Robert,
Hey, there. Hope all is well.
If you're just providing the base OS installation images, I would suggest using 32 GB USB keys. They're reasonably priced, if you accidentally throw one away, no big deal. I use 32 GB USB keys for Virtual I/O Server installations and IBM i installations on full-system logical partitions. They're much faster than optical media and more reliable over time, plus I can leave a copy with the client. I just charge them for the media.
If you need to provide the full, extended set of USB images for IBM i, then I would recommend using a 64 GB key. Larger keys aren't really needed for AIX or Virtual I/O Server since they don't have as comprehensive a set of LPPs and most of the time it's better to download/stage/transfer the latest images directly from ESS and FixCentral. I know with PTFs for IBM i, you can stage those in advance; if you put them on the key, you can just import them into an image catalog. (You probably already know this; just providing a complete explanation for those who may not know.)
As for specific brands, I use Microcenter's house brand 32 GB USB 3.0 keys and write the install images with Alex Page's USB Image Tool (Virtual I/O Server, AIX, Linux) and the IBM USB Utility (IBM i). Note that you can also use Balena Etcher or a variety of other image-writing tools, including dd, but I've had the best success with the USB Image Tool on Windows.
I would also recommend using a USB key with a rigid body instead of one of those telescoping bodies. You can more effectively label the key that way without a lanyard or string tag.

Subject: Recommendations for USB flash drives for a Power 11.
If you plan on installing or upgrading IBM i, AIX, firmware, VIOS on a Power 11, what recommendations do you have for USB sticks?
What size?
Insist on USB 3.0? or can you use higher?
