Fred,
Are you serious? You are really going slam me on a public forum when I’m just trying to be helpful? I’m not sure of your angle here, but if you have an issue, you can man up and call me personally and we can settle this on the phone. If you are in Los Angeles I would be glad to meet you in person as well.

Some raids will allow for this changing of their cycle, however, many are completely unusable during this discharge cycle due to severe performance issues in write through mode. He might be able to contact this vendor and ask how to change the time on the discharge to a weekend (manually)

What RAID are you using? Could you provide background information on your setup?

Alex,
You should surf around this site a bit. I think Mark’s joking sarcasm was lost on you. I would venture to say that most of these forums require a thicker skin… or it’s just that in the written form jokes and banter are often misinterpreted.

I was going to post a block size question but then figured otherwise since with the AJA system you would have seen issues with large frame sizes if your block sizes are off.

lol—– There is a reason Drive Savers has the saying that it’s not the crash that makes recovery difficult, it is the user trying to recover the data first that makes their real recovery difficult.

well… if your RAID is performing perfectly every time you benchmark it, or if you digitize to it and it nails the data rates perfectly… it’s time to look at Nuke.
I know some applications depending on Quicktime as a “render to” option choke out and top at speeds of only 70MB/s even though they are sitting on a SAN capable of 4+GB/s
I don’t know Nuke that well, but from what you are saying I would place my money that is your issue, not the RAID0 array. (granted you feel the RAID is performing optimal outside of this)
What tests have to done with Nuke to know that it absolutely should be performing above and beyond this?

4k frames on an internal 3disk RAID0? That’s crazy talk. Download the AJA data rate calculator and look at what it takes to run uncompressed 4k.
answer: 500MB/s to 1.2GB/s depending on bit depth and misc settings.
4k is the new flavor of the month, but to work with it correctly you need some serious spinning disk, at least in our current technological state.
For compositing you can work with what you’ve got, just don’t expect ANY playback, ever. Also important to note, if you lose a drive or cough a drive temporarily, all your mind numbing hour killing compositing is gone. When I used to do rotoscoping I never worked outside of RAID 3 or 5. I’m pretty sure if I lost a weeks worth of compositing because my raid decided to drop a drive I’d be on a ledge somewhere 🙂

If you are wiping the drives, then maybe you could try to re-RAID the drives. There is no better “defragment” then rebuilding the parity from scratch 🙂

If your SAN Cubes are as old as the G4s… you should really be looking to replace them, and not necessarily by Micronet. I’m fairly sure the builders of those SAN Cubes are long gone by now 🙂
Sounds like the department blew the budget on replacing the computers and left nothing for the storage. If that is true then you are in a tough spot.
I’d say, go out and buy a bunch of firewire 800 1TB boxes, they are at or near 100$ each nowadays, and probably more reliable than a product that is 8-10years old. If you have money, go buy a SAN for your department.
