Advantage of installing ESXi on a USB Flash Drive over Local Disks ?
In my first installation of VMWare, I installed ESXi on my 4GB Flash Drive and I keep that USB on the VMware box all the time.
That said I started thinking, as I prepare to set up another VMWare box, if it is really necessary to create ESXi on the flash drive ... it comes with the hassle to keep a duplicate (which I have not done yet). Since I am doing RAID 1 on two 4TB HDs, space is not an issue and redundancy is already there. So I wonder now if I should install ESX on the local hard drive.
Thanks.

Yes, you can use 2GB. (make sure it's a good quality, e.g. HP, SanDisk, Kingston).
Technically you would need two hot spares, as disks of similar age, usually fail at the same time, and when the RAID is Rebuilding, this is also the most stressful time for a disk....

'Do you also keep spare disks' ---> if you are referring to local HDs, Yes I have set up a hot spare available to two HDs on RAID 1 on LSI MegaRaid SAS/SATA Controller.
You mentioned ESX OS size is barely 1GB. Can use 2GB USB Flash drive then instead of 4GB?
