The UltraStar He6 is the latest in storage technology by sealing helium (symbol He) into the drive enclosure. This drive is boasting the world’s largest capacity drive at 6 TeraBytes. This was announced by HGST which is a Western Digital subsidiary. It will fit within a standard 3.5″ enclosure.
Technically speaking, they claim that there is less drag on the platters inside the drive enclosure. Helium is has 7 times less density than air. This allowed them to now have 7 platters inside the 3.5″ enclosure instead of the typical 5. Another bonus is lower power consumption indicating these will only draw 5.3 Watts when idle which is about 24 percent lower than typical hard drives. Surprisingly even with the 7 discs inside, it is a bit lighter and tends to run cooler. It will be available in SAS and SATA 6 Gb per second flavours.
You can’t run out to the store and buy one just yet. HGST is targeting more enterprise installations by initially being offered to “cloud and research leaders” who will work with them. As you can imagine, a number of organizations have already jumped on board to test these out.
