Other HDD manufacturers may be intent on upping their drives’ maximum capacities by hermetically sealing helium inside, but Seagate’s latest effort achieves exceptional storage space without it.
Whilst sealing helium within a HDD reduces friction and heat, meaning that an additional two platters can be used inside the drive and increase its capacity, Seagate have upped their newest drives capacity by instead increasing the drives areal density. In other words, whilst each square inch of the platters utilised within their drives could previously store 831 bits, this figure has increased to 1,000.
Seagate claim that their latest drive is also 25 per cent faster than drives that use helium and that, thanks to superior rebuild functionality built onto the drives SAS controller, data rebuild times are significantly reduced in the event of a drive error – something that is certain to appeal to data centre owners.
No news has emerged on whether or not Seagate’s latest effort can match helium-filled drives superior power consumption or longer lifespans, however.
