From my original post, here is my drive configuration..
( There is a 2nd SATA 200GB (ST3200822AS)internal drive that I have been capturing to for 8 months with no problem at SDI 10Bit Uncompressed from my digibeta deck. I pulled that 200GB drive and replaced it with a 500GB 7200 16MB Cache Segate (ST3500641AS). With the 500GB drive it immediatly started dropping frames on capture. So I benchmarked the drives and the 500GB was a MB or two slower than the 200GB so I bought another 500GB drive and Raid 0’d them together using the SwiftData 200 kit from transintl.com. This config tests out at about 90MB/sec read, and over 100MB/sec write, and still I get the dropped frames problem. Can anyone help? Please? I am starting to have to capture 128Min at a time and the 200GB drive just isn’t large enough to hold it. )
The internal SATA card that comes with the SwiftData kit is a FirmTek SeriTek/1V4 that gives you 4 internal ports.
As far as editing, I have been doing edit jobs on it, for 8 or 9 months now I guess, with just the 200GB drive, and I have just never really run into any problems. I know it doesn’t make sense, it doesn’t to me, but before I ran into this problem with the 500GB drives I had never really researched the requirements. The system was originally bought mainly to do DVD’s on, but due to a shortage of machines to work on and our workload, I was forced to do cut a bunch of spots on it, and some longer format stuff also. I have a new Avid Adrenaline going up next week so that will take care of some of strain on our final cut machine, but I would like to have it function the way it theoretically should. I saved the text of the kona test from both the 2 500GB raid 0 and the single 200GB drive but I don’t have them on me, but I will get them off of our final cut machine on monday and post them.

Just as a point of order for some reason, with my aja lo, I am able to capture uncompressed 10bit sdi to a single 200GB sata drive that with the kona tests gets around 45mb/sec. But with my Raid 0 two 500GB drive that tests out over 100mb/sec, I cannot capture. Also I am talking about 90minute captures, which almost fill the 200GB drive. I wish I could figure out why I can’t capture to the raid…

The other strange thing about it, is that I can move the media from my 200GB single drive to the two raid 0 500GB drives and edit 10bit uncompressed with no frame drops at all, but still it drops during capture.

I was trying 10bit uncompressed from the DigiBeta. I have a firmtek internal SATA card with two 500GB Seagate drives Stipped Raid 0. It’s a kit from Transintl.com that allows you to mount up to 3 more internal drives in the G5’s. It’s avg around 100mb/sec according to the kona test thing from aja. I also looked at the graph and text from that test and it does slighly fluctuate, but never more than 10mb/sec or so.

Yea I DID have them as Journaled before (and my 200GB drive that works perfectly is currenlty Journaled) but I did correct that the other day per the AJA “support” site, as well as try several other of their suggestions. I was on the phone with a tech person at AJA today, and they actually pointed me to this site as a place to see if anyone had any suggestions on ways to fix it.

I talked with a guy at AJA today, and he wants to think that it’s just physically something about the drives causing it. I’m not so sure I buy into that though since they are the same brand/speed as my 200GB single drive, that tests at like 40MB/sec and captures perfectly at 10bit uncompressed. And yet I have seen stranger. 🙂
