I think vandriver's on the money here. Those drives can do over 70MB/s for large block transfers. Note that when using Time Machine, there's a lot more going on than pure data transfer, so the machine performance itself will play an important part in determining how long it will take. More here.
But, to answer your question, under the Komplett terms, you can return the other two unused drives within 14 days of receipt.
That's a useful article Leo. Maybe I should just keep them and bear with it. I had a couple of other WD disks in the past and they seemed to be a great deal faster. Mind you, my computer is very slow at the moment and is in need of a major overhaul.
Yeah, I think the issue here is most likely the time that the Time Machine software is taking to analyse the files and move them, not the move itself.
Try a test of just copying a large file/ folder over to the WD drive directly via the OS, without using Time Machine and see how long it takes. Work out the MB/s transfer rate. I'm betting it will be a lot faster than the Time Machine backups.
USB 3 is rated for 625 mega bytes per second.Your gigabyte should have been transferred in no time at all.
I'll bow to greater knowledge!That's the max burst transfer rate, I don't think any external drive will manage a sustained transfer much above 100MB/s
Even at 100 MB/S a gigabyte should only take 10 seconds(obvs) not an hour.
I suppose the other thing to mention is that the first Time Machine backup will, by definition, be the longest and thus by persevering now, you are getting the heavy lifting out of the way. Any subsequent backup will be incremental and fast. For what it's worth, I use a Time Capsule for my Time Machine backups and can back up about 10GB's in about 25 minutes over wi-fi.
Leo, I did a transfer test just now. Moved a 26 GB folder to my WD Elements disk in the Finder. It took just over 22 minutes. Maybe that's how I should do my backups!
Looks like I'll just have to live with it.As Tallpaul says, Time Machine should get quicker for future backups as it won't have as much data to analyse and move, but it will always be slow. It all comes down to whether the added functionality in terms of whether that is time you're prepared to spend. Manual backups could be a pain, and you might easily forget to copy some files, restoring might not be quite so straight forward either.
