems to want to side-step the true facts of their proprietary DVRAID configuration.
I have 2 x G-RAID G-Speed eS Pro SAS drives that I plan to join together with an ATTO R680 for uncompressed HD, 2K, and 4K single-stream color grading.
I've used DVRAID in the past but what I'd really like to know is what the parity is. Can I have 1 drive fail and still operate while a new disk is failing? Is it Sudo-RAID and if a drive fails, I'm hosed until I can restore from backup?
Am I just as well off going with RAID5 at this point.
