SSD memory is fast. Really fast. It’s also much more stable than spinning drives are, making it pretty desirable for those who want reliable performance from their external drive or on-board memory (and who doesn’t?!). The limited offerings for SSD haven’t yet brought it to the mainstream bulk storage front, but a new technology just might do that. Pioneered by Toshiba and Intel, 3D NAND stacks SSD memory chips to allow for more memory in tighter spots? Early results have given us a 10TB SSD.
