SSDs may be the trend, but Seagate is moving ahead with their Heat-Assisted Magnetic Recording (HAMR) technology, which is on track to deliver 20TB+ drives by 2019, and to continue thereafter with a forecasted 30 percent CAGR (compound annual growth rate) in data density to achieve 40TB or higher by 2023.
The HAMR technology will continue to evolve, and if all goes according to the ASTC roadmap, take us to drive capacities around 50 Terabytes early next decade. At this point we will have to combine HAMR with bit-patterned media. We call this heated dot magnetic recording (HDMR) and the industry consensus is that 100 Terabyte drives will be possible with this technology in the future.
