I was wondering if anyone has upgraded the SSD in the Yoga 920 to something other than a PM961. Are any SSDs compatible? The Hardware Maintence Manual mentions the Samsung PM961 in a variety of capacities (256 GB, 512 GB, 1 TB). But I am interested in upgrading to something like a Samsung 960/970 EVO/PRO.

Read this post for information (this is not your machine type).
M.2 SSD / PCIe 3.0 x 4

I know that I have an M.2 PCIe slot. I was interested if there was any sort of white list/black list on which SSDs I can put into it since from expeirence I found that Lenovo likes to do that with wireless NICs.

Welcome to the forum.
WiFi and WWAN cards must comply with government regulations that vary from country to country. For example in the US the FCC regulates specifications including the frequencies, transmitter powers, level of spurious signals, etc. that are allowed for WiFi and cell data. Lenovo uses whitelists to ensure that only cards they've tested to ensure FCC compliance are used in their systems.
None of this applies to SSDs so there's no need for whitelists. The only issue is whether a particular SSD model has electrical and physical specifications that are compatible with the system in which it's used.

Be aware that changing the SSD in the Yoga 920 is not as easy as most laptops! You have to remove the motherboard as the PCIE slot is underneath. Fortunately for me, my Yoga 920 had a decent Samsung SSD when I purchased it end of last year. I recently checked it on Crystalmark and it gets 3000/1500 read/write performance which is pretty decent even now. And it’s 512 GB with plenty of space left so I nixed plans to eventually put in a 1 TB 970 EVO PRO down the line due to the hassle.

Yes, I know how to change the SSD via disassembling the laptop and removing the battary and mainboard to gain access to the M.2 slot, there are instructions on the Hardware Maintenence Manual. Thanks!

It's been said that you can't tell any seat-of-the-pants difference when it comes to SSD speed, particularly with NVME PCIE slot RAM. I have two desktops and two laptops, all purchased within the last 6 months or so, and I can confirm this (I even owned a 3rd laptop briefly for two months, so I can add to that mix). Opting for the current King-of-the-Hill Samsung 970 EVO Pro is mainly for bragging rights: 3600/2500 R/W advertised speeds I believe.
There is a significant decrease in boot times between a 2.5" SATA III drive and full size 3.5" SATA drive (550/520 R/W versus 150/150 R/W). But not a huge decrease in boot time between a 2.5" SATA III and a PCIE SSD. My Dell XPS 13 has a SATA III SSD with 550/550 R/W speed and it boots as fast as the Yoga 920 with 3000/1500 R/W speeds. Furthermore, I had an HP Omen laptop with a relatively 'slow' SSD running at 1150/1150 R/W speed and it was just as snappy as the Yoga 920. Owners of the 970 EVO Pro also said yeah, the R/W speeds are thru the roof, but they couldn't really tell any seat-of-the-pants difference compared to their old SSD running maybe 2500/1350.
So what I did on my Dell XPS is get rid of the 'slow' 128 GB SATA III drive it came with and bought the cheapest 1 TB PCIE drive I could find, an Intel which I got for $270 on promo from Newegg. Yes, that is a 1 TB NVME PCIE drive! Only rated at 3200/1600 R/W speeds but it will be plenty fast on that machine, plus the SSD is a breeze to swap out. I mainly use that rig to play YouTube videos on airplane flights. I currently have around 600 GB of videos which I was storing on a 2 TB external HDD, but I can easily copy all that to the 1 TB drive in the laptop now, and no need to lug the external HDD with me on travel trips .
