Will there be any noticeable transfer speed increase in using a USB 3.0 enclosure over a a USB 2.0 one with a 3.5" 1TB SATA II HDD?

Yes, most definitely. A typical 1TB SATA hard drive can transfer data at well over 100MByte/sec, but USB 2.0 has a maximum theoretical transfer rate of only 60MByte/sec, and in practice it's limited to less than 40MB/sec. USB 3.0 will allow the drive to tranfer data at full speed.

Keep forgetting that 480MBps is Bits and not Bytes :??:  also, is eSATA hot swappable? I've got an eSATA port on the front of my case (Antec 900 II) which is pluggeg into a SATA port, I'd like to just plug in and pull out a HDD whenever I want just like a USB drive

eSATA is supposed to be hot swappable but it depends on the OS supporting this and recognizing the port as a hot swap port. There is a way in Windows 7 to tweak the registry if it hasn't chosen the right swappable vs. non-swappable type for your ports, see: http://msdn.microsoft.com/en-us/windows/hardware/gg4635...

Yeah I'm using Windows 7 SP1 64bit, but it doesn't matter anyway, found a USB 3.0 & eSATA caddie so I don't think the eSATA thing is going to be much of a problem
