FusionIO SLC IOdrive Benchmarks

[One_Hertz]

Yes a driver must be installed or nothing sees it.

You are right it seems like all the calculations are done on the main CPU. It has a CPU of its own as well (the sucker gets hot too; 70C while doing 4kb random writes). This is no big deal at lower QD, but at high QD load this is not a very good 'feature' at all. By the way, the CPU is no slouch either - 4.5ghz i7. Slap this on some standard 2.8ghz AMD cpu and run some high QD work and you just might reach CPU bottleneck with the device alone!

You can not exactly compare things by bandwidth cross-queue. It is kind of apples to oranges. Higher QD will always bring higher latencies and more CPU usage.

The device is extremely strong at low QD, especially 1-4. Looking at all the Hiomon traces this is where most of the single user action happens anyway, which is why I am so happy with this toy. For high QD there are most definitely better options.
