Hello,
I am in the middle of a salvage operation. Photorec put the estimate for data recovery north of +120 hours on my laptop so I decided to plug both disks into a spare Pi and let it run as long as it needs to.
I know the Pi's USB bus isn't the fastest around but I am concerned over whether the Pi's CPU is going to be a bottleneck or not.
Any thoughts ?
Edit: to clarify, I am salvaging a failed LVM 1TB HDD with a broken XFS partition to an NTFS external HDD. NTFS-3g is CPU intensive but from peeping now and then to TOP it seems to be hovering around 30~40%.
Would using a raspberry be significantly slow ?

Re: Would using a raspberry be significantly slow ?
Update: it took 180 hours to process an undelete operation on the whole disk (out of which 350GB were salvaged). Memory usage was quite low (~45MB at all time) as well as the CPU.
My impression is that the cluster processing and the header detection outweigh the bottleneck of the shared USB bus.
