U.2 SSDs look like 2.5-inch SATA drives — they even share the same general dimensions and mounting screw hole placement, but their connectors are different, and so is their performance.
Unlike SATA drives, U.2 NVMe SSDs interface with your computer’s PCIe bus, enabling them to perform seven times as fast.
How fast? Current PCIe 3.0 U.2 SSDs deliver sustained performance of up to 3500 MB/s read and 3500 MB/s write, or about 7x the performance of the fastest SATA SSDs.
Many U.2 SSDs are now available in capacities up to 16TB — perfect for storing large video projects—with higher capacity models on the horizon. Sonnet’s Fusion Dual U.2 SSD PCIe Card will support bigger SSDs as they become available.
