PCIe Gen 4x4 UD85<br><font color='#888888' size='2%'> </font> Lower Latency With 3D NAND

Lower Latency With 3D NAND

With 3D NAND flash technology, the UD85 incorporates multiple layers of vertically-stacked memory cells to overcome the density limitations of its single-layered 2D counterpart and achieve greater capacities. A reduced distance between memory cells also results in lower latency and higher performance.
