Just bought a PNY 256GB SDXC card for my MacBook Pro (retina, late-2012) for ~$100 on Amazon. My laptop only has a 128GB SSD in the case. Take away about 30GB for the OS, installed software, and normal updates and I am left with about 85-90GB of free space. That is plenty for everyday files, but I have recently started working with video files in Final Cut Pro X and they are significantly larger.
The current project I am working on is only about 12 minutes, which doesn’t seem very long. But the library (master file) is about 80GB due to all the renders and effects I have used. Once a project is finished I can delete excess renders and effects from the library, then store it on an external drive. But while in use, my laptop does not have enough space to open the library. So I’ve had to keep a portable external hooked up at all times. Not a terrible thing, but it’s tiring to carry an extra drive and always have it hooked up via USB. I can’t move my laptop, or even put it down, without having to move the external with it.
So I got an SD card that will insert into the card reader on the side of the machine. No more cable to plug in. No more waiting for the platter to spin up. No more looking for a place to rest the drive while on the go. A 256GB card will effectively triple my current space and allow me to run a project with ease. Nice!
