Wireless connect speeds are frequently pretty slow, though those are a bit slower than the 4-5mbytes/sec that you can get with a maximum speed connection.

I'm currently connecting through a G network, are you suggesting getting a N capable wireless router? Thanks!

You should see higher speeds with wireless-n, but you would need more than just an n capable router, you'd need to swap out your g adapters for n ones to see any benefits.

Please note that should, the nature of wireless is that there are no guarantees, your new wireless-n network could perform flawlessly for weeks until a nextdoor neighbor installs his network and the resulting interference trashes your performance - or - you might see absolutely no change in performance - it just depends on the "wireless environment" where you live - or - you might live happily ever after - fairy tale style.

RAID1 is for disk redundancy - NOT data backup - don't confuse the two.

Truthfully, I'm suggesting a wired connection if you're really in a hurry and have large files to transfer.  Failing the ability to use a wired connection, my only suggestion would be patience.  ;D
