This M.2 adapter turns a regular M.2 SSD drive into a U.2
SSD. The drive can then connect to SFF-8643 connector in
the system via a SFF-8639 to U.2 cable, resulting in a drive
with the same performance as it would be if it had been
installed on a PCIe slot.
IOCrest SI-ADA40121 provides the capability to utilize an Intel 750 Series 2.5" NVMe SSD (SFF-8639). Comes with PCIe 3.0 x4 (12 Gbps) bandwidth that can be used if motherboard comes with M.2 M-key slot. Otherwise M.2 adapter will be needed.
