Not really, its available now and less than NVMe drives. For context sake we know the OnePlus 7 Pro has 128GB vs 256GB has a price difference of about $30 bucks. It would be a fair assumption to think the 128GB drive is $30 and the 256GB is $60. By contrast a comparable nvme drive is going to run you more than twice that on Newegg. https://www.newegg.com/samsung-960-evo-250gb/p/N82E16820147593
I'm not saying this is definitely it, but it makes the most sense and they could even have a more custom variant with higher performance.
Thanks.
I can't seem to understand this guy's presentation. What exactly does he mean that UFS 3.0 isn't as fast?

NVME can seem to come down in price through lots of sales the past few months about $ 100 / TB:

I imagine bulk purchases by Sony and MS would be much cheaper.
How inferior is NVME x2 compared to UFS 3.0?
He is referencing sequential reads vs random reads. NVMe excels at random reads. UFS excels at sequential. Even at the lowest real world estimates for UFS 3.0 it out paces the highest theoretical performance for NVMe x2 at 1.6-1.8GBps in sequential reads but UFS suffers in random reads. Random reads really benefit exactly from what it sounds like. Unpredictable activity such as launching apps by the end user while sequential reads would be something like 4K video where the information is kept in blocks located close together on the storage media. Again, in a console you do not have a bunch of apps opening. The console has one primary function so it will be relatively easy to manage memory. Even in open world games there is only a finite amount you need to swap into memory at high speed and any load times that would occur would be so minimal that a developer could mask them easily even for something for fast travel. Basically it would enable load times in the single digits if even that for far cheaper and less cost all around and more wattage can be allocated to the GPU or RAM which is vitally important. You wouldn't want an SSD to suck up a significant amount of cost, power, or space at the expense of everything else just to get a second or two less of already low load times. That's what consoles are trade offs because there comes a power where solutions are "good enough" and balance out for the best for the consoles.
NVMe excels in both random and sequential

Sequential read reached ~3.1 GB/sbenchmarked (not theoretical) for Samsung PM961 nvme.
Highest theoretical performance is useless. Ryzen's results are slightly less than Intel's.
Sony has used laptop 2.5 inch HDDs in PS4s.
You keep posting high performance specs for a storage solution that is 2-3x (200-300% more) the price, 3x (300%) the power draw and heat, 5-6x (500-600%) the size and only yields a 25% increase in performance for what is needed. That's the point. It's like comparing a Ferrari to a Mustang. For the space and cost of an NVMe solution Sony could put multiple chips with their own bus and it would perform better in every metric including price. The NVMe controller alone pulls more power than the entire UFS 3.0 solution. Further performance of NVMe as a whole degrades as much as 25% as the solution warms up over the course of 30 mins due to its excessive power draw. After 30 mins, performance of most NVMes becomes erratic or degraded.
