hi guys,
I was planning to get myself a harddrive upgrade, as i'm running out of space and could use a little more speed.
I was therefore thinking about getting 2 harddisks and putting them into RAID0.
But my question is: Can I, once i've set it up, simply dump all my old data on my new array and keep my old data for back-up?
After all, I can't name it the same so I'm kinda worried all of my programs won't work. of course I could change everything in the register, but that would be quite the effort.
Please keep in mind that is is mostly about my games and programs, I have lots of steam games so re-downloading, installing and patching would take ages. I'm probably going to re-install the OS anyway.(booting times)
Thanks in advance.

First, you can certainly copy what's on an old hard drive to a RAID array. Create a RAID volume, bring the system up. You will see your old hard drive and the new RAID array as a hard drive. Copy files.
However
1) RAID0 is more failure-prone than a single drive, and data recovery with scanning tools is not possible. (FreeDataRecovery, do you perhaps have a way?) If you go this route, backup early and backup often.
2) Copying data is one thing. And you can copy files to the new volume with the same names and directories as on the old volume; the volumes are different and the OS doesn't care.
Copying the OS to migrate to the new drive, if that's what you want to do, is another. If you were copying to a new single drive you could do a "clone" of the hard drive, then boot from the new drive. But with a RAID volume as your boot device, you need additional drivers in the OS installation.
Your results will be anywhere from needing to run a repair installation (simple) to needing to re-install the OS.
3) No, you can't just copy your games to some other location and have them work. You can't re-install the OS and run your previously installed games from the old drive, or from copies in the new drive. The installation process makes entries in the Windows Registry, and may copy files to /windows/system32. There have been many threads on moving game or app directories to another disk to work around space restrictions. I have yet to see a single one that was resolved successfully. You will have to re-install.
And even then, most games will install on your OS volume. Very few apps offer an option to change the location of the installation during the install process.
-----------------------------------------
So. As far as data goes, create a new RAID volume if you want and copy the data to it. Done. I would recommend a new, larger, faster drive instead. RAID is wonderful if you are good at it already, or if you want to play with it to become good and don't care how many times you lose your volumes in the process.
As far as moving your OS to a RAID0 volume goes, and all associated problems, you would need to have the RAID drivers which requires at a minimum an image copy and a repair step, and at most a complete re-install.
If you do a new OS install, you will have to re-install most or all of your applications. Very few apps can be run from app directories that are simply copied to the new drive.
Were I you, and if I needed less than 2 TB total, I'd get a new drive and do an image copy of the old one. If I needed more than 2 TB total, I'd have a separate drive for data (pictures, downloaded music, pr0n). The 2TB limit is because you need a different disk partition system for drives over that size, and a special motherboard to boot from such a drive.
