Technically not. You can boot from an external thunderbolt SSD, which is capable of the same speeds as an internal drive. It’s mildly ugly, but not a showstopper.

But I thought that modern SSDs were supposed to last decades, even under heavy use. Is this actually a real problem?

Does anyone know if TRIM is supported using an external SSD over thunderbolt?

I remember reading it’s not supported over USB3.
