AIDA64 offers several different benchmarks for testing and optimizing your system or network. The Random Access test is one of very few if not only that will measure hard drives random access times in hundredths of milliseconds as oppose to tens of milliseconds.
Drives with only one or two tests displayed in the write test mean that they have failed the test and their Maximum and possibly their Average Scores were very high after the cached fills. This usually happens only with controllers manufactured by JMicron and Toshiba.
Crucial listed lower latency on their white paper discussing the new firmware and it would appear they've done a really good job. Our 512GB drive produced a nice graph with a solid line at .08ms.
The write latency increased with the 256GB and 128GB m4 drives (we had data on them prior to the update). The C300 from last year had a higher write latency when compared to SandForce drives as well. The higher write latency just seems to come natural from the Marvell controllers, but the numbers are still much lower than mechanical platter drives.
