Hard drives (IDE, AHCI, NVMe) and why SSD PCIe is the way to go
Ғылым және технология
When looking at hard drives, the protocol (IDE, AHCI or NVMe) needs to be understood to get the right interface (ATA, SATA or PCIe) drive for your system. Today's M.2 Drives can be confusing with all the different keyed interfaces (B Key, M Key and B&M Key). Then to really confuse you, M.2 can be SATA or PCIe - So in this video, I am going to help shed some light on this and make things easier to understand.

Hi Steve, fantastic explanation but I am a little lost on your table. Take the PCIe 3.0x4, it says the transfer rate is 4 GB/s (per-lane) but the bandwidth is 32 Gbps, how did you come up with that number?

GB means Gigabyte, Gb means Gigabit. 1 Byte = 8 Bit, so 4 GB = 32 Gb. At least I think that's what's going on here ^^
Great video. Is there any difference between as pci 3.0 x2 and pci expiress 4.0 ?

Yeah speed of course
My laptop have pcie3x4 slots only and no sata slot. It comes a kingston 512gb nvme drive. The question is in bios I have only two options for hdd interface. 1 ahci 2 intel rst premium with intel optane. Which option should I use in bios for maximum performance from my nvme drive?

use ahci, better for nvme drives
i have a question i got a dell poweredge emc r330 i tried a pci express 4x m.2 nvme connector in the pciexpress slot 8x server woulldnt read the drive in ahci i also tried it in raid and notthing. what can i do to get it to work. beacuse windows seen itt installed to it and server reboots and nothing it dosent see the drive

Maybe put off cmos, like he said in this video at beginning somewhere
I bought a m.2 nvme samsung 970 evo plus and my ahci ports cant detect it. is this a thing? on my bios it says ahci on my port and not nvme... Can I use a NVME disk on a AHCI port??

RAID and AHCI typically only affect SATA drives. They should have no bearing on NVMe drives as those are connected to the PCI-Express bus. There are some NVMe drives that are able to boot on the AHCI bus but why? You bypass the very reason NVMe was released, to deal with inefficiences of SAta connections. At least that is my understanding. There are some boards that will stop NVMe drives from working on AHCI so you need to check your MB specs.
Great for sharing .. but I believe IDE - SATA - NVME are the version you were saying.. cause AHCI is for UEFI..

No that is not correct, SATA is the interface. AHCI is the protocol
