Default Types of flash drives used for bootable USB?

I am just getting started with OpenBSD. I would like to create a bootable flash drive to try. I have seen USB Type C and Type A SSD drives. Would this work for a bootable OpenBSD system?

For installing I use this type: https://en.wikipedia.org/wiki/USB_flash_drive

I've run it from USB2 pendrives in the past.

I have FuguIta, a 'live' OpenBSD, on a USB2 pendrive right now - https://fuguita.org/

Probably I did not understand your correctly. I thought you wanted to create a bootable USB [flash) drive or memory stick to start the install with.
This method of starting the OpenBSD installation is mentioned in https://www.openbsd.org/faq/faq4.html#bsd.rd
Quote:
The OpenBSD installer uses a special ramdisk kernel (bsd.rd) that spawns a live environment running entirely in memory. It contains the install script and a small number of utilities needed to perform a complete installation. These utilities can also be useful for disaster recovery.

The ramdisk kernel can be booted from a number of different sources:
  • CD/DVD
  • USB drive
  • An existing partition
  • Over the network (PXE or other network boot options)
  • Floppy disk
You can install on a traditional hard disk that is inside your laptop or desktop, or on an external removable USB drive. That could be an USB pendrive/flash drive/memory stick or a hard disk inside an USB enclosure, or an external SSD drive with an USB connector.

I don't have any machine with an USB-c connector, but according to https://en.wikipedia.org/wiki/USB-C it is a physical connector and can, besides USB 3.x, also support the older USB 1.0 and 2.0 protocols.

Maybe others, with more modern hardware then me, can report their experiences.

bsd-keith and J65nko: I am glad I asked here and that was alot of information. It answered my questions. It would be nice to have a "Live OpenBSD" OS on an external SSD drive. I would like to try programming on an OpenBSD system and also try compatibility tests on future laptops. I will start looking into this and see what happens. Thanks again!

Not sure fully what you mean by 'live', but there is this bootable CD

https://dataswamp.org/~solene/2020-11-18-fuguita.html

https://fuguita.org/

which can be booted from a USB

I had an ADATA USB3.1 drive that apparently has some firmware on the initial sectors and using it for USB install overwrote the firmware. It became unrecognizeable for future formating or writing another install image. There was a windows based recovery program but it was now longer accessible on ADATA's site and I distrust copies from 3rd party sources.

For this reason I would recommend a USB2.0 drive. Even though they are slower they are firmware free and reliable.

Thanks for the link. I did some reading about this one.

Ok. That is good advice. Thanks.
