You only need a 1GB USB flash drive for an ESXi 5,5 installation.

The memory stick is only used to boot the ESXi 5.5 installation, the modules are then re-allocated into memory, and it runs from memory.

So the speed of a memory stick, just affects how fast it read the modules into memory.

USB Flash drives are not as fast as SD cards, e.g. Class 10 etc

We use good quality HP, PNY, SanDisk, or Kingston memory sticks.

You will also need USB 3 to take advantage of really fast USB flash drives, and they tend to be available in large capacities, which are not required to install the OS

see this USB 3.0 stick

Corsair flash drives are fast

Also note the bottle neck of a USB flash drive, is the make of flash, and also the USB2 or USB3 interface. But if this is for the inside of your Microserver, you will also need a small flash drive.

Follow up question:

I already have Esxi 5.5 running on a USB2.0 mounted internally using adapter to MB header.

1. How can I move the current USB image to a class 10 SD Card or USB3.0?

2. Can I simply plug the existing USB or SD (with Esxi) into a different physical box or is there a hardware abstraction layer to contend with?
