Review on High-Performance KingSpec 1TB M.2 2242 NVMe PCIe SSD - Internal Solid State Drive for Ultrabooks by Jerry Peebler

Overall: Impressive SpeedFirst Impressed only since I got the unit a few weeks later. Pros: Used as a boot drive. It uses a SM2263/SM2263XT controller with 2400MB/s read and 1700MB/s write. It uses standard NVMe 1.3 with PCIe 3.0 x 4 down transfer mode, compatible with PCIe 2.0 x 4. Easily spotted on my Asus 970 PRO/AURA motherboard. The current test (Seq Q32TI) shows a read speed of 1474 MB/s and a write speed of 1190 MB/s with a new Windows 10 64-bit operating system installed. With all programs installed, a read speed of 1414 MB/s and a was tested Write speed of 1191 MB/s. Cons: This may not be the case as the reasons may lie with the manufacturer of the MB. Disk numbering in Disk Management is incorrect. However, this does not affect the download process. Some manufacturer software such as AI SUITE 3 and AURA may affect read/write access (significant reduction observed). Attached is the last test performed with CrystalDiskMark 6.0. Update: After the update to KB4100403 there is a speed increase up to 4KiB (8Q8T). The sequential test beat the controller rating. See second picture.
