This should be fun - napalm is so engaging!
I don't think AS SSD is the best all around bench - but it is easy.
AS SSD seems to give a lot of credit to cache and gives MFT huge scores.
Running iometer just for 1 minute shows what the drives (w/o cache can do).
Below is AS SSD with acard 4xR0 on 1680ix-12 (no MFT) and then Napalm's favorite - iometer - again acard 4xR0 on ich10r -
