Hey guys. As any of you who saw my post in the Lurkers Lair already know, UPS broke my computer when shipping it to me. If they pony up the money I insured it for, I'll be using it to build a new computer. I already have some of the parts I'll get in mind, so I'm not asking about that at the moment, but rather I wanted to know, if my hard drive still works, and I get a new hard drive and install Windows 7 on it, what would I have to do to transfer all the data from the old hard drive to the new one? I could also possibly install Windows 7 on the old hard drive, but I'd rather not. Could I somehow set up both hard drives to run at the same time and switch between them? I've heard the term Raid used when describing using multiple hard drives at once, what is Raid and could I use it for my situation?
Thanks for answering my questions!
You can add your old hard drive in as a second hard drive. It probably won't run the applications that are installed on it, though; you'll have to reinstall them. But you can use any data files you still have. (Bethesda games, because they are self-contained in their installed folders, are fairly easy to make work without reinstalling. Most other applications aren't.)
RAID is usually just an annoyance, requiring extra effort to install and maintain, offering just a fractional performance boost, and cutting the reliability of your system in half (if either disk drive fails, you're SOL). You have to reinitialize your disks, losing everything on them, to set up RAID initially.
There are two exceptions to the "if you think you might want RAID, you don't" rule:
Server systems that run RAID 1 or RAID 5 to offer high reliability (these systems can continue nonstop even if one disk fails) at a significant cost in performance. Home users don't have much need for these.
SSDs connected in RAID 0. These can be extremely fast, almost twice as fast as a single SSD.
