This was merely a test using the diskspeed program and instructions included in the SFS package. Like most benchmarks, the results don't necessarily show the full picture.
BTW, this is on the CSMK3, which should theoretically be able of more. (If I'm to believe other's benchmarks)

Luckily, I've never run SFSSalv on any of my large partitions. I tried on my old SYS: but it couldn't/wouldn't fix it so I just reformatted and restarted.
