but to make sure, I tried using dd to have a better measurement: $ sudo dd if=/dev/zero of="/media/mostafa/Transcend2/largefile" bs=1M count=10 10+0 records in 10+0 records out 10485760 bytes (10 MB, 10 MiB) copied, 15.6461 s, 670 kB/s > And the card reader is resetting every 30 seconds.

I also noticed something in my dmesg log: [ 1.173522] ehci-pci 0000:00:1a.7: cache line size of 32 is not supported can this be the reason?
