Crucial M4 256GB Solid State Drive Review

Testing – AS SSD Benchmark
Our final test is the AS SSD Benchmark. This benchmark contains four synthetic as well as three practice tests. It also not only shows you the transfer speeds but also IOPS.

Here we can see that compared to the SandForce-based drives the Samsung drive does not suffer in the write test, it performs right up to spec.

The AS SSD program has a copy benchmark included with it.  This benchmark shows you the speed and how long it would take to load an ISO, Program and Game.  Here are the results from that test, lower scores are better.

AS SSD also has a compression benchmark included.  Here are the results from that test.

The results from this test were very impressive as both the read and write results were almost straight lines, which means the drive would get up to its max speed and stay there.  This test uses random data, so drives that are not SandForce-based really excel here.
