No other firewire devices when the aja la is connected because I only have the one fw400 port. I am thinking of buying sata card for my g5 to test the array and capturing. This way I can solve the issue but if it does not work then I am out another 100 dollars. Thanks for all the help

It does kinda suck to be beta testing both the express cards and the macbook pro. But you would figure with 120mb capturing 30 should not be an issue. Do you think 2 sata drives should work for 10 bit on a g5?

Thanks

I have done all that more than once and still having issues. I am begining to think it may be a problem with the express card slot on the mac itself maintaining the data rate.

Which program are you using to benchmark the drives? If you are using the kona test suite you may want to check the graph for random drops in the write speed.

Tony,

I have gone through all the reccomendations aja has to offer including calling tech support. Also the drives are not journled but just formatted Mac OS Extended. I think I forgot to mention but the problem only seems to be during capture as I can playback from the timeline fine. I just ran another benchmark using the Kona test suite and it does show some fluctuations down to 80mb per second during write tests. Do you think 2 striped sata drives should work if I put this on a g5? I do not have a sata card in my g5 so I would need to purchase one, but hate to put any more money into the situation if I am not at least somewhat sure it will work:) Any help would be appreciated.

Thanks,
Marc

I forgot to mention but I am only experiencing dropped frames on capture.

I am using the following:

Macbook Pro 2ghz 2gb ram
Firmtek Sata II Express Card
Firmtek 2 drive Sata II Enclosure
2 Maxtor Maxline III Sata Drives with 16mb cache
AJA IO LA

I have benchmarked the drives with a few tools and they benchmark at 122mb per second. However the kona benchmark tools show some drops in writes to about 80mb per second. I am curious if 2 Sata drives are enough for 10 bit uncompressed SD. Any thoughts would be appreciated.

I too am having this same problem but with a macbook using an extermal sata enclosure with 2 drives. My system benchmarks at 120MB but still drops frames.

I have them already on order and shipping 2nd day air:) Hopefully this will eliminate the issue.

Bob I appreciate the input. I think I am going to buy some Sata drives anyway to elimniate at least that as an issue. I am also now experiencing sporatic capture rates even at dvcpro50 resolution so I suspect it could be the firewire 800 card itself.
