Seagate demos new multi-layer 3D magnetic tech with potential for 240TB capacities

HDDs continue to advance

“By adjusting the laser power and magnetic fields during writing, the FePT layers can be addressed independently, thereby doubling capacity. If that wasn't impressive enough, the researchers reckon this approach can be applied to three-level recording and may even work at four levels.”

These make sense for large cloud storage operations for multi-stage backups at lower speeds and costs.
For raw storage these would be great, but I couldn't imagine using them for any type of random I/O, programs, or OS usage.

From the article... truth!

If so, you'd be looking at a 10-platter hard drive with a rough capacity of about 240TB. Which should just about cover installation of one or two of the latest data-munching games on Steam.

Interesting. I wish SSDs dropped down in price enough to fully replace HDDs. 12TB drives for $250 or so. But it looks like that is still a long ways out.

Imagine how long would that take to fill at SATA speeds? Then think about it in some form of raid, it would take forever to fill and so much longer if one failed and you had to rebuild it.

I’ve got 16TB drives that take at least 12h to rebuild and they are maybe 60% full.

I don’t want to think about 240TB on a SATA interface.
