Bios doesn’t recognize M.2 on Aspire R15 R5-571TG

Installed a Acer FA100 1TB SSD - M.2 2280 PCIe Gen3 x 4 NVMe, but not showing as a drive in the bios or as a drive in windows. What’s wrong?

The problem that you are having is that the Acer FA100 1TB SSD is an NVMe PCIe 3.0 x4 / NVMe 1.4 and an M end key type M.2 SSD drive type and the Aspire R15 R5-571TG works 100% and utilises its compatible M.2 drives of a B+M end key SATA III 6.0s Gbits/s max type M.2 drive speeds. The B+M M.2 type drives are the most compatible for your laptop but, the M end key type also fits and works on your Aspire R5-571TG-78G8.

The only one example that I know of, is with the Gigabyte 1TB – GP-GSM2NE3100TNTD PCI-Express 3.0 x4 / NVMe 1.3 that works with your laptop as its down gradable and works with a SATA III B+M end key M.2 interface while the Acer FA100 1TB SSD is an NVMe PCIe 3.0 x4 / NVMe 1.4 is not down gradable to a SATA III as that is your problem, also and if you fit this Gigabyte M.2 drive try not to have a 2.5: HDD running inside your laptop and use it as an external drive, as that is what a user of your laptop did and it worked.

Anyway , the Acer FA100 1TB SSD M.2 or the 1TB – GP-GSM2NE3100TNTD drives if they will work will your laptop will never ever utilise their full speeds and really its a waste of a drive as it will always work at a SATA III read/write 6.0s Gbits/s, max read/write speeds. Also update the bios to the last "Updates Intel microcode revision to fix the Spectre security vulnerabilities" dated 2018/10/24 version 1.10 and try that and see if it does anything (which I don't think so). Good luck and hope this helps you out.

These are all the Acer fitted and compatible M.2 drives for your Aspire R5-571TG-78G8 so use these if you can get one as they are cheaper:
