Ok, it's a slow drive. If you want better performance, it will depend on your budget and your power requirements.
Not long ago, I put a 500GB Samsung 850 EVO into my Lenovo X140e and it made a huge difference.
If your budget is smaller, you can use a smaller SSD (if it will be big enough for you), or you can get something like a 2.5" WD Black laptop drive. They are 7200RPM and among the fastest mechanical laptop drives available.
