SanDisk Desk Drive 8TB Review

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.

In our real-life file transfer tests the 8TB Desk Drive averaged 413MB/s when in write mode for the 13 transfers with the fastest being the 8K movie folder at 944MB/s (24 secs). When it came to the read transfers the drive averaged 989MB/s, the fastest being the 5GB image at 1,017MB/s. When in read mode six out of the thirteen tests topped the 1GB/s mark with all bar one of the remaining tests (the 50GB file folder) topping the 900MB/s mark.
The drive seemed much more efficient at writing the larger file size tests both than the small bity ones. When it came to reads the drive handled all tests in a pretty consistent way.
