Slow raw recovery.

I'm recovering data from NTFS partitions in raw mode.
Is it normal that it takes out extremely slowly? Within five hours it has been scaned only 20M sectors (whole drive 3900 M sectors)
The HDD is ok.

There is no error in the SMART. Binary copy speed is about 15-35 MB/s into the file. Also to slow.

I lost my patience. After 2 days scanned Data Extractor scanned only 600M sectors.
For comparison PhotoRec in 8 hours passed 55% of the disk i.e. about 1 TB.
Where is the problem with the DE?

PhotoRec is running at 38 MB/s whereas DE is achieving less than 2 MB/s. Is it possible that DE is stuck in PIO mode?
