As soon as I post this I'm going to ensure that my system specs are correct and posted.
I did three copy operations. From an external drive connected via USB 3.0 to a discrete partition of a single drive. The drive being copied to has 138 GB free of 600. The external drive has 123 GB free of 500. Both win defrag and a two third party defrag utils report that the external drive has less than 1% fragmentation while the drive being copied to has more than 50% fragmentation according to one of the third party defraggers but Window says fragmentation is 3% while the other third party defragger reports 6%.
I will run a defrag and see whether that resolves these issues.
Each of them started at 41.5 MB/S
After about 15-20 seconds copy speed plummeted to 11.1 MB/s and fluctuated between 11.1 and single digit MB/s.
Why is this?
How can I curb or curtail this behavior in future?
This may be relevant, but I have noted that pausing the copy operation mid way and unpausing will return the copy operation to the original faster speeds as long as copying is paused for more than 10 secs give or take.
Is there some cache somewhere that I should enlarge?
Thanks in advance for helping me thresh this out.
No pun intended.
