Needless to say, SSD is the man at the moment. Let's get down to how to install and transfer your OS.
1. First decision you need make is: install OS fresh or migrate your current system. Install OS refresh is really easy but time consuming, here I take migration path.
2. Back up the data that you don't want to loose. In general, it's pretty safe to migrate your OS to SSD, but you have to prepare for the worst.
3. You might want to clean up your system to save spaces, besides the spaces that your current system takes should be smaller than your SSD size. try Defraggler and CCleaner.
4. Update Chipset Drivers. AMD or Intel
5. Shutdown your PC and install SSD, should be very easy: SATA data cable and SATA power cable.
6. Restart PC, going into BIOS, make sure your IDE is in IACH mode, usually it should be already.
7. Go to buy Paragon Migrate OS to SSD 2.0, it's $20, yes, there are plenty of free ways to do it, but I just find it's worth it to spend $20 to save all the troubles.
8. Run this program, and copy your current system to SSD, it will take less than 10 minutes.
9. Shutdown pc, unplug in your old hard drive, and make sure your SSD is the first choice of starting option.
10. Restart PC, you should have the exactly same system, just much faster now.
