Image/partition is pretty damn simple, and the drive installation is equally easy.
Check out any youtube video for drive installation (shove it in, secure it, hook it into a SATA port, preferably the Blue one because that's SATAIII, but even the SATAII ports will still be fast).
Make sure you have an extra SATA cable.
Open windows, enable the drive in the Disk Manager (lots of websites go through how to do this depending on your windows version).
Run an app like
XXClone for free and do a one-click clone.
Restart your PC, go into your BIOS by pressing either Delete, F1 or F2 during initial boot (depends on your motherboard, I usually just hammer all three alternating if I'm not familiar with the PC), and goto the Boot options, and select your new SSD as the primary boot drive.
Go back into Disk Manager and format your old SSD.
Done!
The easiest thing though is just say ####it and format everythign but your storage drive, and reinstall windows on the new drive. Or alternately, keep your Primary SSD as your windows drive, and just use the new one as fast storage (not a bad option TBH). Then all you need to do is follow the first 3 steps.
