Spinning rust fans reckon we'll have 18TB disk drives in two years
Extra shingled platters spinning inside the helium tank
We could see nine platter helium-filled disk drives because the manufacturers can cram more thinner platters inside a helium-filled enclosure.
According to a TrendsFocus report, current disk platter separator components could be eliminated and enable eight or nine platters to be used in the same 3.5-inch enclosures that currently house seven platters.
The platters could have a slight diameter increase and hold up to around 1.5TB each, using current perpendicular magnetic recording (PMR) tech.
This means a nine platter drive could reach c14TB. Shingled magnetic recording (SMR) could boost that further, possibly by up to 30 per cent.
The report suggests we could see 14TB PMR drives in 2017 and 18TB SMR drives as early as 2018, with 20TB SMR drives arriving by 2020.
On the legend "disks" means platters.
Such nearline drives, it is thought, will appeal more to hyper-scale data centres and cloud service providers than enterprise data centres. ®
