I’m not surprised that the 1TB limit has been reached. I’m surprised, rather, that Hitachi’s offering is going to be only ≈$400. As of a couple of weeks ago, Seagate’s 750GB drive was well over $500.
Certainly, perpendicular recording was a breakthrough, but at the same time, I’m still waiting for all the revolutionary technologies we’ve been promised—rather than creeping up by degrees, things like HAMR will very suddenly give people way more storage than they need.
Still….. one terabyte is an awfully big drive for only $400. Though I’d hate to buy it, fill it with data, and have it go south (Hitachi’s got a shaky reputation).
