File Copy Speed
We use AS SSD version 1.7.4739.38088 to benchmark the speed of copying different types of files within a single partition the size of the whole SSD. The SSDs are tested in their steady state again.
Copying files within the same SSD is a specific load which requires fast processing of both read and write requests concurrently. In this test, the Crucial M550 series delivers average performance again. It is faster than the Samsung 840 EVO at copying folders with small files but falls behind when copying large files. The 256GB version is an exception again. It is as fast as its larger-capacity cousins in the M550 series, so it is better than the same-capacity Samsung 840 EVO.
