Which type of M.2 SSD does my motherboard support?
Hello
I have combed over my pdf manual but with no specifications on the type of M.2 SSD for my OptiPlex 7040SFF. The manual mentions a SSD M.2 22x80 socket3 and I want to purchase the right kind of SSD. Is this an M.2 SATA (600mb/s) or M.2 NVMe (2300MB/s)?
Service Tag:
Thanks for your help.

Crucial shows both an M.2 SATA SSD and an NVME/PCIe SSD as compatible to a maximum of 1 TB storage. Needless to say the NVME drive would be much faster so consider that drive.

Samsung EVO 960 NVMe M.2 for my OptiPlex 7040 SFF ....
New Generation is PCie 4.0
Samsung 980 PRO 1 TB PCIe 4.0 (bis zu 7.000 MB/s) NVMe M.2
The 7040 does not support the full new speed , because we have PCie 3
Samsung 970 PRO 1 TB PCIe 3.0 (bis zu 3.500 MB/s) NVMe M.2

I found 2 Dell articles that show the M.2 support matrix for various OptiPlex models and my system has a M.2 socket that uses PCIe x 4 lanes. Another good article in the KB has M.2 keys and its common uses.

The size matters and the 7040 comes in Tower all the way to Micro.
NVME PCI-E is likely what they use. Sata might be a problem.

When installing an M.2 SSD hard drive in the OptiPlex 3050, the drive must use the PCIe bus instead of SATA. The following image (Figure 1) provides a visual reference for the two formats:

M keyed only PCI-E version will be the fastest.
Sata is 5X or more slower.

raw speed, not through put, read real bench marks to see truth.

Artificial benchmarks are not "real" they are ways of testing.
600 Meg Sata 3 is never going to be as fast as 3D XPoint aka PCI-E NVME 3000 meg NVME

It DOES boot in seconds but it DOES NOT make your machine many times faster for most things.
My reason for using SSD's is mostly for durability from dropping in laptops. Long term storage is still Hard Drives for my data.

It's hard for me to believe that an SSD works faster for boot times, then slows down to HDD speeds for everything else.

"SSD works faster for boot times, then slows down to HDD speeds for everything else"
This is NOT what I'm saying.
The "SPEED" issue is the same as adding faster RAM to your PC.
XMP ram DOES NOT allow your system to overclock or run faster if your BIOS and CPU do not support overclocking.
SSD's do make your laptop more durable and less prone to dying if you drop it. They do not make your machine faster for most games for example.

Sata SSD's are slower than PCI-E SSD's and always will be. The issue is that when you use your hard drive its not getting the data from the drive all the time. Once the OS is booted or the program is loaded into ram there is not a lot of drive access. Because of this Applications like games DO NOT GET many more FPS aka it is faster but its hard for your eyes to see much more than 30FPS. Things are faster but not 10 to 20 times faster for rendering video etc. Game performance is more tied to GPU rather than CPU because that is what is churning the visual data.
This is also why people are fooled by the Mhz Myth.
2.5 vs 3.0 vs 4.0 Ghz is faster but not 100 percent or more faster.
2 cores vs 4 cores vs 6 cores vs 20 cores can help but only if the software uses them. 4 cores is not 300 percent faster. Each core adds a bit like 6 percent then 3.5 percent then 1.7 percent and so on. Its measureable but not orders of magnitude faster.

hi. sorry to interfere here. Are you using an ssd nvme in the end? i am in the same situation optiplex 7040 SFF, bought a kingston a2000 nvme and even in BIOS doesn't show.
Fresh installed windows 10, new bios 1.18.1 , installed driver Intel-Rapid-Storage-Technology-Driver-and-Management_2PMT8_WIN_16.8.3.1004_A06 and still doesn't show.
i am angry, desperate and feel also stupid...
what can i do anymore...?

Here's another great site for comparing Dell configurations to others and other years of same model.
