How else are you going to bring up Monero in unrelated discussions about computer hardware?

For my wallets

You should ideally run your own node when using Monero

That's the default setting when setting up a local wallet. It is also more private due to not being dependent on someone else's node.

Still cheaper though. 4TB you are looking at around 3x the price for it in SSD storage. Although I wonder how the power use compares, might be worth factoring in but probably isn't too massive over it's realistic lifespan
