HGST-1ES0240, Capacity 46.08 TB

Designed for Software-Defined Storage (SDS) systems, this flash storage platform balances performance with capacity, delivering high IOPS, low latency at up to 184TB capacity.


The 2U24 Flash Storage Platform is a key element of next generation Software-Defined Storage (SDS) systems. It offers performance advantages as well as flexibility to improve compute-to-capacity ratio by decoupling available storage from CPU resources.

Flash Performance

Depending on the type of SSDs and the number of drives installed, the 2U24 Platform can be configured to deliver the performance you need.
