Bulk of PC's sold today, even low-end netbooks use SSD's.
Xbox Series X is also using an SSD.

Most devices today, including phones and tablets... You guessed it. Use an SSD.

What's your source?

First we can gather the marketshare of the most popular vendors... Let's use wikipedia.
https://en.wikipedia.org/wiki/Market_share_of_personal_computer_vendors

So that means Lenovo, HP, Dell, Apple, Acer and Asus which accounts for 81.3% of the PC OEM market.

Then we trod over to each individual manufacturers website... Which is:

www.lenovo.com
https://store.hp.com
or www.dell.com

From there I will use something like Dell.com as it's got a decent sort function by hardware components.
And they only have 3x notebooks with a mechanical hard drive, the Dell Inspiron 14 5000 and 15 5000 models.

But then they have 23x models with a 128GB, 256Gb or 512GB SSD aka the Dell Inspiron 14 5000, 15 5000, XPS 13, Inspiron 15 7000, XPS 15, various 2 in 1's and so forth.

Even the shitty budget netbooks like the Dell Inspiron 15 3000 with an AMD A6 9220 has a 128GB SSD.

Are there PC's with mechanical drives being sold? Shit yes. But that are certainly the exception and not the norm.

Even Anandtech recognizes for end-user systems that SSD's are the main seller, not mechanical drives.
Mechanical drives still hold relevancy in cold storage/workstation/server markets where their capacity and long-term reliability without being powered on is highly valued.

And I quote: "Data storage requirements have kept increasing over the last several years. While SSDs have taken over the role of the primary drive in most computing systems, hard drives continue to be the storage media of choice in areas dealing with large amount of relatively cold data."

He is talking in hypotheticals, he says it himself.

I am not sure of the benchmarks, but from what I understood from the Linus video, even with 4 Gen 4 NVMe M.2 in a raid plugged into the PCIe port, due to the bottlenecks in how the OS (even Linux) handles the I/O requets, it looks like the PS5 custom SSD @5.5GBps, with the I/O magic using dedicated chips, it seems to beat even PCs today, and that's why it's making noise even with guys like Tim Sweeny from Epic.

Here are the custom chips the PS5 seem to be using:

  • Dedicated DMA Controller

  • Dedicated Decompression Chip

  • 2 I/O Co-processors

  • On chip SRAM

  • Coherency chip ( which link to the GPU Scrubbers in the diagram as Cerny informed )

In terms of brute numbers, even if the Aorus offers 15GBps, in the end it seems like the architecture of PCs is limited for this use case, and the change in architecture in consoles may feed back into the design of gaming PCs in the future.

Here is the linus thread which I found interesting, discussing this subtle point:

https://gamrconnect.vgchartz.com/thread/242553/linusive-disappointed-and-embarrassed-myself-re-ps5-ssd/1/

I don't actually disagree. But if you still want the absolute best sheer sequential throughput, you can achieve that on PC, but expect to pay out of the nose for it.

Obviously there is allot that goes on "behind the scenes" when it comes to storage and Sony has invested a shit ton into working on that... If anything that will mean the rest of the industry will take note and start resolving those issues going forth, it's a good thing for the entire industry.
