HGST HelioSeal Technology
Hitachi Global Storage Technologies (HGST)'s HelioSeal Technology hermetically seals the HDD and replaces the air inside with helium, which is one-seventh the density of air. The less-dense atmosphere resets the boundaries and challenges of conventional high-capacity HDDs, allowing for dramatic increases in efficiency, reliability and value. HelioSeal technology complements magnetic recording technologies like shingled magnetic recording (SMR), heat-as- sisted magnetic recording (HAMR) and bit-patterned media (BPM). When paired with SMR, HelioSeal technology will enable the fast-growing cold storage market.
