You could be right. We can hope for M10 being Carson Beach? Totally speculative though. The pricing list on retailers have a significant premium for M10 so I hope we get more than few power saving features.With Carson Beach being a new controller (and available in BGA SSD according to that old roadmap) maybe that will be the controller with the low power to match the best NAND based NVMe SSDs?
The Brighton Beach products have 2x the maximum write performance. That means it may have 4 channels. That means it may need 8 channels to make it 1300MB/s. And with x4 interface the writes can go close to 2GB/s.P.S. My guess is that Carson Beach will have four channels (slotting in between the two channel of Stony Beach/Brighton Beach the and seven channels of Mansion Beach). If true then maybe 120GB Carson Beach will have 1200 MB/s Sequential write.
I haven't got an answer why the 16GB Stony Beach model has half the write performance of single channel in a 900P device.
No point. Host Memory Buffer is a cost-saving feature. It still needs to go through the PCIe interface and thus has significantly higher latency than DRAM on a DRAM bus. There will be a negligible gain which will be unnoticeable compared to NVMe 3D XPoint.One more thing, I noticed Brighton Beach is NVMe 1.1.....but I wonder if Carson Beach will have NVMe 1.2 and support for Host Memory Buffer? If so, will we see any improvement using System RAM? A tiny improvement?
