I wish companies made consumer PCIe x8 SSDs. It would be good since many motherboards can split the PCIe lanes x8/x8 and SLI is falling out of favor anyways.
I bet 90% of motherboard buyers would prefer 2 x16 slots vs any other configuration so they can run 1 GPU and 1 very fast SSD. I really don't understand why the market hasn't moved in this direction.
performance would not be very noticeable. and even in the few cases it would be, it would require more expensive cpus and mobos thus mitigating the attractiveness to very few consumers. and fewer consumers means even higher prices. we will get higher throughput but its much more likely with pci 4.0/5.0 than 2 16x
Because the PCIe lane count is dictated by the processor and Intel has been notoriously light on the number of PCIe lanes for their mainstream products. So is AMD for that matter (Ryzen). Threadripper though has a large number of PCIe lanes, along with EPYC. XEON is also more then standard desktop procs. From reading around it looks like cost is the main reason for the limited PCIe lanes.
And the reason for limited PCIe lanes is that the number of them are controlled by socket size, and socket size is constrained by cost. (And once you get up to truly enormous ones like LGA3647 or SP3 by the fact that they take up so much physical space that smaller form factors like ITX become nearly impossible and highly wasteful because you're unable to use most of the CPUs IO.)
It would be great to be able to buy such drive for high-end workstation at home, even if they're only for enterprise. Such write endurance and power loss protection cap... Is there any pricing revealed anywhere?

That. Capacitor.Billy Tallis - Wednesday, March 13, 2019 - link
Yes, sometimes "power loss protection capacitor" doesn't need to be plural. 1800µF 35V Nichicon, BTW, since my photos didn't catch the label.willis936 - Wednesday, March 13, 2019 - link
That’s 3.78W for one minute if they’re running at the maximum voltage rating (which they shouldn’t and probably don’t), if anyone’s curious.DominionSeraph - Wednesday, March 13, 2019 - link
It's cute, isn't it?https://www.amazon.com/BOSS-Audio-CPBK2-2-Capacito...

Because SSD's have a hard time saturating 4x PCIe slots, 16x would just take up space for no real purpose.Midwayman - Wednesday, March 13, 2019 - link
Maybe, but it sucks that your GPU gets moved to 8x. 16/4 would be an easier split to live with.bananaforscale - Thursday, March 14, 2019 - link
Not really, GPUs are typically bottlenecked by local memory (VRAM), not PCIe.Opencg - Wednesday, March 13, 2019 - link
