Would the external drive be the target drive? Or would you only use it as a "drive in the middle", i.e. copy from source system to external drive, then copy from external drive to target system?

In the latter case, consider copying directly from source to target drive, either via network, or by hooking the target drive up on the source system.
If speed is what you are concerned about, try using SATA, as it is 10 times faster than USB2. You could either connect the target SAT drive directly to the SATA controller of the source system, or you could use an external drive that connects via eSATA. External eSATA drives are cheap, and so are the connectors: http://www.computervideogear.com/sata/external-sata-esata-adapter.htm

Slim pickins' from the question, but if you have this data on a laptop and want to move it to a separate system without slaughtering your network (especially if it's not YOUR network), an external drive is your best bet.  

If you're doing this from desktop to desktop there's no reason to not simply pull the hard disk from the source machine and install it to the target machine then copy the data onto the existing target hard drive.  That will likely be your fastest transfer if your drives are sata or esata.

the data has to temporarily go into a tempstorage and come back to the original drive later on.

I see. Then an external eSATA drive seems best.

On the other hand, you might also consider to simply get another internal SATA, copy data over, remove the second drive and store it at a save place, then reconnect it later. This would give you more space on the server for good.

what windows tools can tell if a disk is SATA or not?

HDTune will do: http://www.hdtune.com/files/hdtune_255.exe

Go to the 'Info' tab and check the "Standard" label in the lower panel. It will say SATA II at the end, if SATA is detected.

hdtunes does not check SAN LUNs, does it?

torimarCommented:
I don't know for sure. Never tried it on one.
But LUNs aren't necessarily equivalent to physical disks.

aren't necessarily, but can be, right?- if each LUN has its own spindles...

torimarCommented:
True.
But may I ask why this is getting so important in regard to the present topic?
I was referring to the replacement drive you are going to use, not the existing ones. If you buy an external drive with a eSATA (eSATA-300) interface connection, you will have much higher transfer speeds than with USB 2 at any rate, independently of the target system's storage setup.

I was asking about LUNs to see if hdtunes can pick them up, to see if they are considered eSATA or not?

thanks for your excellent help. appreciate it. i plan to use a eSATA drive for the purpose, as you recommended.
