They're still more expensive, but not by as much as they used to, and the difference is shrinking rapidly. $300 for a decent 1TB SSD vs $60-$100 for a 1TB HDD. And lifespan? Unless you're writing petabytes to them, you're going to be fine. [0] I'm far more concerned about the lifespan of my remaining HDDs.

What now? No, 100mph does not sound fast when talking about the speed of data.
Is there an Internet term for news articles that contain the word "could", similar to those that end in a question mark? Seems like most of them could easily add ", but most likely will not" to the end.
- jws 11y agoI didn't see a reference to the length of the wire. But if we assume 1cm since it fits in a chip, that cycles the entire data through in about 250µS. Not too shabby for mass storage. I'm assume you build a bunch of parallel wires since it is bonded to a piezo electric substrate, I don't think you'd be able to zig zag a long wire back and forth across the plane, the bits would all pile up on one end and… do whatever they do. I suppose a sufficiently clever person might make a drum, wrap it in wire, and send the bits around. I look forward to installing drum memory on a computer in 2025.
