The drive is nearly full (copied footage over from the Quiet Tower)…only 13.9 GB remain of 500GB. So the drive is 3% empty. The recommended amount of space to leave for best performance when full is 10%.

At 3% I am still getting read/write speeds of 81MB/s. That is the base speed of my G-Raids when they are about empty. 85MB/s is what I get from them.

81MB/s still gets me 2-3 streams of DVCPRO HD…plenty.
