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.
One of, if not the most important test for a SSD is latency, referred to as access times. The read access time refers to how quickly an action happens after you double click. No one likes to see the Windows hourglass. The Samsung 840 Pro does very well when reading data quickly and the performance is steady across the drive.
I didn't want to clutter my chart with the Samsung 840 Pro 128GB. We found the same issue with this model that we found on the 830 128GB, high write latency. AIDA64 is run after the six tests in HD Tune Pro and the run in HD Tach. The drive was secure erased prior to our test run and given time to recover.
This is our first run, the ninth test in the benchmark cycle. The write latency is all over the place, this look more like a budget JMicron drive than a flagship product from the largest SSD manufacturer in the world.
After a secure erase, we recorded another write latency measurement. As you can see the results were much better. At the end of the benchmark session, we ran the test again and the results were back to the high levels.
We think the Samsung 840 Pro uses a very aggressive background garbage collection scheme that kicks into overdrive very quickly. When background GC is going on the write latency increases. Once the drive has time to clean itself up the write latency goes back to the steady levels. This would be good for RAID users and those working in an environment without TRIM, but users working with large files might find it a bit inconvenient. If you work the drive hard enough, your user experience will suffer.
