Storage Speed Benchmark Using CrystalDiskMark

I have always been an enthusiast in computer hardware benchmark. Lately I been trying to increase my overall PC performance (both laptop and desktop).
A speedy and responsive system does not only take a fast processor, but also enough RAM and good harddrive.
CrystalDiskMark is one of the free benchmarking tool that you can download from http://crystalmark.info.

I have benchmark various storage media with CrystalDiskMark, my hard drives, USB flash drives, SD cards. And the table below will show you the result.
Most of the time my CrystalDiskMark setting is set at max 50MB test and run 3x. CrystalDiskMark will avarage the result
