My question is this. Given they cost about $20 more, from what I've found anyway, is it worth it? Is there a downside to this new set of heads being added? I'm thinking a higher failure rate, more risk to data or something like that. I think this is a fairly new thing, last couple years or so maybe. We all know how some new things don't work out.
I think this technology has actually been out for a long time. I'm sure I've heard of it ages ago.
Thing is, it's probably one of those things that's been available in high-end drives for years, but the cost-benefit ratio has been low so few people bought them. Now presumably the economics have changed.
If the actuators are mounted opposite each other, then they can't collide, and presumably can operate completely independent of each other. The costs of two of them were presumably just deemed not worth it.
An opposite niche (and rather apposite for you) was when I started buying disk drives. I think my first was a 2GB Bigfoot, followed by a 6GB, and I bought several 18GBs for work. They were "old tech", 5.25" 5200rpm in an era of 3.5" 7500rpm, but their capacities were huge and cheap. If all you wanted was storage, they were great. Most people thought the size and speed of the smaller drives was better value, even if it cost more per meg.
