I’m Apple user from the first hour,
what are the alternatives to a 12core mac?
Up to now I didn’t think about it, but perhaps I consider an alternative workstation.
FCP is dead, we switch to avid. So the switch can also mean a new PC based workstation.

Please join in.

cheers

Rainer

yes I think, with the new thunderbolt our world changes.
instead of PCIx we will deal with thunderbolt raids and arrays.
The new mac pro will give us up to 3x4K display ports – interesting.
In case of speed we will see, when its there.

cheers

Bob,

with your picture above and your magic words behind you,
you are the first and truly magician in the holy world of Array and Raid systems.
Take it with humor,
you are right.

cheers

Rainer

At the moment I’m watching “The Legend of the seeker”, forgive me.

So back to Neil,

my recommondation for you is: Send back the OWC stuff, buy a raid enclosure which fits your needs and put some enterprise HDs in it.
Less hustle for years, less problems to think about.

cheers

Bobs comment is exactly what we have encountered over the years:
We have tried to work with Hitachi HDS drives in a raid. The drives worked fine, but we’ve had 4 disc failures in a 16 bay raid within two years. We’ve switched to Hitachi Ultrastars – one disc failure in 3 years but with 64 drives.
For us the only disc we put in a raid array are Ultrastars.
We have made good experiences with some seagate barracudas, built in three La Cie Desktop drives. So the big manufacturers build good storage, and for me I would always recommend enterprise storage in any raid array, because its simply better, more reliable in the end cheaper, because its lifespan is bigger than a desktop drive.

cheers

Hi Neal,

the barracuda drive DM001 (2TB) is in the drive compatability list of sonnet not recommended for Video editing. The 3TB version of the DM001 is not even listed.
For me an alarming signal not using this type of drive in an array system.
cheers

Hi Neal,

interesting. Can you check which hitachi drives have been in the chassis before they switched to barracudas? If the drives have HUA before the serial number, its enterprise class, if they have got HDS before the serial number its desktop drives. The barracudas are good drives – so to me not as good as HUA’s but the same quality than HDS drives.
It could be that the change of the manufacturer (WD is building the HUA drives, Toshiba is building the HDS drives, both still beeing sold as Hitachis) is the reason.
A drive normally fails either at the beginning of its lifespan (first 6 month) or at the end (after 50.000 working hours), there are always things happening out of the row. So if one drive fails at the beginning, there is nothing unusual happening. You will get a replacement.

cheers

Rainer

hi Chris,

For a start: Raid5 level is fine for this type of drive. It has a built-in controller and you can choose between usb, FW and esata.
We use this type of drive arrays just for back-up purposes. It simply doesn’t meet our professional standard. Bob has just mentioned this simple fact.
First of all: What performance do you expect from your Raid system? What do you need it for?
I can tell you my opinion:
A Raid has just one purpose: To work, to work, to work. You have to forget about it, that its there. (Walter Biscardis words are still in my head)
Now, a Raid like the OWC you describe (incl. other brands) doesn’t meet this single truth (your own experience).
The lowest raid, that meet this level is a 8bay SAS raid with enterprise HD’s (Hitachi Ultrastars) Raid 5 level plus one spare.
The best Raid is a 16-24bay FC Raid 4x8GB plus 4x8GB Atto card Raid 6, one spare with Hitachi Ultrastars.
And keep Bob’s words in mind: Go for a good brand (Sonnet, Dulce, Smalltree, active storage etc.) In the end its cheeper.
In case of your failure of the OWC: It sounds like a bad controler or cable.

cheers

Rainer
