It is important to note in this video when I discuss the use of USB flash drives and SD cards for installations of ESXi 7.0 the word "not-supported" should be replaced with "not recommended"!

It is not recommended to install ESXi 7.0 on USB or SD cards, because of higher write I/O, and the SD cards are currently suffering because they are not higher endurance. Problems have been found in the wild.

It is technically still supported, eventually, this may filter down through the server vendors.

Some additional information regarding the use of USB and SD cards with VMware vSphere Hypervisor 7.0 (ESXi 7.0), and installations.
