Unless you've got databases writing to the disk all the time on your VMs, I wouldn't really worry about it. I do, however, recommend skipping the 120GB model.
I reckon during normal operation, you'd have around 5-10GB writes per day (less if you've got lots of RAM allotted). At 3x write amplification (which is pretty high), that's 5-10TB a year per VM. Even looking at worst case scenario, the 120GB model should be capable of 120TB worth of writes so that's at least 4 VMs for 3 years or 12 VMs for 1 year. With the 250+GB capacities, write endurance is high enough that it's unlikely to be a concern for low-load VMs.
