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.

Intel's Optane DC P4800X handled our real life file transfer tests without any problems. It dealt with the larger file sizes much more efficiently than the small bity files in the 60GB Steam, 50GB File and 10GB Audio folders.

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 SATA drive out of the picture gives an idea of how fast the drive is when dealing with our real life file transfer tests – although as with the previous test, the performance drops considerably when dealing with smaller file sizes.
