NVMe Slot Specs for Precision 3460 SFF

I have just ordered a Precision 3460 SFF with the 256 NVMe Class 35 SSD in the 2230 slot. I would like to find out whether or not this 2230 slot supports a Gen 4 NVMe or not. I know that the two 2280 slots in this machine support Gen 4 NVMes, but I cannot find any info about the 2230 slot.

Anybody know?

For Precision 3460 M.2 NVMe storage slot number 1 is CPU-bound (using CPU PCIe lanes) - and 12th gen CPUs do support Gen4 and Gen5 PCIe standard natively (incl. some lower versions for backward compatibility).

NVMe M.2 storage slots numbers 2 and 3 are going via PCH/Chipset W680 which supports Gen4 & Gen3 PCIe standards.

If you're planning to create RAID volume from your drives - then it would be slots 2&3 but not slot 1.

There's another M.2 slot (shorter) used for WiFi card (different slot key), NVMe drive can't be plugged there.

As for 22110/2280/2260/2242/2240/2230 - it's just a length which can be adjusted by changing mounting screw. On this motherboard Dell implements 2230 and 2280 standard (just by moving mounting screw) in two NVMe slots (but not the third).

Make sure you buy the right screws because for some reason Dell doesn't include them.

Agreed. I have the correct NVMe M.2 screws. I purchased a pack of a dozen of them plus a sheet of thermal pad for an earlier project. Thanks for your reminder!

Thank you for your very detailed response. I can confirm everything that you say because the machine I ordered just arrived today and it is exactly as you describe. It is nice that all 3 NVMe slots all support the faster Gen 4 NVMe drives!

I am planning to eventually have 3 NVMe drives installed. I will eventually clone and replace the 256GB 2230 Gen 4 boot drive with a larger 2230 length boot drive. Slots 2 and 3 will have 2TB 2280 NVME non-RAID data drives. I have a separate backup device on my LAN.

I am wondering why the Dell documentation, Technical support chat personnel and Sales chat personnel (except for one fellow out of 3) could not confirm this as well. It seems as if Dell's documentation for this machine is dated. Probably because the product is near EOL and they don't want to update?

Anyway, I was pretty sure that it had 3 x NMVe SSD slots because it was possible to order the machine with 3 NVMe drives. The only thing that I couldn't tell was if the 2230 Slot 1 supported Gen 4. You confirmed that and I thank you!
