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?

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!
