Need advice before selling my FreeNAS build

[sh4dow1234]

Just want start off by saying hello. First time posting here. I apologize if this has been discussed or posted somewhere else but I need some advice before selling my nas server. It has x5 6TB Red Drives with encryption enabled. The storage pool does have sensitive data so i am deciding whether or not to run DBAN on each drive just to make sure the data is destroyed before selling. This can be very time consuming.

Question
Do you necessarily need to run DBAN on it or can I just sell them as is by deleting or destroying the pool? They cant do anything without the encryption key anyway right?

Thanks

Export the pool, mark disks as new, and keep (or wipe, or destroy) the boot device. Your data will be secure.

OK Thanks for the advice.
