Samsung 850 Pro 128GB SSD Review

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.




The latency results show that with RAPID Mode, the user experience is better across all tests since the latency is less. This occurs when the drive is in a dirty state and after cleanup.


The 850 Pro 128GB on its own has a lot of competition and is only in the mix of other drives and not a clear winner when it comes to user experience. In this capacity size, RAPID Mode saves the 850 Pro and makes it an outstanding performance removed from the herd.


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 disk busy time test shows that with RAPID Mode the 850 Pro 128GB actually has to work harder since the data cached has to be flushed to the drive. This means the drive works longer so it takes longer to get to lower power states.
