Thanks for getting back to us, @ddw_23.
Yes, you're right. You can store your QuickBooks data file on a solid-state drive (SSD) for best performance.
Also, for additional requirements for Intuit Data Protect in QuickBooks Connected Services offerings, it requires a minimum of 4.0GB of RAM and twice the size of the largest file set to back up + 100MB or twice the size to restore. Its space is only required from the work folder LocalApplicationData+" Intuit\Intuit Data Protect".
For more details, check out the system requirements that I've shared above.
I'm also adding this article to further guide you in managing the growth of your business using QuickBooks: Help Articles. It includes topics about account management, banking, and expenses, to name a few. You can click the + More topics button to view other selections.
If there's anything else you need help with, please reach out to me. I'd be sure to jump in as soon as I can. Thanks for posting and have a great day.
