CrystalDiskMark
It's worth remembering that the following benchmarks are conducted with the drives in a used state.
What's telling here is that the F120 is, again, closer in performance to what we'd expect than the F100. Taking all drives into account, the F120 spits out middle-of-the-premium-pack numbers here.
But there's a reason why SandForce-powered drives don't produce stellar results in CrystalDiskMark. Part of the controller's armoury is what's called 'DuraClass' technology, where the controller uses on-the-fly compression to keep noisome write amplification - the bane of SSDs - below a figure of one. Unlike data used by most applications, CrystalDiskMark's large-file tests use data that's not partial to compression, leading to lower-than-expected results.
