Very interesting but unfortunately slightly off topic
My today's concern is how a recent SSD given for 3000MB/s when plugged on a m.2 PCIE 4x slot of a recent gaming motherboard can be limited to a little 800MB/s, whatever the configuration is , i.e. AHCI or RAID, default drivers or up-to-date ones
To make progress on investigation, it's noticeable that 800MB/s is the faster you can wait of a sata 3 slot, maybe it can serve the mental construction.
To be honest, I thought i faced a very common issue but I now realize it's maybe not the case
PS : I've tried also with PCIE/SATA motherboard power connector plugged or unplugged, it didn't make any difference but it worked in both case :bigeyes::rolleyes::sigh!:
