Question What is the difference between Asus Hyper M.2 x16 V2 and Hyper M.2 x16 Gen 4 ?

[Sudecka80]

Implementation will be Lenovo ThinkStation P520 and P720. (RAID 10 setup)
Both Intel VROCSTANMOD2337 (Black) and Intel VROCISSDMOD 2143 (Green) on-hand;

"...ISSD" = Intel SSD and Gen 4 card currently installed in P520; does not recognize Corsair 1T E100 M.2... According to Intel, Samsung 990PRO will be recognized...
will soon be testing 990 EVO Plus.

Will tune back in.

Update:
While Intel indicates that Samsung 990 PRO is compatible with VROCISSDMOD 2143 (Green)
I assumed that the 990EVOPLUS would also be compatible... WRONG!! (as they say about "assume"...)

I tried with both ASUS V2 and ASUS Gen 4 cards... no dice 🙁
While the VROCISSDMOD ("Intel only") may "only" be 45 bones... vs. 200 for the "VROCSTANMOD"
good luck wile spending a small fortune to find compatible M.2 drives

The STANMOD worked (RAID 10) with 4@ 2T EVO 870 SATA SSDs.
...As for the speed freaks, forget it... with P520 and P720, the best PCIe "link" will be x4
fwiw

PCIe slots have to be put into a bifurcation mode to properly identify multiple devices connected using one of the Asus Hyper cards. In an off the shelf setup there will be BIOS settings to split x16 lanes into x4/x4/x4/x4, but I'm not sure how that would be handled on one of these systems. I'm unsure if this is related to your issues as it's not super clear, but perhaps it can help.

I am very well aware of Intel VROC/ Lenovo BIOS set-up; The question remains:
"what is the difference between:
ASUS Hyper M.2 x16 Gen 4 Card,(mfg Date: 09 2024)
and ASUS Hyper M.2 x16 Card V 2 ? (cannot find date code)"...
Aside from physical layout of M.2 drives;
The V 2 has M.2 drives tightly shoe-horned together... Most likely heat problems
The Gen 4 is roughly 7cm longer... with vastly improved air flow.
Also, vs. Gen 5 card?
(p.s. how to add photos/images from PC to posts?)

V2 is a PCIe 3.0 model, but it does specifically mention VROC. To my knowledge there's nothing in those cards which should have any actual impact on VROC. Looks like the only difference between the V1 and V2 was the direction of the M.2 slots.

The different PCIe specifications are the maximum generation supported by the card.

Ah, so, "Gen 4" supports up to PCIe 4.0... "Gen 5", likewise PCIe 5.0...
Being able to post images would explain my concerns regarding potential heat problems with V 2 Card...
Will most likely unload it and pick up another Gen 4.
Also, regardless of which Card, what one may assume a logical progression from 990PRO to 990EVO PLUS, was also a fatal flaw; VROCISSDMOD purportedly accepts 990PRO... 990EVO PLUS was a failure.
(4@ 2T 990PROs are in the pipeline)
"Decoding" the Intel VROCISSDMOD compatibility list has been... "anti-productive".

Thanks for your help.

Yeah everything about VROC had always been really messy (I haven't used it on anything newer than Skylake era) because it was originally not just additional revenue for the paid unlock but locked to Intel SSDs as well.

Gen 4 versions offer higher PCIe 4.0 speeds compared to the V2 versions, which use PCIe 3.0 and deliver better performance with new SSDs like Samsung's 990 Pro SSDs. When you install your Lenovo P520/P720 RAID 10 configuration using Gen 4 cards can provide increased performance and future compatibility, make sure your system is compatible with PCIe 4.0 to achieve the best performance.
