Upgrading a computer from the old spinning hard drives to a new SSD will make your computer faster. With no spinning disks, the computer will be able to seek your applications and data so much faster. I have also found that this will add new life to your computer and you will get a few more years out of an aging PC.
We have been seeing hard drive failures over the past few months. This makes sense because all of the computers were purchased around the same time. Replacing a drive is a simple process and you should also re-install everything onto the new drive. I never like cloning the drive because you will most likely be pulling over old information that was making your computer run slow in the first place.
One thing to look out for is the connectors for the hard drives. I hope by now that you have SATA cables in your computer. If you have the older cables you can buy adapters to convert the connectors to the new SATA style. Remember to check first before you buy your new SSD drives so you can order connectors if you need them. If you want to upgrade your computer and you are not sure how to do this please reach out to me and I will be able to help.
