At the FMS 2024 tech expo, Western Digital introduced its latest solid-state drive (SSD) with a massive 128TB capacity, explaining the technology behind its creation. This advanced SSD is designed primarily for AI operations.
The drive is built on QLC NAND memory and is intended for data centers focused on AI tasks. It features 218-layer BiCS8 chips using a hybrid CMOS directly bonded to Array (CBA) connection. During a demonstration, the SSD showcased a sequential read speed of up to 6320 MB/s and a write speed of up to 3130 MB/s when handling AI processes. According to the manufacturer, the SSD’s firmware is optimized for the overall process efficiency rather than just peak speeds.
The CBA technology works by directly connecting the CMOS semiconductors, responsible for data processing and management, to the NAND array. According to the specifications, BiCS8 memory can communicate with the controller at speeds up to 3600 MT/s.
The SSD is built in a server-grade U.2/U.3 format and is primarily targeted at the business sector. The price for this new drive has not yet been announced by the manufacturer.
