eMMC to USB adapter "very" slow at reading data

On a side note I'm getting around 50MB/s when dd'ing the data over ssh
(with a 1Gb/s ethernet connection with quite a lot of other traffic, and ssh did not use 100% of one CPU)
sudo dd if=/dev/mmcblk2 | ssh 192.168.9.30 dd of=/dev/null
965813760 bytes (2.0 GB, 1.8 GiB) copied, 37.0941 s, 53.0 MB/s
It seems that piping it through 'gzip -1' and 'zcat' only reduces the thoughput .
So perhaps I should just use the Pinebook Pro (booted of a SD card) as the eMMC reader
