Corsair Force F40 CSSD-F40GB2 review

Can a small drive with great speed hit the SSD sweet spot?

TODO alt text

Mimicking real-world SSD workloads in benchmarks is tricky. Certainly, performance metrics such as sequential read and write tests only tell part of the story. Arguably, the most interesting synthetic test is the 4k random write part of the AS SSD benchmark.

While you wouldn't expect day-to-day performance to precisely mirror the 4k random write results shown here, they do provide an insight into how an SSD stands up to the sort of choppy data traffic that makes up the bulk of disk activity.
