RAID ejecting itself while using Premiere CS6
So I recently started a new job working on political advertising and I’ve been working on 12-core Mac Pro with about 64GB of RAM. I’ve been using Premiere Pro, something I havent done in a while, and I’ve been having a lot of trouble with the RAID drive that has everything the company has done on it. It’s a 12TB Mercury Elite Pro Qx2 and currently it only has about 60GB left on it. For some reason this drive has taken to ejecting itself while I use Premiere Pro, whether I’m editing, rendering or even watching something. The only way to get the hard drive back online is by restarting the computer. Also it doesn’t seem to start doing this until later in the day after it’s gotten a fair amount of use. Any ideas?

Yes, it is a bad raid controller and has nothing to do with your NLE. Also you should never let your production drives get more than 80% full. And oh yeah make sure you back everything up ASAP

So what would you suggest? Should I back-up everything on the RAID to another RAID? Also, should I get rid of the faulty RAID altogether or is it still fine to use? Also, with a company that creates a lot of content during each election cycle, what would you recommend for storage solutions?

For backup you either need another RAID of similar capacity, an army of little drives (be sure to double up to protect against drive failure — new drives are as dangerous as two year old drives), or LTO tapes. Be aware that RAID-5 is not a backup solution. It’s redundancy that protects against a drive failure, but it does not protect against a volume failure. It sounds like your drive could be headed down the volume failure route if not sooner then later. Mac OS volumes don’t like hard dismounts.
I would suggest calling the original RAID vendor about your issues. It could be a firmware incompatibility with a Mac OS update, for example. Having your backup in place when you call would be a good practice, as the vendor most certainly won’t guarantee the safety of your data.
As for storage, I would suggest getting ahold of a company with this kind of specialization. Small Tree Communications is a Creative Cow sponsor who installs storage for video editing. Our shop is working with a company called Cutting Edge right now to install a new fiber SAN and Cat DV media management in place of Final Cut Server. We’ll have about 50TB of online storage, 30TB of tier 2 storage, and LTO tapes for deep archive. Deploying a full on SAN is in capital expenditure kind of purchase, but in a sit-down chat one of these firms might be able to assess your workflow and find a cost-effective solution to give you more space and protect your data.

I having this same problem. Just got a new iMac 27″ and have hooked my iStar Raidage Gage (which is housing two 3TB Barracuda 7200rpm drives – mirrored/seen as one 3TB drive) up to it via USB3. Every time I go to render something, the drive is ejected sometime during the render. This never happened when this Raidage unit was connected to my old Mac Pro via eSATA. It doesn’t seem to happen when the iMac is sitting idle, not working in an app. Encoding a file in AME was fine but rendering in AE causes an immediate ejection of the hard disk and rendering in PPro ejected shortly after the render began. It is as if when the drive is being written to, it can’t handle it. I couldn’t even copy a rendered QT from my desktop to the drive via the Finder. ???? 🙁

UPDATE: I am optimistic that my problem was due to a faulty 10′ USB3 cable. I had a 3′ USB3 cable that I have replaced it with (sadly it is too short for my physical setup) and things seem to be working fine. No sporadic disk ejections.
