A:Answer Thank you for the question. A gigabit is a gigabit, whether it's stored on an SSD or a mechanical hard drive. The difference is what you've already mentioned about SSDs - speed, reliability, efficiency. If you need more storage space, you can switch out the existing SSD for one of more capacity, or use an external drive connected via USB. If your old SSD is form factor M.2, PCIe®, NVMe™ protocol, it's possible that you could use it in the HP 17-cn2083dx. You will benefit from a consultation with Geek Squad to determine what solution will work for you.
