Hi all,

Is it possible to boot from a nvme ssd plugged into a nvme pcie adapter on the m5a97 r2.0 motherboard? I've been searching online for some time and some people say it is, and others say it isn't. I took a look at Asus's website and didn't find anything relevant. Can someone provide some information on this matter?

Thanks.

Reading through the manual, it says nothing about being able to boot from that NVMe drive in an adapter in that slot.
Meaning it cannot.

That board came out before NVMe drives were a thing. If they had made some update to the BIOS to allow that, it would be referenced somewhere.
It isn't, so it can't.

Unless you can find specific data, in writing with instructions, that says Yes....then No.

Boards of that vintage do not natively speak NVMe. Especially in an adapter in a PCIe slot.


Anyone that states "Yes"...ask them how, exactly.

I skimmed through the motherboard manual, searching for terms such as "boot" and "boot device". Didn't find anything relevant. Where can I find the relevant information in the manual, which section do I search?

But just to double check, it's fine to use a data drive?

I know you know, but the R/W speeds for nvme are around 4 times as much as sata 3. Doesn't this make a difference in real world applications? What are the point/advantages of nvme compared to sata 3?

For some use cases, the R/W speed of the NVMe is vastly faster than SATA III SSD.
Some use cases...like large sequential file movement. Video production, 3D rendering maybe.

The small file data access is not a whole lot faster than SATA III, and both type of drives have near zero latency. That's where SSD's benefit over HDD's.

Real world analogy, cars.
3 cars...a Civic (HDD), Camaro Z28 (SATA III SSD), Corvette (NVMe).

Both the Camaro and Vette are way faster than the Civic.
The Camaro and Vette are both really fast 0-60. Near identical.
The Vette has a much better top speed than the Z28. But that top speed is only seen at the track.
But if you only drive on roads with a 70mph speed limit, you'll never ever get to see that top speed difference.

If all you concentrate on is the Top Speed number, then the Vette advertises much much better, and what people buy into. The typical user never gets to utilize that speed.


HDD-> SSD, huge benefit.
SSD->NVMe, not so much benefit.
