IBM uses Everspin MRAM in 5th-gen FlashCore Modules

IBM's fifth-generation FlashCore Modules replace supercapacitors with Everspin MRAM to protect against data loss during power failures. The FCM5 SSDs use QLC NAND with an SLC write zone and come in five raw capacities from 6.6 to 105.6 TB, with effective compressed capacities up to 316.8 TB.
