Total Access Time

The access time test measures the total latency across all 18 tests. This is one of the most important tests we run at this time for consumer SSDs. When your latency is low, your computer feels fast; it's just that simple.

Throughput isn't everything. It's always nice to be able to transfer files at 300 MB/s on demand, but having instant action after issuing a command is more important in day-to-day tasks. In the chart above, we see the total latency for each run with all of the tests in each group. The SanDisk Extreme PRO does deviate a great deal and delivers the absolute best user experience of any consumer SSD we've ever tested.

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.

The Extreme PRO manages to move the workload faster than the other drives on the chart. This allows the drive to complete the task and then drop to a lower power state faster. In notebook systems, this can increase the battery life.
