Total Access Time
The access time test measures the total latency across all 18 tests. This is one of, if not the most important test we run at this time for consumer SSDs. When your latency is low your computer feels fast, it's just that simple.
More important than the throughput results on the previous page, the latency tests give us a better understanding as to what each drive feels like in your system. In this test, we're looking for the lowest bar as it represents lower total latency.
This is an area where the OCZ drives do very well, and deliver latency numbers very close to the SanDisk Extreme products.
Disk Busy Time
In the final test, we measure the amount of time the drive worked to read and write the data to complete the test. When a drive is active, it uses more power so the faster it can complete the tasks the faster it can fall into a low power state.
There are many factors that lead to a drive consuming power, but disk busy time is one of them. The longer a drive has to work to complete a task, the more power it consumes. We'll talk more about power consumption on the next page.
