- starfallg 6y agoThe M.2 interface only supports up to four lanes of PCIe.
- 867-5309 6y agothanks for pointing this out - I was unaware
- ksec 6y agoAnd we already have roadmap for PCIe 5.0 SSD. So sometime in 2022/2023 we get DDR5, PCIe 5.0 and may be an SSD that reads up to 15GB/s. ( And still no roadmap of Affordable 10Gbps Ethernet, even 5Gbps would have been acceptable. But looks like we will only get 2.5Gbps as replacement. )
- Tuna-Fish 6y ago10Gbps will become affordable in 2023, when the last patents covering it expire. 10Gbps right now is not expensive because it's expensive to implement, it's expensive because the royalties demanded by the patent holders are absurd. They are so bad they are probably counterproductive -- if they asked for less per port, it could have maybe ended up as the default standard on every device already, resulting in more royalties overall. In any case, the last relevant patent expires iirc summer of 2023, very soon after that there will be a lot of fast, cheap NICs, and soon after that, it will just be embedded into everything.
- ksec 6y agoOh wow thank you. This is the first time I've heard about it. Edit: This? 2023-07-18 Adjusted expiration https://patents.google.com/patent/US7164692B2/en https://patents.google.com/patent/US7164692B2/en
- Tuna-Fish 6y agoYes, I believe that's the last one. IIRC there's another important one that expires like two months before.
