And what am I missing vs top of the line CFE-B cards? Aren't these speeds roughly the same as years-old CFE-B cards?
Yep, that's exactly right. CFE-A 4.0 cards are the same speed as CFE-B 3.0 cards. The shift from PCIE 3.0 or 4.0 doubled the bandwidth. Type-A cards are still only one lane, where as Type-B cares are two lanes. If/when they moved to PCIE 5.0, they'll double the bandwidth again.

FWIW, and IMO interesting note, I'm also learning the CFexpress A-B adapter allows to use CFexpress Type A cards in both CFexpress Type B card readers and in some mirrorless CFexpress Type B cameras, but not all.
OTOH, As someone is sure to point out, CFe-Type B 4.0 can be less expensive and up to twice faster. But if you are already spending big for Type A cards, maybe a convenience to be considered if you own both type cameras.

many things are possible, yet not particularly advisable, in this world. who would spend this much money on high dollar cards and introduce an unnecessary level of jank to their equipment?! stay tuned to find out

I thought about the OWC card with 4 it’s like 319 for decent size maybe 420
Shooting speed I’m fine but download speed that’s money to me
The OWC cards are excellent price! And for sure up to doubling file transfer speeds can indeed be "money", for some high volume situations like your events.
I decided to go with the Exascend 1TB card for the specs: VPG400 and up to1650 MB/s sustained write speeds, something I will be testing next . But not everyone needs these higher specs.

Thinking of getting one for NY next month.
The nice thing about the OWC Type A 4.0 cards with the OWC reader is you can use OWC's Innergize™ custom-designed app.
"OWC's Innergize™ is a complete health, performance, and field firmware upgrade management tool that ensures OWC Atlas memory cards are always ready to boldly deliver the highest level of workflow performance and reliability." AKA a way to refresh, reformat and health check the cards. *Other companies like Prograde have a similar app service for their cards and readers.
The OWC cards come with an OWC A-B adapter which is needed to use with the OWC USB 4.0 card reader which is currently a Type B, 4.0 reader. Not sure if they plan to ever offer a Type A 4.0 card reader, but from my recent experience, the A-B adapter seems to work seamlessly ...so far.

So get there reader it sounds like. I have the Angelbird now
The Anglebird and other brand readers to include USB4 readers will work fine to transfer data. We just don't have access to the brand's maintenance software when we mix and match card and reader brands. I went with the OWC reader mainly because Exascend hasn't release their USB4 reader yet, and I plan to buy another camera that supports CFexpress Type B so will be using both Type A and B formats soon. Plus I wanted to test the cool idea of the A-B adapter. ha ha

It would give the option to rent outside Sony although im happy with the Sony stable. I will look into this

So card and Reader 419 which is a nice price really. I only have a 320 and 160 Lexar Type A and I could use an another card anyway. Would love a 420 sometimes I have to change cards in the middle of a show. PITA

Endless money pit. But I got 3 big jobs coming
Meeting up with other Sony A1 photographers down in the wetlands recently, I think we all agreed these 1TB cards feel pretty close bottomless, particularly when you are firing the shutter for endless BIF action.
Now, I'm almost feeling like I have 2TB internal A1 memory to wield out in the jungle and on the Motocross track ...kind of 😉 As you mentioned the transfer speeds on the back end sure help the culling response time when scanning/culling through thousands and thousands of bird photos.

I don't find the speed of a card in a card reader to be very interesting. I often shoot thousands of images a day but I don't find the time to download them to be an issue. Download time is insignificant compared to the time required to cull them.
I would like to see how well these cards perform in a camera. Unfortunately there are no cameras that can take advantage of the PCIe-4 lane. Maybe the A1II will (I assume it will), but we won't know for a while. Once the A1II is available the question will be does the memory card or the camera limit the capture performance. Once we get the camera we can make the measurements.

What would be even better is if Nikon could design a camera/chipset/pipeline that could actually write to the type B cards significantly faster than Sony can write to a Type A.
As we see in the recent thread the Nikon is only writing at Type A speeds to its Type B cards. Still nice to have the lower price point though.

Most folks don't count computer time its a big amount of time involved when you have many many images to process and such
All it takes is one brief sojourn back to old UHS-I tech SD cards and we realize how seconds really can matter on the backend, particularly for the long shoots.
M1 silicon, Apple internal SSD, TB3 and 4 ports and super fast and tiny external SSDs have certainly made a difference in my workflow along with CFe Type A 2.0. Next up is Type A, 4.0 and USB4 readers for us greedy for more! Ha Ha
When we do see this new Type A, 4.0 CFexpress come to our cameras, you know I'll be ready 😜
