Not All First Generation PCIe 5.0 SSDs Will Offer the Same Performance

[TheLostSwede]

The first batch of PCIe 5.0 SSDs are all likely to be based on Phison's PS5026-E26 controller, which offers eight NAND channels, capable of supporting NAND speeds of up to 2400 MT/s. Phison's own figures for the controller are 13 GB/s writes and 12 GB/s reads, with up to 1.5 million random read IOPS and 2 million random write IOPS. However, as we've already seen from various SSD brands, many PCIe 5.0 SSDs won't exceed 10 GB/s when it comes to the sequential read/write speeds. This is because the current NAND flash simply isn't fast enough to saturate the PCIe 5.0 bus, which is capable of 15.75 GB/s. That said, Micron's 232-layer 3D NAND should be able to boost the performance up to 12.4 GB/s based on the numbers Gigabyte announced for their Aorus Gen 10000 SSD.

Based on an article over at Tom's Hardware, we shouldn't expect too many drives that exceed 10 GB/s sequential writes at launch, due to most drives using 176-layer 3D NAND flash, that is limited to 1600 MT/s. As such, it might be wise to hold off on buying the first generation of PCIe 5.0 drives and wait for better availability of 232-layer 3D NAND, as beyond Micron, SK Hynix is expected to have a 238-layer 3D NAND flash in the market sometime in the first half of 2023. If you're not really eager to have the fastest SSD out there for pure bragging rights, it would seem that mid 2023 might be the right time to get a PCIe 5.0 SSD.

im more interested what kind of cooling components attachments provided by motherboard manufacturers
to combat the massive heat output by the drives at max speed... pci 3.0 drives already get pretty hot and needs an aluminium heatsink on.

No 15GB\sec - no buy. I can't stand those turtle like 10-12GB\sec drives.

There are plenty of third party options otherwise, but yes, we're getting to a point where it's starting to get hard to cool the controllers.
I ended up getting one of these for my KC3000 SSD, as it was throttling when used with the motherboard heatsinks.

Can't wait until Noctua DH15's are needed to cool them NVME drives.

We can have one on our CPU, one on our GPU, one on each NVME, and suddenly we have six DH15's in our PC's. "All Noctua" suddenly has a whole new meaning.

I wouldnt be surprised if someone comes out with a drive comes out early 2023, earlier than suggested. There havent really been any leaks on that, that just means drive makers are better constrained. This is a good thing for 4.0 drive sales, so who's to say this delays were not planned?

To which I say, Bugger That!!!

PCI-E 4.0 SSDs offer plenty of performance. There are still people using mechanical hard drives LOL.

Well, I see no reason to store terabytes of music, movies and photographs on an SSD, unless I'm editing in Premiere. In fact, I'm quite curious about HAMR/MAMR hard drives and really want a couple of 20tb ones once they hit the consumer markets.

Right, but today I found out with horror my bf’s PC was not only using an HDD as the boot drive but a 5400RPM WD Green

Needless to say that has been resolved with a SATA Samsung 850 EVO 250GB he got for free.

But now the question is would the PC actually be faster with a 15GB/s PCI-E 5.0 NVMe drive? Well, sure, but it’s a point of diminishing returns.

For everyday using and gaming none of these things matter. For enterprise or workstation use, sure, these new drives will matter. But for the average person just trying to play GTA V or Cyberpunk 2077 or whatever games the 4.0 vs 5.0 SSD is not going to matter. And they’re better off with the cheaper drive and putting a few extra bucks towards a different component.

Not at all!

Now that AMD's 3rd Gen Ryzen processors are officially here, accompanied by the new x570 motherboard

And this was before all the throttling become common knowledge. There was an article regarding Gigabyte getting 5000Mb's in "low temperatures"

Begun it has, the quest for MOAR SUPEEED...

not that it ever really went away, but in recent years it seems that many folks just can't get enough

I'm still recommending Gen 3 drives often since, for most people, the only tangible difference between them and Gen 4 drives is with large file transfers. Gen 5 looks to be continuing this trend. The performance bottlenecks aren't with the drives themselves anymore.

 

[Panther_Seraphin]

RAID 0 two Gen 3s and where is your bottleneck?

Even just a single Gen 5 now......

 

[Wirko]

It's possible that bifurcation becomes more common in the future, and that's when SSDs using one or two PCIe lanes are going to demonstrate their usefulness.

Possibly but the problem is that we are struggling to keep up with everything else. Think of like network adapters etc.

Looks like as good a time as any to wait. Any decent PCIE 4.0 drive will be sufficient for DirectStorage games in the next year or two until we get 5.0 drives that can saturate, also some controllers that might run a bit cooler.

I can already hear all of the people complain, who are not impressed with their upgrades, outside of synthetic benchmarks.

 

[Palladium]

Yaaaaaawn

I can already hear all of the people complain, who are not impressed with their upgrades, outside of synthetic benchmarks which they already should have fully expect.

Fixed.

Raid driver overhead / CPU bottleneck.
Also mainstream platforms are always short on lanes.

 

[1d10t]

Bring that substantial upgrade like 5GB/s in 4K Random.

 

[ixi]

Great to see new new top, but at the same time it will be overpriced. Is it really requied? No it isnt. Gen3 and gen4 will do just fine.

 

[Chrispy_]

We don't need PCIe 5.0 yet.
Nothing is ready for it, and you still need to find some pretty specific scenarios where the limitations of even PCIe 3.0 storage are meaningful.

Yes, the differences are measurable - but is saving 0.8 seconds on a 45 second operation really going to make a difference to anyone in the real world?

It is relevant to video editors that work with the very high end stuff- RAW data of 6K-8K video.
Those files weight by the hundreds of GB to TB per file (it`s about 100-120 GB per minute).
Anyone else may pass.
