To test 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.

We use the following folder/file types:

• 100GB data file.
• 60GB ISO image.
• 60GB Steam folder – 29,521 files.
• 50GB File folder – 28,523 files.
• 12GB Movie folder – 24 files (mix of Blu-ray and 4K files).
• 10GB Photo folder – 621 files (mix of png, raw and jpeg images).
• 10GB Audio folder – 1,483 files (mix of mp3 and .flac files).
• 5GB (1.5bn pixel) photo.

The Crucial P1 handled the larger file sizes of our real life file transfers well, apart from when it was reading the 100GB data file where the performance slumped to 191MB/s.

To get a measure of how much faster PCIe NVMe drives are than standard SATA SSDs, we use the same files but transfer to and from a 512GB Toshiba OCZ RD400:

Taking the standard SATA SSD out of the equation, in our real life file transfers using another NVMe drive to transfer the data to and from saw huge jumps in bandwidth performance, particularly when dealing with larger file sizes of some of our tests.
