Seagate today is talking up the fact that it has managed to cram one terabit (that's one trillion bits, for the record) into a square inch.
That super-dense storage comes thanks to heat-assisted magnetic recording (HAMR) technology, a successor to the perpendicular magnetic recording (PMR) being utilized in current hard drives. The manufacturer sees the technology hitting the market later this decade, "doubl[ing] the storage capacity of today's hard drives" in its wake.
Just how many bits are we talking about here? Let Seagate put things into astronomical perspective:
"The bits within a square inch of disk space, at the new milestone, far outnumber stars in the Milky Way, which astronomers put between 200 billion and 400 billion."
HAMR technology eh? Did PwrHamr know about this?
