Meanwhile, Something That Matters

Testing the ioDrive again.  Getting 770MB/s.  On random reads.

Okay, sure, that's with a 128k block size and 4 threads, but it's still close to saturating the PCI-E slot.  At a nice steady 6000 iops.

I wrote a little Python script to generate 240 test cases with a combination of block sizes (512 bytes through 256kb), I/O activity (random or sequential, read, write or mixed), and threads(1, 2, 4 or 8), and I've set 'em off to run and log the results.

I planned to run the same set of tests on a normal drive for comparison.  Then I calculated how long that would take.  Then I quietly abandoned that plan...

Lessee now...  16k blocks, 1 thread gives me 14,877 iops; 2 threads gives me 24,908 iops; 4 threads gives 32,737 (and 524 MB/s throughput).  Shiny.
