I don't feel like upgrading my hard drive or splitting off a partition on my existing hard drive. That said, it has a SD card slot, and I'm thinking of installing onto that partition and boot off of it instead whenever I feel like it. Since I have a desktop tower, the notebook computer is mainly served as a machine in which I edit software code being hosted online somewhere.
Would a 128 GB SD card work well enough from your experiences or stories you've heard? What about booting from the SD card? I've searched on Google and saw that the speed may be slower than even the slower magnetic HDDs.
