Heads up, they will need a 25mm socket as opposed to the 22mm we are used to. Apparently this was always in the PCIe 5 specs but no-one thought to tell the us (it has always been an M2 physical standard). Its been spotted in specs for the new Gigabyte X670 mobos by the Tech mags who then asked questions as to why.
The X670’s do have 25110 slots so we could see 110mm drives becoming common in the future too. These are very unusual ATM and not aimed at consumer kit, most mobos can only deal with 80mm and 2280 drives are the most common now.
It seems heat will be the issue, so more space will be needed for cooling solutions. 3mm doesn’t sound much, but it is a 15% increase in surface area compared to a 2280 drive and a whopping 56% if you go to 25110.
This isn’t going to be a problem if you are buying a new PCIe 5 system, and a 2280 drive will still work, OK so you can bring an old drive forward. However, what you can’t do is what I have done in the past, buy a higher spec NVMe drive now with the intention of moving it to a new system later.
The 500GB Crucial P5 Plus I put in the Thinkbook was £60 well spent and is just the sort of drive that fits in that category. It’s not that much more than a PCIe 3 drive and outperforms more expensive PCIe 4 drives.

Yeah OK.
Obvs I’m no engineer. But for the end user like me. I doubt it will ever apply.
But yeah if its the requirement for pci-e 5 then thats fine.
I guess its the first real change since we saw hot swop sata introduced.
For me It will be great to see how applications are made to utilize this new tech and what new feature of use it will bring to the table.
June 5, 2022 at 7:39 pm #69586Being more than just a tad cynical, and a person who is used to marketing spiel, this Intel release is refreshing as reading between the lines the differences between PCIe3 4 and 5 are ‘not a lot’.
Cutting to the chase the differences between the three is bandwidth, but really only storage bandwidth may use this at present. In fact Intel say until better drivers are developed even that is a bit iffy.
“Currently, PCIe 4.0 SSDs are designed to have higher maximum read/write speeds than PCIe 3.0 SSDs, but their current real-world advantages in areas like loading times and large file transfer are small. Over time, however, new memory controllers will be released and both games and applications are expected to take greater advantage of modern SSDs.”
According to Intel the main value of using PCIe5 is future proofing for the day when drivers and hardware use the capability that it will provide:
“As mentioned above, each generation of PCIe doubles in throughput. But the real benefit of PCIe 5.0 is full backwards compatibility and future-proofing: you know that new hardware won’t be bottlenecked on your system.”
*At the time they wrote the article Intel did not really know what tangible benefits will come from PCIe5. They did however speculate:
“PCIe 4.0 and 5.0 devices. Though you might not spring for a PCIe 4.0 SSD or GPU during your initial build or purchase, it’s easy to see why support is useful down the road. Maybe ports of new console games start relying more heavily on streaming in assets, and a PCIe 4.0 SSD provides a tangibly smoother experience. Or the next generation of GPUs benefits from the doubled throughput of PCIe 4.0 and 5.0 slots. ”
I read this as saying don’t get too worried about it at the moment but do keep it in mind for your future PC unless you are into AI or Bitcoin mining in which case you may want it earlier.
*I do wish technical articles were date-stamped, as I have to assume that the thoughts are still current!
Digital Trends have a reasonably current report, but share the same conclusions adding only that it ‘might’ allow smaller desktops/consoles – not sure I understand why that should be the case but hey ho!
June 5, 2022 at 7:53 pm #69587Yeah. Bandwidth always seem to help. Esp with GPU’s
Introductions of new ram DDR:2,3,4,5. Less so.
For me the introduction of a new DDR is yawn time.
June 6, 2022 at 9:36 pm #69588Yep, it’s all subjective. I store a lot of (relatively) large files on a TrueNAS server and the extended load/ save times don’t really bother me. But Synology Drive combined with Windows Storage Sense gives you files on demand with automatic clean up and really is very good.
What makes the difference for me is boot times and responsiveness but TBH it’s a game of diminishing returns after read speeds of ~1500 MB/s. I haven’t had to deal with a PC booting from a HDD for ages, all the ones I’ve seen are because of drive failure. I think it would drive me nuts.
