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 and Toshiba.
If you've ever wondered why 10K platters are important and what they do for your user experience this chart makes it very clear. User experience starts and ends with access times. No one likes to wait for a folder, program or anything else to open after you double click on it. The lower the access time, the faster you get a response. The higher the spindle speed, the lower the delay.
Write access times are a combination of platter speed and DRAM buffer optimization. The new 1TB model is actually a little slower than the older 600GB model in this test. Most likely some changes were made to the algorithms that control the DRAM.
