SSD Capacities Set To Surge As Industry Eyes 128 TB Drives
Blocks&Files, Friday, August 16th, 2024
Maximum SSD capacity is expected to double from its current 61.44 TB maximum by mid-2025, giving us 122 TB and even 128 TB drives, with the prospect of exabyte-capacity racks.
Five suppliers have discussed and/or demonstrated prototypes of 100-plus TB capacity SSDs recently.
Western Digital demonstrated a 128 TB SSD at FMS 2024 in Santa Clara, California, this month. It uses WD and Kioxia's BiCS8 technology with 218-layers and QLC format cells. We anticipate WD productizing this as a successor to its current Ultrastar DC SN655, with its 3.84 TB to 61.44 TB capacity range, PCIe gen 4 interface, and BiCS5 112-layer TLC NAND technology.
