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 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.

The 2.5" U.2 M2 PCIe SSD drive kit is designed to accomodate four different sizes of M2 PCIe SSD. The metal frame has the exact dimensions

Booting from the M2 PCIe or NVMe SSD is a function of the system hardware and BIOS. Users need to check with system manufacturer on the support of this feature.
M2 PCIe SSD is not the same as the M2 SATA SSD. M2 SATA SSD can be installed into this adapter but will not be operable. The M2 PCIe SSD communicates via PCIe BUS and the data throughput depends on the speed of the M2 media and the PCIe BUS. A 4-Lane PCIe 1.0 slot has a maximum speed limit of 10 Gbps whereas a 4-Lane PCIe 3.0 slot supports a maximum speed of 40 Gbps.
