Copying from HDD to HDD, should be faster than this right?

I've just setup and installed a two disk RAID0 array and was copying over my digital photos to start using Lightroom again. I had them on my backup drive another SATA internal drive (a 1TB WD Green).

All in all the data was about 180Gb and the photographs are all arranged in folders by year->month->date, so there's quite a few folders. All told it took about 45min-1hr to copy across. Is this about right or dreadfully slow?

An hour would mean 50M/s, if there are a large number of files, I wouldn't say that was *too* bad, but windows explorer seems slow to copy most things.

45 minutes would be 68M/s.

To give you an idea, 7GB from SSD to a 500GB mech. HD sees me average around 110M/s (starts off at over 200!) in windows explorer, that is for a single file. If there were lots of files, and lots of data, this figure would go down.

Actually, that makes perfect sense because when I'd benchmarked the WD green drive a few weeks a go it was topping out at about 55Mb/s. Nothing to worry about then!

Copying larger files is always quicker, you should get around 90-110 MB/s with large files, depending on what models you have. 50-70 MB/s for smaller files seems good to me.
