Solved Can I change the numbers of disks?

Helmut · Jan 11, 2024

The reason maybe that the PCI-E x16 slot is looked at first as that would normally be a Graphics Card, top priority.
Thus putting in a PCI-E Card with NVMe drives, result numero 0.

There should be settings in the BIOS/UEFI to set the priorities of Graphics Cards(PCI-E)/Integrated graphics.

Another thing you can try is put the PCI-E card with NVMe drives in a lower slot, they maybe have less PCI-E lanes allocated but it would prove a point, or not.

I think that's probably right. So here's the first draft of my tentative plan (does that sound like I'm hedgeing?): I can move the OS M.2 to a card, and put the M.2 that's on the PCIe (non-graphics) card on the mobo. And I can switch the PCIe (non-G) card with the graphics PCIe card. That would put the OS disk in the graphics slot, one of the storage disks in the PCIe slot and one of the storage disks on the mobo. I don't care at all about the numbering of the storage disks. Whatcha think?

Maybe you will have better luck than I did, when I did this, it slowed down my M.2 drive on my PCIe card a lot, well according to CrystalDiskMark it did.

As luck goes, I've seemingly got my share and more on W11, so I think I'm gonna try the big switching operation, and if it doesn't do what I hoped, I'll put it all back the way it was. THAT shouldn't foul things up, assuming I do everything correctly. This is all an exercise for tomorrow. It's 8 PM here, and I've had a stressful day, so bedtime is probably 9 tonight, and I'll face these petty challlenges tomorrow, when I'm fresh. Well, as fresh as someone my age ever is. :grrr:

Thanks for your input. 'Night.

Hi,
Yeah my laptop was like that to very annoying seeing the os as disk 1 or 2 depending on which app you use
I just swap slots and 0 is now os in disk management 1 is data.

Disk 0 on my apex is the m.2 slot just above the gpu now os
Dimm_2 card is disk 1 data.

I don't know how the NVMe drives are ordered.

Thanks. I made an early-morning effort to read those two articles, and failed miserably. I think the most likely answer to the problem for me will emerge from the process of physically switching the disks until I achieve the desired result. Appreciate the effort to educate me, though.

But, why would you want to change the numbers? Physically swapping the M.2 NVMe SSDs around is generally not necessary if there is no specific limitation/problem/sacrifice that would somehow be affected by this.

Hi,
Why ask why lol

Wisewiz · Jan 12, 2024

AFAIK, there is no benefit to having any particular numbering of the disks. As I think I said in the OP, I would just LIKE to have the OS on disk 0. Perhaps I’ll just leave well enough alone. As it stands, the OS disk is directly connected to the board, and the two storage disks are on adapter cards. It all seems, so far, to be working perfectly. Explorer file-copying speeds, without FastCopy, are the best I’ve ever seen on any computer I’ve owned.

Chicken lol
No points for being a chicken :lmao:

@ThrashZone

You haven’t given me a single point for anything lately, so being too lazy to switch all these things around (or, if you wish, being too chicken) costs me no points anyway.

You asked question
So you must of wanted to do it but got talked out of by many people asking why blah.... so yeah forum pressure got to you bottom line lol

My OS lives on drive 3. I was briefly irritated (because I foolishly imagined that the universe expected the most important drive to be drive 0), but guess what? Nothing exploded, fell apart or stopped working so I modified my earlier theory of the universe and how all computers must work to include the new paradigm. I have been living happily with drive 3 for the last two years.

Just to prove you wrong about my chicken-livered nature, I went ahead and DID it yesterday! It worked, and now my OS is in the x16 graphics card slot, and it's running between 4 and 6° C cooler, as I suspected it would, up in the air rather than where the M.1 slot is, down under a lot of wires, in a corner. With these SFF cases, there is no fan-driven ventilation to speak of, so I prefer having the least-used disk down under, and the most-used disk up above, on the adapter card. And now I have it. So there!

Hi,
There you go never cave to pressure :thumbsup:

I didn't feel the pressure. I just got tired. And then I got a second wind after a good night's sleep.

BTW, you have this in your specs: 2-WD-sn850x 4tb/ 970evo+500gb/ 980 pro 2tb.

I'd really appreciate your input on my thread about WD SNxxx drives vs. Samsung EVO drives.

WD Black SN770 runs MUCH cooler than Samsung 970 EVO Plus

Recently moved my disks in System 1 around to get my OS disk in a cooler spot (and, as you may have read here, to see whether I could get the OS back on Disk 0). That all worked, and the OS disk idle temp came down from 49-51° C to 42-45° C. But I've been surprised by the temps of my new WD...

That's why when I look at pre-built notebooks in a store, I always ask the clerk whether I can add a disk or disks, and whether I can expand the memory.

Of all of the laptops I have ever owned, I've only had one that I was able to install a second drive in. I miss the old laptops that were easy to open.
