New Technique Promises Much Faster Hard Drive Write Speeds

MrSeb writes "Hold onto your hats: Scientists at the University of York, England have completely rewritten the rules of magnetic storage (abstract; full paper paywalled). Instead of switching a magnetic region using a magnetic field (like a hard drive head), the researchers have managed to switch a ferrimagnetic nanoisland using a 60-femtosecond laser. Storing magnetic data using lasers is up to 1,000 times faster than writing to a conventional hard drive (we're talking about gigabytes or terabytes per second) — and the ferrimagnetic nanoislands that store the data are capable of storage densities that are some 15 times greater than existing hard drive platters. Unfortunately the York scientists only detailed writing data with lasers; there's no word on how to read it."

Who cares about reading?

Considering how often I back stuff up, but how rarely I ever use those backups, I'll gladly take 1,000 times faster backups even if it means slower read speeds than we have now. Really, I'ld take that trade-off in a heartbeat.
