Western Digital has laid out its plans within the magnetic reminiscence phase over the following 5 years. David Goeckeler and Bob Eulau, the CEO and CFO of Western Digital, have been interviewed by Wells Fargo, and so they divulged a lot info relating to the corporate’s roadmap. For starters, 30 TB HHDs are anticipated to turn out to be out there by 2023, due to the usage of ePMR and SMR applied sciences.
These drives will include thinner plates, permitting for an elevated variety of platters per drive. Mixed with excessive information densities, this may pave the way in which for 30 TB drives within the close to future. Western Digital’s present flagship HDDs, the WD Gold, and Ultrastar DC HC560, each high out at 20 TB. These drives use 9 2.2 TB platters, in tandem with Vitality-assisted Perpendicular Magnetic Recording (ePMR). 22 TB drives could be made potential by including one other platter and using OptiNAND expertise.
Using Shingled Magnetic Recording (SMR) can be wanted to extend capability for customers who’ve a software program stack that optimizes and helps it. SMR and ePMR are collectively anticipated the per plate density by 36%, permitting for 30 TB 3.5″ drives. Using HAMR together with present applied sciences will pave the way in which for 40 TB, and as a lot as 60 TB choices by 2026.
