The source device is an internal SATA II SSD. hdparm says that it is able to achieve an uncached read speed of about 80 MB/sec, which is close to the limit of the SATA II bridge, I would imagine. That speed is fine.
The destination device is a USB-attached HDD (SATA II in USB 2.0 enclosure). When the destination disk is installed internally (temporarily for testing purposes!) hdparm says that it is able to achieve an uncached read speed of about 80 MB/sec. When the disk is attached via USB hdparm says that it is able to achieve an uncached read speed of about 26 MB/sec.
The dd command is
Code: Select all
dd if=sdx of=sdy
Is this some artifact of the dd command?
In case anyone is interested, the resulting disk is bootable and mountable - but not on the original fitPC. I think that might have something to do with conflicting UUIDs. Yeah, I know I could use tune2fs to change the UUID after the copy. I haven't tried that though.
