RAID Rage II

The Barefeats.com website also makes note of the writing speed difference between Firewire 800 and SATA.
The G5’s have some sort of problem with the Firewire 800 port that hobbles the write speed. Doesn’t matter if it’s a RAID or not. It’s been that way for a while now, and it hasn’t been solved in the newest machines.

Brilliant review.

Will the Firmtek SATA card and enclosure allow for 10bit uncompressed using an AJA I/O box? Especially when using two exclosures striped together?

I’m using a Blackmagic Decklink card so I can’t vouch for the system’s performance with an AJA setup.
But with my 2-drive RAID 90 percent full I got a test reading of a bit more than 90 MB/sec which is supposed to be able to provide about 72 frames/second with 10-bit 4:4:4 NTSC video.
With 4 drives it should handle the load easily.
See test results at barefeats.com to see what an drive system with lots of free space can do.

Keep in mind that testing is just a “best case scenario” when it comes to drive speed. You need to actually run Final Cut Pro with the footage you want to edit with to find out whether or not the drives can actually handle the 4:4:4 footage.
When doing reviews for the Cow I will run speed tests that show enough speed to run 8bit or 10bit uncompressed footage, but then when I actually try to edit, I get dropped frames. So a speed test is a good reference, but that does not automatically guarantee that the drives can actually run any particular footage with Final Cut Pro.

“Good point, Walter!
There’s no substitute for a fully integrated test run to get an accurate idea of how a system will perform.
