M.2 PCIe NVMe SSD to USB3.1 Gen 2 Type-C Adapter

    First Impression

The U31M2C is a bridge between the USB host and the storage devices with PCIe/NVMe interface. Its upstream port provides a USB which data speed can reach up to ten gigabits per second (10 Gb/s or 1.2GB/s), or the data transmission rate for USB 3.1 Gen 2 specification.
The U31M2C supports TRIM to the SSD and can transmit and receive data by both of USB Mass Storage Class Bulk-Only Transport (BOT) and USB Attached SCSI Protocol (UASP) to and from the host respectively. The data storage devices can achieve its summit of performance by taking advantage of these built-in unmatched features.

The U31M2C is well equipped for power management that it can meet a wide variety of power requirements from different scales of data storage systems.

Finally, the U31M2C is a new product that almost reaches USB3.1 Gen 2 line bandwidth. Using the U31M2C, the security system can transfer higher quality video, such as 4K or even 8K, and quicker to their data storage devices than ever.
