HPE held the 2025 HPE Discover Conference in Las Vegas, USA, where a number of new storage products were unveiled.

The most eye-catching was SK Hynix’s new HBM4 memory product:
This is the industry’s first 16-layer stacked HBM4 memory sample with a capacity of 48GB.

A new specification of 128GB large-capacity notebook memory bar (LPDDR5x-7500).
