Intel SSD 520 - USB 3.0 Wear Leveling & Garbage Collection

Hello,

I was hoping I could get some more educated opinions and preferably facts about a wear leveling concern I'm having with my SSD.

Usage: Running multiple VMs off a SSD connected by USB 3.0.

Device:Intel 520 120GB SSD (SSDSC2CW120A3)

Concern: I am unable to find whether or not the device itself will do wear leveling independently since I have been told USB devices cannot pass the commands to the device and also if it its able to do garbage collection while on USB 3.0.

Thanks for your time,

Adam
