Disk cloning

dd if=/dev/sdX of=/dev/sdY bs=64M status=progress

Beware: Using a small (default) blocksize will reduce performace dramatically

i.e.

• without bs=64M (defaulting to 512B): ~42 MB/s,
• with bs=64M: ~112 MB/s,

Speed

I-tec SATA USB-Cloning station, clone 2,5" SATA disk to 2,5" SSD manually from Laptop:

• 2,5" SATA disk to 2,5" SSD: 51,4 MB/s

Issues

Fix Alternate GPT header not at the end of the disk:

parted -l

And then confirm fixing.
