When will the OEMs implement U.2 in Mainstream class motherboards ? I think never. Because many people are fine with using garbage M.2 SSDs over SATA ports and nobody even know SAS connectors which build upon SATA and Enterprise SAS has PCIe4.0 class connectors.
Also people just simply want spec sheets for M.2, the PCIe bandwidth is all the focus. Nobody even sees how the TBW is / Endurance. Stability of the SSD in NAS or high workloads 24.7 and other aspects.
I mentioned already a few times that PCIe3.0 SSDs had very good TBW ratings and PCIe4.0 dropped the ball very hard. Now we barely have anything in PCIe5.0 M.2 SSDs.
Sabrent had 6400TBW for 4TB, now its less than 3000TBW for most. SN700 PCIe 3.0 NAS SSD has 5100TBW, Seagate did 530 with 5000+ TBW but now they do not, and most importantly most of these SSDs are failing if you see the ratings in Amazon, or in STH server forums.
Now Samsung is so proud of their QLC, and consumer QLC will be complete pos junk. Esp given how poor their Firmware and QC were for 980/990 pro. WD Black as well, absolute joke. 8TB 850X has 4000TBW lol, even a Samsung 860 Pro MLC SSD from bygone era had 4800TBW in SATA 6Gbps for a 4TB drive.
Mechanical drives get bad rep, but those are the only ones which are reliability running without BS issues and they are also having high capacity. I can get a 20TB OptiNAND WD Red Pro / Gold for under $400 during discounts, that is a top drive btw for those who are unaware in HDD technology. There are more expensive ones, and still they all are cheaper than any 8TB M.2 SSD.
On top all these companies esp WD and Samsung, advertise "Gaming" which is even more foolish, esp making people fools. There's absolutely no improvement in game performance when using SATA vs PCIe SSDs. Only advantage is seen in loading that too modern garbage optimization in games shows. Otherwise no perceived advantage. Direct Storage does not do anything either.
Too bad Storage is nowadays seen as last factor since most consumers are only interested in spec sheets, lack of knowledge, many dont even store Movies and Games in offline format.
I will wait for a good HEDT option or just buy a used X299 or older Xeon and a bunch of SAS Expander / HW RAID cards for a homeserver.
I agree about QLC garbage, i afraid recently to touch even TLC drives actually, but have question about U2. Why exactly mainstream mobos need U2? All server motherboards have it, isn't it? I have U2 on motherboard but still have not found any advantage of it over M2 -to- PCIe5.0 adapters.I can place there 4 NVMe drives + one on its own M2 connector and if use 4x bifurcation then probably the whole amount of drives could reach 4*4+1 = 17, all with the whopping up to 12-15 GB/s speed

"Samsung claims a 1.7x performance improvement and a 1.7x power efficiency improvement over the previous generation"So basically 1.7x performance at the same power draw to result in both of those marketing metrics.
