Would something like this be a good solution?

Recommended USB drive for dashcam

They give no specific rationale for their 40MB/s threshold; it is a naked assertion. Later, in their longevity section, they say "The Tesla dashcam stores about 2 GB of data in an hour" -- which is about 0.5MB/s, which is about what I calculate when it was one camera, not three.
My rationale was posted earlier:
Their generalizations about drive quality are somewhat reasonable, though I don't know where they got the idea that USB sticks and SD cards don't do wear leveling -- maybe in 1973 they didn't. It is worth noting that "high endurance" cards are a thing, for example microSD High Endurance Video Monitoring Card | SanDisk, which are specifically noted as intended for video surveillance systems.

yep, should be, If you have a lot of FLAC music to put on there too you might need a larger SSD. I have 124GB of FLAC on my second partition.

Just keep an eye on the price. These "endurance" cards are significantly more expensive than normal ones and may be overkill for many people. For example, Samsung claims that their 128GB endurance cards last up to 43800 hours of video recording at ~3.25MB/s. If you assume that your car is either driving or in Sentry mode for 8 hours every day, that would last about 15 years.
A good quality cheaper card will probably be enough for most people ...BTW, if you're looking for a solid MicroSD reader for the car, I love these:
Kingston MobileLite Duo 3C
Solid metal construction and very compact, so it isn't prone to losing contact if you rummage around in the front compartment or drive over a bump. If you have a phone or laptop with USB-C, it comes in handy for that too.

Has anyone actually tested a variety of flash or ssd cards and been able to demonstrate that they either do or don’t make a difference? I’m finding a lot of opinions in this thread and having a hard time making any sense out of it. I’m definitely experiencing a lot of pixelation and green blotches with my USB 2 64GB drive but I’m reluctant to go out and spend money on something faster or better until someone can confirm they have done so and achieved better results.

Nope.
Even with 3 cameras it's not writing nearly fast enough for write speed to be a concern on even the cheapest USB keys for sale- and we've seen everything from those, all the way up to straight up SSDs, that report issues.
It's not the hardware- it's the software.

I bought two of these UGreen card readers (UBS-A/UBS-C) and am using them now. Nice form factor and features, also metal and with a lanyard.

Plan to have one as a backup for when I take out the drive. No need then to even remove the microSD card.
I pulled my flash drive out to analyze the data I've collected so far and can't make heads or tails of it. I have two folders: Recent Clips and Saved Clips.
Under recent clips all of the files are 595 bytes MPEG-4 Movie files that are unreadable.
Under saved clips I have subfolders for each day I've owned the car. I have used Sentry mode every day but the last recording it took was 5 days ago. All of the other subfolders have no files in them. I even have a subfolder dated "tomorrow at 12:55am". How can I have a file dated tomorrow? What does that even mean?
If it makes any difference, I pressed down on the dash cam icon for 2 seconds before ejecting the drive.

Something is wrong if the files are 595 bytes. Typical files are 1 minute of video, occupying 15 to 30 MB. Reformat and try again?
Re. the dates, all times are stored in UTC. If you are in zone -0700, then files recorded at 5:55PM in your local zone will be marked 0055 the "next" day in UTC.
Amazon has 64gb for $10.50 SDCZ430-064G-G46
Amazon has 256gb for $35 SDCZ430-256G-G46
If you have prime now use code save10now to get the 256gb for $25
Looks like a great price but I was not able to get the promo code to work on the 256GB model. Did it work for you?

These Samsung microSD's are on sale today as a daily amazon deal (25% off). Just ordered one. Thanks.
Has anyone tried using a Samsung Pro Endurance MicroSD card for Dashcam/Sentry? Here is a link:
https://www.amazon.com/Samsung-Endu...4HJ5/ref=cm_cr_arp_d_product_top?ie=UTF8&th=1
They are specifically marketed for Dashcam use and claim to be extremely reliable even in extreme temperature conditions. There is one review from someone who claimed they could not get a FAT32 partition larger than 32GB for the TeslaCam but I’m not sure why it didn’t work.

It didn't work because the didn't try using anything but the built-in windows formatting tools- which are not capable of making a FAT32 partition larger than 32GB. Plenty of other tools can though.
Turn on cabin overheat protection and that won't happen if you have at least 20% battery life left.

I've tried the 16GB version of this drive:
https://www.amazon.com/gp/product/B00FDUHD2K/
and this 32GB one:
https://www.amazon.com/gp/product/B00DYQYJ0E
Both have terrible video corruption and problems.
I was thinking I'd try this Samsung 64GB one next.... Anyone have a drive they know works well? This is on a Model 3.
