HDD Benchmarking / Iometer

Iometer seems pretty good, it was made by Intel, so it must be fairly good...

Notability because it's on Wikipedia: http://en.wikipedia.org/wiki/Iometer

Open Source because it's on SourceForge: http://iometer.sourceforge.net/

I also came across a similar application which is also open source found here: http://www.iozone.org/

There's loads of other HDD benchmark tools such as CrystalDiskMark and HD tune, but these are only freeware, and not open source, nor are they portable.

With HD Tune in mind I also came across some S.M.A.R.T. tools...

Which lead me to find...

http://smartmontools.sourceforge.net/

It'd be nice to see some of these tools as portable apps, in particular Iometer, the rest are optional.
