Seagate Technology, the world's largest maker of hard disk drives (HDDs), on Monday formally unveiled its first single-platter 500GB HDD. The new drive itself may be a very cost-effective high-capacity storage option for those who need it, but 500GB platters may enable 2TB (about 2000GB) hard drives in the near future, an unprecedented capacity.
Seagate Barracuda 7200.12 sports half-terabyte 3.5" platters with areal density of 329Gb per square inch, which is higher compared to competing offerings. Currently Seagate offers only 500GB, 750GB and 1000GB models, but going forward it can be expected that the company will also release 7200.12-series hard drives with three or four platters to provide 1.5TB or 2.0TB capacities.
