In March 2023, we reported thatPure Storage planned to sell 300TB SSDswithin three years.
300TB and beyond
Rosemarin highlighted three main issues with using more DRAM.
Firstly, DRAM fails more frequently than NAND.
Secondly, DRAM is significantly more expensive.
Lastly, DRAM’s energy efficiency is much lower, leading to higher energy consumption.
It allows incoming data to be written to different physical flash pages regardless of the intended logical block.
The DRAM holds the FTL mappings and metadata for this process, making it crucial for SSD operation.
Instead, the FTL is done at the system-wide level in Pures controller and its software.
This method, Pure claims, DFMs to increase capacity much faster than off-the-shelf SSDs.
Thats just the start.
It wont be cheap of course.
Last year, the firm said the price-per-gigabyte of its 300TB drive would be less than $0.15/GB.
