To strip or not to stripe...
on Mar 9, 2012 at 4:12:48 pm

Trying to prep a G-Tech eS Pro for Avid MC on Mac Pro.
Its a 12TB with 4 drives on a ATTO R680.
Should I partition this to 4 drives first (Disk Utility) then strip as one big drive for speed perf?
We mostly work with RED files into AMA.

If your controller supports raid5 or has a built in raid 0 controller, you are far better off using a dedicated hardware controller than using the CPU to manage your raid.

The G-Tech eS Pro comes in at RAID0.
Isn't the ATTO R680 considered the controller?
Not sure what you mean but letting the CPU manage the RAID?

Some SATA cards do not actually manage raids, and in those cases, you can use Disk Utility to Mirror or Stripe your hard drives. In the case of more complex raid setups, like RAID 5 and 6 you'll need a hardware controller.

That said, I read that the Atto R680 supports RAID 5, and I would recommend RAID 5 over RAID 0. RAID 5 only allows you to use the storage of 3 out of your 4 drives, but the upside is if one of those drives ever die, you just swap out the bad drive, it will rebuild itself and you'll lose nothing. In the case of a RAID 0, if one drive dies you lose everything.

Richard is right. I would just add that what I meant by "CPU manage the RAID" was that if you create a software RAID in DIsk Utility, it will be a software raid managed by the OS and taxing your CPU. It's better to offload the RAID processing to a dedicated raid controller card such as your ATTO. And RAID5 is a significantly better choice if available.

Thanks folks, soon as I get into work I will look into that.
Im not sure if that option is in the ATTO Config Tool, but I will check.

Also consider the speed you need.
Raid 0 is fast but lose one drive and all data is lost. The more drives in the raid the greater the chance one will fail.
RAID 5 offers protection but you lose some capacity and performance suffers unless you have a dedicated RAID card and a good one at that.
