RAID6 Best?
Im working at a company at the moment who uses an 8TB NAS RAID. It is RAID 6. (We are a video editing company). The data on the RAID is very important, which is why I think they originally went with RAID (for the parity striping etc). However, will this slow everything down> Just reading up about RAID 6 and it apparently doesn’t offer that many advantages, but DOES slow the system down a fair bit because if the amount of algorithms RAID6 needs. What would you guys suggest is the best for an 8TB (8 HDDs) RAID for video editing?
Thanks!😀

It’s essentially identical to a RAID 5, but with greater fault protection – two drives can die, rather than one.
Does it slow it down over Raid 5? yup. Does it provide a higher level of protection for –[Thomas Morter-Laing] “The data on the RAID is very important” – also yes.I’d sleep better at nights with a Raid 5…and really well when it’s a raid 6.
Of course, if the speed hit worries you, you could always measure the speed of the drive to see if it’s significant with your editorial format of choice.

It’s not the Raid 6 configuration that’s the problem Thomas, it’s the fact that it’s NAS (network attached storage). The vast majority of NAS Raids are not fast enough and not suitable for video editing, they are primarily designed to provide safe and inexpensive system-wide backup for general office use. Unless the NAS setup is very fast, or designed soecifically for video editing, the odds of it providing enough throughput for editing even DV would be questionable.

iScsi protocol on ethernet works very good with editing, but most NAS systems don’t work good indeed.
RAID 6 is great, because 2 drives can die, but any RAID can burn down from fire or fall of a table.
You need Backup/archive on 2 physical locations.

To put everything in a device, whatever the protection may have, is CRAZY.
The best solution is RAID 0 and all the media duplicated somewhere else (and not to close).

Is the idea of not backing up (you’ll read everywhere that RAID IS NOT A BACKUP) the crazy part? Then yes.
But a Raid 6? Raid 5 or 6 (or 5+1 or 5+0) is the basis of pretty much every heavy duty SAN at broadcast networks.

[Jeff Greenberg] “Is the idea of not backing up (you’ll read everywhere that RAID IS NOT A BACKUP) the crazy part? Then yes.”
Hi Jeff,
Many people consider that having the media on RAIDs that duplicates the files is enough back-up.
I want my back-ups not just in another machine, but even on another room.[Jeff Greenberg] “But a Raid 6? Raid 5 or 6 (or 5+1 or 5+0) is the basis of pretty much every heavy duty SAN at broadcast networks.”
Sure. That great for big traffic, etc, but for a single editor, RAID-0 is the simplest, the fastest and the cheaper.
