When I decided to set up local storage drives at home with a Synology NAS1 (for network-attached storage), I realized Dropbox finally released a feature I've been waiting for for years: adding storage space to your plan.
My Dropbox Essentials plan allows me to increase my storage quota by multiples of 1TB at $63.62/year each.2 If you are on a yearly plan, you get charged for the extra space for the remainder of the billing period, and, supposedly, they don't guarantee you'll get refunded if you decrease the quota—but I think they would if you downgrade.3 The gist is that you can increase your quota whenever you run out of space. My 3TB plan was capped at 4TB by adding one extra terabyte, and that was it. And it took Dropbox years to enable this feature to get more space in their paid plans. (I'm unsure whether this add-on is available in the Family plan.)
I don't know what took them so long, as I think many people will add terabytes to their accounts and will pay them more.
It is convenient, but late for me. I'm running in the opposite direction, trying to rely less on the cloud to store my data.
I got the Synology DS923+, a NAS with four bays that can be extended up to nine bays with two 12TB Seagate Ironwolf drives for redundancy. Kudos to Rafa Roa for the recommendation. ↩
Storage Space (quantity 1). $59.88 / year. Adds 1 TB of storage space. Purchasable up to 1,000 TB. Read more on Dropbox's help page. ↩
The fine print reads, "If you cancel, previous charges won't be refunded unless it's legally required." ↩
