Earlier this year the IEEE Roadmap and Systems released a technical roadmap report on Mass Data Storage. I was the co-chair on this activity along with Roger Hoyt which included experts on various storage and non-volatile memory technologies. The report is available forfrom the IEEE. This activity is the continuation of a biannual Mass Storage Roadmap effort that Roger and I lead with iNEMI for many years.
The report covers hard disk drives, magnetic tape, optical disc technology as well as solid state storage. In addition, there is material, correlated with other IRDS roadmaps on non-volatile memory technologies such as magnetic random-access memory , resistive RAM , ferroelectric RAM and phase change memory . There is also a section on the use of DNA for archive storage.
Some highlights from the report follow. Regarding solid state storage, it is dominated by NAND flash, which is currently a $60B market. Alternative technologies such as MRAM, FeRAM, ReRAM and PCM are still more costly per bit but are being used in embedded devices to replace NOR flash and some SRAM . 2024 is a recovery year for all storage and memory technologies after down years in 2022 and 2023 due to excessive inventories acquired during the supply uncertainties of the Pandemic.

Tape is also significantly less expensive per byte of stored data than HDDs. Thus, tape provides a low cost and compact archival storage. Greater than 100TB native capacity cartridges should be available in future generations.
Digital storage demand is increasing and this creates a need for more advanced storage technologies to support a robust digital mass storage hierarchy. The IEEE IRDS Mass Storage Roadmap outlines projections for NAND flash, emerging non-volatile memories, HDDs, magnetic tape, optical recording and DNA storage development.Our community is about connecting people through open and thoughtful conversations.
