Drobo

Will Drobo allow my network to be hacked after a stupid mistake?

Have I ust made a stupid catastrophic error that may allow someone to hack into my home network? Ihave just sold my 5N2 but forgot to factory reset it to delete all of the data. It contained no drives. Does the actual device contain any important or confidential information? I’m particularly concerned about any app data that may have been retained especially for Resilio Sync.

Thanks for any advice! And yes, it was a stupid mistake that I have never made before nor will I make again.
