Got a slow computer? the problem might be the slow Hard Drive. Upgrading to SSD might solve the problem, it’s one of the steps you can take if your computer is slow, else read the article how to fix your slow computer.
Can you upgrade without having to reinstall the Windows? Not talking about still keeping the Windows OS on your Hard Drive and just adding the SSD, because then, there is no point in upgrading.
The answer to the original question is, yes, it’s possible to upgrade to SSD without losing data or reinstalling Windows OS.
The best, and perhaps the easiest thing you can do is, clone your current Hard Drive to the SSD.
Obviously, your HD would be having a lot of data than the capacity of the SSD, so you can start by moving all the data to another drive, and try keeping only the OS on the drive, or your stuff on the C Drive.
This way you keep the data size on HD as minimal as possible so that it’s easier to clone it to the SSD.
Once you have cloned the OS, you can always move back data to the Hard Drive and keep it connected to the PC and format the OS files ( which would probably be residing in D Drive now)
I have my OS on the SSD and rest of the files are on my older 1TB HD.
If you are using a Laptop, you will face some decision-making issues, like whether to buy an SSD with a larger capacity or buy an External Hard Drive since there will be no option to connect two Drives like there is in the Desktop PC.
I’ve also got a 1TB External HD which is pretty cool, and it is readable on both PC and Mac.
You can use any Data Backup Software that has Cloning feature, like this one
