To test the real-life performance of a drive we use a mix of folder/file types and by using the FastCopy utility (which gives a time as well as MB/s result) we record the performance of drive reading from & writing to a 256GB Samsung SSD850 PRO.

To get a measure of how much faster PCIe NVMe drives are than standard SATA SSD's we use the same files but transfer to and from a 2TB Kioxia Exceria Plus drive.

The CRAS C925 averaged 1,291.21MB/s when writing the contents of the 14 real-life transfer tests with the fastest being the 2,993MB/s (6 secs) for the 4K Movie Clip folder and the slowest the 296MB/s (182 secs) for the 50GB File folder transfer. Reading the data back the fastest performance came with the 10GB Photo folder transfer at 3,008MB/s (4 secs) with the 50GB file transfer again the slowest, this time at 642MB/s (86 secs).
