Very poor average bench

The ST1000LM 048-2E7172 1TB averaged 72.6% lower than the peak scores attained by the group leaders. This isn't a great result which indicates that there are much faster alternatives on the comparison list.


Avg. 4K Random Write Speed 4.57MB/s
Avg. Sustained Write Speed 37.5MB/s

Unknown consistency

There are too few samples to reasonably determine how consistently this USB perfroms. This result should be interpreted with caution.


Avg. 4K Random Read Speed 1.17MB/s
