An increasing variety of motherboards or notebooks are currently available on the market, including motherboards equipped with Intel Z270, X99 and the latest 2 Series/3 Series chipsets, all of which are equipped with the M.2 PCIe interface as standard equipment to enable future upgrades. As long as the M.2 slot is the M key version, a solid-state drive that comes with the M.2 PCIe interface can be employed to push the speed and performance of a computer to higher levels. The KINGMAX M.2 2280 NVMe SSD PJ-3280 (Gen3x2) is manufactured using 3D NAND Flash stacking technology, making it highly efficient, stable and durable. Meanwhile, the M.2 2280 is 22×80 mm in size and is available in capacities of 128GB, 256GB or 512GB, suitable for improving the performance of space-challenged notebooks and ultrabooks while expanding capacity.

The speed of the PCIe Gen3x2 (16Gb/s) interface is inherently much faster than that of SATA III (6Gb/s). The PJ-3280 solid-state drive, which supports the NVMe high-speed transmission interface, features actual reading and writing speeds of 1,600 MB/s and 950 MB/s respectively in its maximum 512GB configuration, which are around twice to 3 times as fast as the reading and writing speeds of an average 2.5-inch SATA III SSD. Therefore, for computer users and e-sports players to whom speed is of paramount importance, solid-state drives with M.2 PCIe interface will be their best solution in the pursuit of speed. The entry-level KINGMAX PJ-3280 will also be the best choice for users who are switching to M.2 PCIe SSDs for the first time.
