pushing the capabilities of NVMe Gen 3 to meet the demands of a rapidly growing market

What use is to try to push the capabilities of Gen 3 when you can just go to Gen 4 to get more speed with less pushing? Intel plebs will still be able to use it with Gen 3 speed if needed.

Meet a price point? And not opt in for choosing one of the 2-3 expensive gen4 controllers?

So, pushing the capabilities of Gen 3 means picking the cheapest path? Right, I failed to consider that. The choice of words might not have been the best in the product announcement.

Define speed 😉 I haven't seen any pci-e 4.0 ssd that has faster 4k random read @QD=1 than Adata sx8200pro pci-e 3.0 and HP ex950 pci-e 3.0. Not many need or can use the high sequential read and write speed of pci-e 4.0 ssd's. Very high seq read/write is more a "gimmick", than a actual useful for most people. I have 2x 8200pro in raid-0, but it's hard to find a scenario that use 7000MB/s read/write speed 🙂 I'm using raid-0 to get one bigger volume. Moving big! files from one fast medium to another is one scenario that utilize high sequential speeds. The problem is that you need fast medium in both ends 😛 My 10Gbit lan is too slow to my main server, so even one pci-e 3.0 ssd is overkill 😛 OS station with Optane 900p is almost faster in all scenarios, than 2x8200pro in raid-0, even the seq read and write is way slower. 4k Random read @QD =1 is ~310MB/s on 900p VS ~75MB/s on 8200pro.

Is there some technical limitation to why Gen 4 can't have the random read speeds of Gen 3? I reckon it's just due to the controller. If nobody bothers to make a proper controller, then that's it. Although I wouldn't be awfully surprised if the first gen PCI 4.0 in Ryzen 3000 wasn't quite up to it either. After all, Intel failed to make their PCIe 4.0 to work at all, so it's not easy. However, it ought to be possible to make a better controller if someone invested money in it. However, no matter how much you push, Gen 3 sequential can't pass Gen 4's.

2To PCIe 3.0 cost the price of PCIe 4.0 with 1To... Until the demand will rise it is more money friendly to buy a PCIe 3.0 (like the M2 SATA when the M2 PCIe appear in shop).
