Ubuntu Studio comes as a low latency build with Ardour already installed.
If you can format a hard drive, you can install it. There are easy to follow directions.
I tend to use Linux Live USB Creator to install Linux on remote USB Hard-Drives.
http://www.linuxliveusb.com/ You download the image of Linux that you want (like from
http://UbuntuStudio.org).
Then you install it to a remote hard-drive.
Now, boot to your remote hard drive by restarting your computer and pressing F12. This should bring you to a list of available boot partitions > Windows > USB Drives.
Select your USB Drive.
Next it will ask if you want Regular Ubuntu or Low Latency Ubuntu. Choose Low Latency.
There you go. No more BS about trying to figure out which driver is doing you in. None of them are!!
The last step for the easy path is to use your Class Compliant interface. If you do, there is really no configuration necessary. Just launch Ardour and choose your interface.
If you are using an older interface that has a driver hack, that's tricker and you'll have to do some tricks to get it working.

I'll add that I use a very old and inexpensive and tiny 500 GB USB drive and it works fine beyond 8 tracks which is the most I tend to use it for. Using this drive enables me to use any computer or laptop to make high quality recordings using my RME UCX.
For me, using Ubuntu Studio makes so much sense because it's a low latency build of Ubuntu with everything that's vetted already installed and integrated. It's so super awesome and cool.
Now, the plugins aren't yet up to the level of Sonar plugins, but there are plenty of them. They do cool things too like report sample latency. And there is a meter to let you know how your drive is doing so you know if your drive is a constraint for recording the amount of audio you want to record.
And if anything goes wrong, just format the drive and install the latest version. Piece of cake! Takes less time than installing a Sonar patch.
