Do any of you still care about hard disk drives? Blocks & Files has published an overview of what Western Digital presented at its Storage Tech Field Day session on January 22, 2020. Moving to the interesting part, we can see that WD now projects it will be able to hit 50TB (non-shingled) and 60TB (shingled) capacities in 2026.
The application of Shingled Magnetic Recording (SMR), with partially overlapping write tracks, will add a 20 per cent capacity uplift (24TB). After that the roadmap shows a progression with ePMR to about 24TB in 2023 and 30TB with shingling.
Then there’s a jump to 30TB with non-shingled full energy assist – MAMR or HAMR – and 34TB with shingled MAMR or HAMR. From this point the roadmap progresses to 50TB (non-shingled) and 60TB shingled in 2026.
