They are needed if you are using a real OS like ubuntu server/desktop/mate 20.04 LTS 64 bit. There's NO support yet for USB Boot on Rpi 4 other than raspbian 32/64 bit OS's.I'm using the SanDisk 128GB Extreme PRO USB 3.1 Solid State Flash Drive, $40 @ Amazon - amazing performance. No SD needed with the new beta boot eprom update
After checking multiple benchmarks about your Sandisk 128gb Extreme Pro USB 3.1 SSFD, you could've got 3x faster reading/writing speeds for the same money with a Kingston A400 240Gb SSD drive and a USB3 to SATA adapter(UASP and Trim support under raspbian) w/ ASM1153E chipset(Eluteng).

No, the Pi does not corrupt sdcards when you power off. Someone is telling you nonsense.Does the Pi corrupt the sd card when you power it off? That was my problem with the original Pi. I was told that using a thumb drive prevents this problem.
The issue is or was that Pi would crash often and there was no way to reboot it. It wasn't a power issue. This turned me off of Pi to use for anything useful.No, the Pi does not corrupt sdcards when you power off. Someone is telling you nonsense.
With good quality storage and a good quality power supply like we can get these days, the Raspberry Pi is very reliable.
I find that annoying too. These days you can get "Smart Plugs" which are a wifi-connected power switch. That could offer out-of-band power management for you?The issue is or was that Pi would crash often and there was no way to reboot it. It wasn't a power issue.

Used several different SD cards and only one passed the Pi speed test. This was a Verbatim16GB Card. However, used 4, all worked at first but corrupted later? I read you article promoting the Silicon Power 3D NAND Card as the best tested. This failed the Pi Test and confirmed as not fast enough? It seems to be really difficult buying something on line? For all I know these could be counterfeit? I think I bought them on Amazon. At the moment I've only got one card operating on Pi and this is the Verbatim 16GB and the only one I have left.
I've completely given up buying sdcards online. It's impossible to separate legitimate product from counterfeit.What does one do now? Is there anywhere out there a guaranteed quality card can be purchased?
I don't know how the manufacturers are handling warranties, but I know in the CCTV business we have to use special micro SD cards to prevent them from melting in a security camera. Western Digital Purple cards qualify and the SanDisk High Endurance cards qualify. I've not used the Samsung Pro Endurance cards, but just from comparing specs they look to be similar to the Western Digital and SanDisk cards and would probably work too.A number of SD card manufacturers are putting up disclaimers on warranties, They are saying that applications with high write to read ratios are NOT covered under the lifetime warranties! One such being an automobile camera with 2 lenses and image sensors. All the years of touting lifetime warranties now come with an implied disclaimer about writing too many times to an SD card. Anyone hear similar or different? SanDisk, Sony, Lexar, Transcend, etc. what are your official policies on lifetime warranty?
