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 2TB Seagate FireCuda 510.

Transfer Details:

• Data file – 100GB.
• File folder – 50GB – 28,523 files.

The EX400U 2TB drive averaged 1,802MB/s for the 9 file transfers in write mode, the fastest being the 2,684MB/s for the 4K folder transfer.
