How much SSD/Hard Drive Space do I need for My Mac?

Unlike Apple’s new RAM baseline of 16 GBytes of RAM, Apple’s unfortunately still skimping on hard disk space with just 256 GBytes of SSD on their non-Pro models (Airs and Minis).

Most Mac mini owners can get an external, fast (and well ventilated) SSD and move their Home directory onto it for around $100. But if you’re on an Air and don’t upgrade to a 512 GByte SSD, you’ll most likely end up having to carry around an external portable SSD.

To “future-proof” your Mac, we recommend a minimum of 512 GBytes of SSD space. Furthermore, upgrading your SSD both unlocks a 2nd channel hard disk I/O channel, speeding up launching apps and opening and saving files. In most cases, upgrading your SSD will also provide you with a full (non-binned) SoC that is approximately 10-15% faster than the binned SoC.
