Some use HD Tune HD Tune website
Measures transfer rate (min, max and avg), access time, and burst rate.
Some use HD Speed HD_Speed - www.SteelBytes.com
Measures sustained and burst rates.
Some HD Tach HdTach
Measures read speed and burst rate.
I get drastically different results using each one. These tools just simulate and measure access times mostly I believe, they are not real world speed if you use other techniques like below...
Some apps will show you an average when finished as does Macrium Reflect backup imaging app.
Some, like myself, just copy a large file and measure how long it takes then resort to math! LOL! Or you can cheat and use the Transfer Time Calculator... http://www.pmarks.net/homepage/?page...program=ttcalc
If anyone has other suggestions on tools to measure HDD transfer speeds, etc. please post them here!
