This Addonics M2 Flash drive kit turns a regular M2 PCIe or M2 NVMe SSD into a 2.5" U.2 SSD. The drive frame and the connector mimic the exact size and connector location of a 9 mm. 2.5" SATA hard drive. So once the M2 PCIe or NVMe SSD is mounted inside this 2.5" M2 Flash drive, it can be used just like a standard 9 mm 2.5" SATA SSD with the U.2 connector (SFF-8639), same as the standard 2.5" U.2 NVMe SSD. This allows installing the M2 PCIe or NVMe SSD into a drive bay instead of the PCIe slot. The drive can then connect to a SFF-8643 connector in the system via a SFF-8639 to U.2 cable, resulting in a drive with the same high performance as if the M2 PCIe or NVMe SSD is installed into the PCIe slot.
