For normal desktop users the persistent storage will allow for lightning-fast startup of the OS once Microsoft is finished with their tweaks. We'll see what else they have planned. If you do not see the importance of persistent memory I don't know what to tell you. Storage and memory is still a major bottleneck for every datacenter and workstation and this addresses it.
The database servers (or for that matter, pretty much any server) do not need to restart quickly, as every enterprise business in the history of forever has one of the following;
- Change control / scheduled downtime
- Redundant servers
- Resource pooling
Additionally, most databases are not hosted on Windows, and lol, you think servers don't do a full RAM training every single boot up and take 10-20 minutes to POST. 3TB of Optane will make that take a literal hour. Welcome to actual
I don't know if you realize this or not, but most PCs with NVMe already start in under 5 seconds... Also;
- AMD provides 256GB/s or more of PCI-e bandwidth and a theoretical cap of about 200GB/s of RAM bandwidth.
- Six channels of DDR4-2666 provides about 128GB/s.
- AMD provides support for 4TB of RAM per CPU.
- Optane DIMMs support 3TB per CPU.
Optane DIMMs are DoA. If you need that much data that quick, then Optane DIMMS will not help you.

on that note, the biggest benefit of using RAMDisks is the superior 4K-IO performance of RAM, not to mention drastically reduce wear on SSDs.
RAM Disks are software cache, and not worth the pain.

Just rolled out a cheaper, faster 910p SSD with more capacity option for us and we will be glad. 256GB will be sweet spot as a price / capacity Boot drive.
Yup. Optane good, Optane DIMMs useless.

They bottleneck whatever you are doing almost every time you use them.

Want to view an image? Wait for it to load into RAM first.
I don't think you know what this point was addressing. It is not just a faster hard drive. A change to the OS so it doesn't need to load a bunch of files off of storage before running doesn't seem useful? Persistent memory takes functionality like Windows' "Hibernate" to a entirely different place. Just turn it off and on, with no boot at all. Your applications are still open and you didn't need to load gigabytes off the disk first, or save them when turning it off. Whatever Microsoft is working on now probably won't get to the full potential of persistent memory but you are writing it off as the same as moving from a SATA to NVMe SSD?!?
Wow, you really think that having your data already in RAM is useless? Do you know what Von Neumann architecture is referring to?
You also seem to think throughput is the only important metric for storage but at this point random access is much more important for normal use. A NAND based SSD is never going to go above ~60 MB/s for true random access (this is why NVMe is not much better than SATA in many real world use cases...). Manufacturers are figuring out cheaper and slower NAND, not faster. 3D XPoint is persistent solid state memory that can actually do decent random access too. "Useless crap"
Why? Slower is better? NAND sucks in general, 3D Xpoint is way better. I don't see how PCIe 4.0 is going to help NAND get better random access, which is where it is slow now. Moving from 2GB/s to 4GB/s sequencial is not going to change the feel of a computer for anyone, it won't change load times for games or programs and it won't it help it boot faster. What is actually improved at the consumer level by moving to PCIe 4.0 NAND based SSDs? Moving from 60 MB/s to 500 MB/s for random 4K would have a much more noticeable impact.
Optane DIMMS are not RAM, and this change will not affect that. They are SSDs on a RAM bus running at 2666. 21.4GB/s per SSD is great compared to one M.2 or U.2 SSD at 4GB/s, but reality is that, as you note, Randoms are what matter. Optane DIMMS will not significantly out perform traditional NVMe Optane in Randoms, and they will NOT provide RAM-like response times.
Given Intel's history of not tagging data and their recent security issues with Cache and RAM... I'd keep it in storage thanks.
4GB/s to 8GB/s. PCI-e 3.0 is 1GB/s/lane, 4.0 is 2GB/s/lane.
Agreed, which is why I run Optane as my OS drive. But... this thread is specifically about the DIMM version, and I get the speeds you are speaking of out of a normal NVMe Optane drive.
Why would I waste RAM slots?
