Tape Storage Might Be Computing’s Climate Savior

How much power would it take?

For what I could find, Samsung 970 EVO Plus (1 TB) consumes 40 mW when idle. This means that a 100 TB array would have to spend about 40W on idling, or 350.4 kWh a year.

Even at $0.50 / kWh, it would cost $175, a trivial price to pay for having your data instantly available.

The price per TB is not great though, about $50, while an 45TB LTO9 cartridge is about $110, or $2.44 pet TB.

So it's not the price of the power.

45TB is the 'compressed' capacity, the actual capacity is 18TB for LTO9, for $6.11/TB - still an order of magnitude cheaper than SSD, mind you!
