Is Disc Recovery slower than Disc Copy?

Post by mhschmieder »

I may have made a mistake in using Disk Utility to do a Disc Recovery of my 6 TB Library drive to me new 10 TB external drive for my new iMac. I let it run overnight and it's barely half done. As the new USB3 drive can perform at 256 MB/s, I suspect that Disc Recovery is a slow operation vs. standard file copying.

Is it safer to do it this way though, regardless of time involved? This is my largest data cache. Next up is Vienna Symphonic Library, which takes around 1.5 TB max but had its own internal SATA drive.

My final copy/clone will be my master drive for project data and personal files, at roughly 1.5 TB, and of course cloning my TM drive (I am hoping I can partition my 2nd 10 TB USB3 external drive to share between Master and TM, but last night my 1st 10 TB USB3 drive wouldn't let me do any partitions).

I seem to recall when I upgraded my TM drive size earlier this year that it took days to copy, doing a straight copy. For Time Machine drive cloning/upgrades, I'm not sure if there is a different strategy that is preferred vs. normal data drive clones/copies.
