Random read and write is the most important thing for real life disk usage and yet it seems pcie4.0 drives at moment does not offer any benefit x pcie3.0 and yet they will cost a lot lot more.
No, we are way behind any "usable" max random RW. While we're covered well by the sequential speeds that we have now (1-2GBps), we are left in the dark when it comes to random (where we barely get 50MBps). I'm talking low QD, stuff that matters.
While 10 times faster sequential RW won't make any difference in real life, 10 times faster random RW would make a hell of a difference. Get me a drive that gets not 3 but 300GBps seq, my laptop won't be able to exploit it, but get me a drive that does 100 and not 50MBps 4k QD1 and all apps on my laptop will run way faster.
Meh. More random would be nice but not that long ago ultra expensive SAS enterprise drives were doing 200 IOPs. Even a storage server array with 48 drives might crack a a couple thousand IOPs. These SSD are doing 600K. Sure 6M would be even nicer but we have random performance that was simply unheard of at any cost in a $200 SSD these days.
We has always had this assumption where Super Fast Random RW is far more important, and yet all the test with Optane shown in Real Life Workload benchmark this isn't the case. Seq RW is still extremely important in nearly all cases, and especially the so called "lightweight" benchmarks on Anandtech.
So no, your 10 times faster Random RW wont makes "hell" a lot of difference.
Everything new costs more but long term PCIe 4 shouldn't be more expensive than PCIe 3. In fact in a lot of cases it could be cheaper. Entry level NVMe SSD could hit ~3.5 GB/s just using a cheaper 2 lane interface.
Seeing that they just replaced the PHY with PCIe 4.0 without any change to the actual controller, Then it's expected. They did that to accelerate the release of the PCIe 4.0 ssds, which will help with bandwidth. Native and actual PCIe 4.0 will surely have better optimization and utilization of PCIe 4.0 speed and features.
This was rumored to be the SSD controller Sony is starting with before customization, it would be funny because "PS5" is sitting right there in the name, even if it's for unrelated reasons.
It has a dragon on the box so it must be fast. The only thing faster than a dragon is a brand-deprived 3D render of a sports car and an insufficiently dressed woman brandishing combat implements. Specs, at this point, are unimportant since the image tells us its performance tier.
This device is very good and of high quality. I don't use it for a long time, but it's very convenient for me. Now, with my education and work, this page https://supremestudy.com/ helps me, because finding a quality essay writing service is as difficult as choosing a laptop or drive. I think it's very cool and saves time. Play games on a new laptop.

Once you clear a usable maximum random read/write I'm not sure I'd call it the "most important" thing for most people.cgeorgescu - Tuesday, July 2, 2019 - link

Companies will want to milk as many people from their $$$/£££ before truly offering something much faster.MrSpadge - Tuesday, July 2, 2019 - link
That's not the fault of the interface if thise performance is the limit of what the controller can do.Xajel - Thursday, July 4, 2019 - link

Lol, yeah that is a remarkable coincidence to say the least and quite hilarious to boot, pun intended.PeachNCream - Tuesday, July 2, 2019 - link

You are correct. But place that brand-deprived 3D render of a sports car and show it coming out of a monitor, to make it super ultra fast.magreen - Tuesday, July 2, 2019 - link
Don't forget the letters G, T, X, and O in random number and order for ludicrous speed.rems - Wednesday, July 3, 2019 - link
I thought DWPD was TBW/warranty? That gives 2DWPD for the CFD PG3VNF 2 TB, half for the 1TB and 1/4 for the 500GB which makes sense, no?TheUnhandledException - Wednesday, July 3, 2019 - link
All of the drives are ~1 DWPD.850 TB / (5 * 365 * 0.5) = 1 DWPD (well technically 0.931)
1800 TB / (5 * 365 * 1) = 1 DWPD (well technically 0.986)
3600 TB / (5 * 365 * 2) = 1 DWPD (well technically 0.986)

So, the real question is when can we expect a true PCIe 4.0 controller (which is what we thought we we getting with this launch).Henri_89 - Tuesday, February 23, 2021 - link
