Going to buy my first macbook air 13" next week. Still debating on the 256. I see people saying 128 is enough, but still leary for some reason. If I go with the 128, what is the best external USB 3.0 HD??
If you will go with the MacBook Air, you will definitely want an External HDD.
But it all depends on what you have.
If you're doing standard things such as web, pages, keynote and numbers, I'm sure you won't need an external HDD.
I bought a USB 3.0 2TB Western Digital "My Passport". Read and write is about 100 MB/s and it does not need external power supply.
