I am copying a folder (320 items, 1.9GB) on an SSD to a different location on the same SSD and getting a transfer rate of 5MB/s.
Is this to be expected? Simultaneous reading and writing to the same drive will slow things down, but still - I would guess this rate is slow.
I get these values from HDTune benchmark:
(Read)
Transfer rate: min=12.6 avg=16.4 max=16.8 MB/s
Access time: .300ms
Burst rate: 17.9MB/s
