Overview
The Union Memory UH812a is a PCIe 5.0 enterprise SSD positioned as the company's benchmark data-centre product: 14,900 MB/s sequential read, 10,500 MB/s write and 3,500K / 520K random IOPS, sized for the storage leg of large-model training pipelines.
Union Memory publishes the same drive's stability across Oracle, virtualisation and VDI workloads as the buying argument — sustained, predictable latency rather than peak benchmark numbers — which is what a training data loader or a database needs from its flash tier.
