Sticking with 512 would work perfectly fine, but you'd be imposing an unnecessary bottleneck and the copy would be a lot slower overall. Whether 10K is optimal or not depends on the exact hardware you're messing with (it looks pretty low to me, I'd suggest more like 1M). ______________________________________ it has a certain smooth-brained appeal
