CrystalDiskMark V3.0.0h now writes settings to > %localappdata%\CrystalDiskMark30.ini
CrystalDiskMark V2.2.0p writes it's settings (DiskMark.ini) in the apps folder.
V3 is a bit more verbose in the dialog and in copy/clipboard, and a new benchmark was added 4k QD32 (Queue Depth = 32).
Seems to have dropped support for Windows Me/98
V2.2 is still available at their download page
> (Old) CrystalDiskMark 2.2.0p [2010/02/12].
Sidenote: CrystalDiskInfo 3.9.0 released yesterday (10/09/10) still writes it's settings (DiskInfo.ini) in the apps folder.
