I dont expect to need more lanes for this nas. The drives are 12TB each and should me more than i need for what i plan to use them for.

The biggest thing i was hoping to get out of a premade enclosure was lower power draw, but you’re right that I can just get old low power equipment, which should help

I would take a SAS DAS if you know of one.

This is what i was expecting to hear, i was just hopeful someone knew something i didnt.

what model sensors are these? are they Z-wave? how long does the battery last?

I’m very interested in a similar setup.

if you want to type the key yourself each time this could work. I’m not aware of an app that does this but it wouldn’t be too hard I don’t think.

if you’re encrypting at rest you also have to consider where there encryption key is being stored.

if you’re storing the encryption key plaintext on the same drive as the data, there’s not much of a point in encrypting.

a TPM/HSM could solve the issue, depending on how far down the rabbit hole you need to go.

EDIT: You could also encrypt the disk of the VM/Server hosting the app. similar situation.
