Finally, I bought a Samsung 970EVO Plus M.2 NVMe SSD. Now I found out that my old mobo doesn't has M.2 key. Any suggestion ? Thanks.
I have an extra PCI slot, would something like this be suitable Silverstone M.2 NVMe SSD NGFF to PCIe x4
UPDATE: Got the adaptor, plus it in my PC recognize it straight away. Do some double check from this post https://www.bios-mods.com/forum/Thread-WORKING-Asus-P8Z77-V-... Turn out my mobo already in Intel Management Engine (ME) Version 8.1. Will clone the OS to new drive and see if I can boot from it. The BIOS from the post is different than mine, so I went to ASUS site and get a latest possible BIOS update.
No success so far …
