HelioSeal technology

Data centers face increasing pressure. The amount of data is growing, operating costs are rising, but the budget remains the same. Reducing the total cost of ownership has become a focus for data center architects. Therefore, Western Digital developed HelioSeal technology. This hermetically seals the drive and replaces the air inside with helium, which has 1/7 the density of air and allows for a dramatic increase in efficiency and reliability.
