Speeds as advertised for random 4k reads/writes as measured with CrystalDiskMark. I was upgrading the system drive that came with my MSI Apache GE62-6QD. Installation was a breeze once I got the case open. Fortunately, stand-off and mounting screw were present. Make sure you have the latest BIOS to ensure your MB recognizes NVME drives. Both My Ubuntu 16.04 and Win 10 recognized the drive. Migration failed when I tried to restore backups with my paid version of Acronis True Image 2017. Tried Minitool Partition Wizard Free - migrate OS option and it worked first time - very impressive. My only minor complaint is that the management software offered by SP caused my AVG antivirus to freak out when I tried to install it so I didn't bother. The drive does not appear to have a heat sink so if you plan to push it, expect thermal throttling. It works fine for my purposes.
