jepper, så har seagate gjort det.
With areal density of 6.25TB (Terrabyte) per square inch, 3.5” typical platter would be able to hold up about 49TB of data on one side. Two sides of such platter would handle about 98TB of information. Usually HDDs have from one to five platters inside, the maximum storage capabilities of upcoming HDDs would be up to 490TB, or approximately 0.5 of Petabyte. However, Seagate storage capacity may be limited by about 200TB, as the company does not use more than 2 platters in its HDDs today. HAMR technology will significantly extend the capacity of modern magnetic disc drives that use magnetic heads to read and write digital data onto spinning platters. HAMR achieves higher densities by using a laser-beam or other energy source to heat the recording medium at the same time that data bits are being recorded. HAMR technology will also achieve its high areal densities at a cost structure on pace with the hard disc drives of today, making it a key enabling storage technology that will allow the adoption of mass storage to continue to enter emerging markets.

Det er sq vildt. Men ok, det skulle jo komme, den gamle teknologi som vi bruger i dag understøtter vidst nok ikke mere end 2.5 tb. så det kommer efterhånden på et tørt sted.:)
