The upcoming Samsung 990 PRO flagship consumer SSD has recently been listed as PCIe 5.0 compliant by PCI-SIG with the entry also confirming the drive's name and M.2 interface. The upgrade to PCIe 5.0 from 4.0 doubles the available bandwidth for the card with Samsung's existing enterprise PCIe 5.0 drives reaching speeds of 13,000 MB/s significantly above the 7000 MB/s of the best PCIe 4.0 drives. The latest Intel Alder Lake systems can support PCIe 5.0 drives on select motherboards with AMD support set to arrive with the launch of Ryzen 7000 and X670/B650 motherboards. Samsung is expected to release at least 1 TB and 2 TB variants of the drive however other details such as the exact length of the card and the controller used are currently unknown.

They need higher density NAND chips for this to happen, unless you want to pay double for a drive that's basically two NVME's in RAID

Not necessarily. They could make double sided M.2 version that has NAND chips on both sides. So 4TB is doable with existing layer counts.
8TB should be doable with 230+ layers that other NAND makers have revealed recently. So i assume Samsung also has one in the works but have yet to announce it. The problem is that those high layer count packages will not enter mass production until the end of this year or beginning 2023 most likely.

And fit that on an NVME drive?
With existing controllers?

Sadly i dont think we're gunna see size increases for a year or two, outside of QLC drives

Yes. Current drives are mostly single sided so it's possible tho thermals would be worse. The controller is not an issue as Gen5 requires a new controller design anyway. Besides 8TB is small considering that enterprise drives support over 30TB. Makes no sense for consumer drives to be limited to only 2TB.

And if Samsung will not produce 4TB and 8TB Gen5 options then im sure Phison and/or Silicon Motion will.

Let's hope it's not another TLC product just like 980 Pro, but probably will be.

Who needs speeds of 13,000 MB/s realistically? I can't notice the difference between my WD SN570 (PCIE3 3300MB/1200MB/s) and Samsung 980PRO (PCIE4 7000MB/5000MB/s). I installed OS on both SSDs and see no real world difference in boot times, apps installation times, loading times or Premiere... PCIE5 SSD is a waste of $$$ for 99,99% of desktop users imho.

Wasn't this what their competitors announced recently? I wouldn't expect Samsung to be far behind and this might be the first product using it.

No consumer, at least not today.
However, the new controllers will hopefully improve the IOPS and RND performance, together with more advanced NAND flash, which would be far more interesting at this point.

Of course it will be TLC, no-one makes dense or fast enough MLC for a product like this. 3D stacked TLC is the future for NAND, for now.

More marketing noise
  • It needs to have better 4K QD1 read and wright speeds than my 960pro (new its was 65MB/s and 260MB/s)
  • Its needs to have ewnough SLC cache that when Im copying/moving multi gigabyte files the sequentional perf dosen't fall off a a cliff after only 1GB - AKA Samsung 980pro.

I would love speeds of 20,000+ MB/s for when we get DirectStorage game asset streaming. I hate to see "hitching" and micro stutters in my games. If a new NVME had 20,000MB/s read bandwidth that is only 20MB per millisecond, and games need to stream those assets in within 1-2ms to not hold up frame times. Considering we quibble over 10 nanoseconds of memory latency to get a couple extra min FPS and people want 120+ fps/hz, I think keeping bandwidth as high as possible so that asset streaming can be down within a millisecond would be something we should strive for.

13K MB/s Sequential reading, which actually doesn't matter at all in real life use, but still 50MB/s on 4K Reads :laugh: :laugh: :laugh: , for double the price, most likely.

Query:
Will Gen5 devices 'max out' a Gen4 bus, or will we see some kind of overhead?

Theres no guarantees double sided NVME would fit in devices, so I don't see that happening.
Controllers only have so many channels - 8 16 and 32

So 32 channels by the current 512Gb (64GB) modules = ... 2TB.

You can't get bigger without new NAND tech coming out.

There exists 8TB TLC with 112 layers today based on Phison E18 Gen4 controller. So clearly 4TB and 8TB are doable even today. In the future with higher layer count chips these can be made single sided, run cooler and consume less power. But it's doable. That's my point.

Also current M.2 drives use much bigger chips than 64GB. More like 512GB-1TB.
