This is an odd product. The drive, depending on the motherboard, has a dedicated path to the CPU but does not take advantage of the bandwidth afforded to it. This can help avoid a heavily populated south bridge or avoid running two wires to a traditional 2.5" drive. The is literally a shrunk down SSD with none of the speed benefits associated with the form factor.
KeneshNot and "odd" product. Simply a SATA III M.2, rather than the faster NVMe drivers. The SATA III interface I/O is through the SATA bus, while NVMe is piped directly through the PCIe bus (direct, higher bandwidth connection to the CPU in modern chipsets). SATA III is limited to about 0.6 GB/s. PCIe 3.0 x4, which is supported for high end NVMe drives such as the Samsung Evo Pro has a much higher theoretical bandwidth of about 4GB/s. In summary, you get what you pay for. A cheaper SATA III M.2 would be great in external storage or as a non-boot disk (ie, as a "games" disk), allowing you to save a few bucks, but still get a considerable speed advantage over mechanical storage.
