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 cache fills. This usually happens only with controllers manufactured by Jmicron.
SanDisk still uses 64Gb page sizes so the latency is very close to the latency we scored with SanDisk's 24nm flash when reading data.
The write latency is a little higher on the X210 than what we scored with Extreme II. The CPU resource pie is only so large and when you dedicate more resources to one task, you need to remove resources from others. SanDisk moved some resources over to checking date integrity and we suspect the checks and the resources led to the higher latency. As you can see, the write latency is still very good, it's just a little higher.
