G-Raid 2TB Speed Tests Inconsistent

[bradcerebral]

Been having some issues with a recent batch of G-Raids that we purchased. Specifically Part number: 0G00271
About every other time I test I will get write speeds via AJA system test @ 33 MB/s. (Read Speeds are are consistently about 80 MB/s) This happens consistently on 3 of the 4 brand new drives we bought. I'm thinking this is why we are having capture problems in Avid and FCP.
On other brand new drives (Same Part number: 0G00271) I'm regularly getting Write speeds of 77 MB/s but read speeds @ 61 MB/s

via FW 800
AJA system test Disk Read/Write
Video Frame Size 1920*1080 10Bit
File Size 1.0 GB

I can't seem to find anything that tells me what I SHOULD be getting to determine whether or not I have bad drives. Any info would be great G-Tech! Thanks!

Hi bradcerebral,

Thanks for your post. Could you please do some more testing of the drives for me, I would like you to use a 2GB File Dize and use the Sweep Video Frame Sizes test. Take a screen shot and upload them here. Please let me know if you have any questions.

Regards,
