Left side: ASUS GL753VD with a Patriot Hellfire 240GB PCI Express x4 Rev. 3.0, NVMe 1.2, M.2 2280 [ PH240GPM280SSDR ], Notebook's manufacture date: 2016/12 Right side: Some other brand's Core i3 business class notebook with a Samsung 120GB SATA SSD, Notebook's manufacture date: 2009/something (washed out)
Edit: Should also mention that there might be a setting in BIOS that might not be set properly. I think if you have the SSD set to AHCI mode if I recall correctly than it will function at a lower speed. Now before you change the setting you will likely need to set Windows to boot in safe mode for the 1st boot after changing the setting.
Hello U2Desire, I didn't update the firmware but I will. I have Intel rapid storage driver installed. In everyday usage I am perfectly satisfied with both SSD and overall system speed, it's the fastest notebook I had ever, return from sleep mode is almost instantaneous, but sometimes sleep mode f@cks up USB. In BIOS AHCI is the only option available from a drop down menu!!! I would surely be happier if BIOS, drivers and software for this model wouldn't be half-ready after quite a few months from release. POST is taking too long in my opinion (fastboot is on).
