I'm noticing that while doing a huge data transfer (backing up old HDD data) that my entire computer gets pretty sluggish. These are non OS drives so I wonder why this could be?

How much MB/s transfer rate do you have when copying from old drive? And how old is the old drive?

You may still have certain overhead when transferring from drive to drive. Also note that many virus scanners will be scanning on the fly.

let's do some basics first to make sure nothing is in the way with any solutions we try to provide

Download and run SPECCY, copy and paste the first tab to show your Specs

How is this old drive 'connected' as compared to the target drive; is it USB2 ext drive to a internal drive?

Remove whatever AV your using and go to www.filehippo.com and download Comodo or AVG (AVAST! been hacked so I don't recommend them anymore) and do a full system scan - this repeatedly has resolved alot of people issue relying on MS Essentials and Norton tends to get in the way of alot of programs it seems.
Download Malwarebytes do a full system scan (AV doesn't pick up alot of malware) - this resolved almost ALL other similiar posts to date as most had Malware the AV didn't pick up.
Repeat the AV/Malware scans till the system comes up clean.

Did you install all Windows Updates? Including options except BING? Check them and repeat till ALL are installed.
Download and run Slim Drivers, install all the latest updates but you don't need to reboot until you do the last update. Many times there is some minor Intel I/O driver that never was updated and was running poorly.

Let us know the results of all these steps, 90% of the time just these steps along resolves ALL the issues.

This is on Linux (Xubuntu) which is very light for processing and on a fast machine (new i7 4770S) with 2 new 64MB Cache 1 - 7200 RPM and 1- 5400 SATA drives doing the transferring. Speeds varied from in the kB/s range up to 150MB/s range as it went through files.

I was transfering an entire old Win XP hard drive with the OS.

Many small files will kill speed as well.

drive cache has very little impact on constant file copying.

I am not 100% sure what would kill the speed unless the drive is having issues and your system is trying real hard to read it. I know under Windows a drive having issues can kind of hang(more of a pause than a hang i guess) or slow down the controller it is connected to.

Yes Nuke. Actually in the Win 7 boot, it was at least as bad of a near hang (more drag like you mention). Also it didn't show any progress with file transfer. That's part of why I chose to do it in Ubuntu.

I've had Windows get stuck before and miss files. Seems like file transfer in Linux is a little more dependable.
