I just swapped my HDD for an SSD in my desktop today, and it's wild what a difference it made.
To be fair though, the old hard drive was ten years old and really struggling...
For sure, you'll also notice how much more reliable the SSD is compared to the old drive, being a device that uses Solid-State technology, an SSD drive doesn't suffer from the same mechanical wear and tear that a conventional HDD does, so it should last a very long time.
