As the tools are proprietary, figuring out what they actually do would 
be difficult.  I must presume they are at least as good as smartctl.


If anyone encounters a drive the passes one but fails they other, please 
document and post.

Bootable CD/USB diagnostics are convenient for general maintenance.


OS-based tools can provide additional features and optimizations for 
that specific OS.

A good benchmark will stress the drive, possibly causing messages to 
dmesg and/or /var/log/* that would be helpful for trouble shooting the 
"slow writes to disk".
