Jason Snell, writing on Six Colors:

Let me state this point clearly in case you missed it: If you think your laptop is slow, and it uses a spinning hard drive, you can probably make it much, much faster by replacing it with flash storage. In almost every case, the storage is the bottleneck, not the processor (or even the RAM, though more RAM can help too).

I interact with exactly one computer that still uses a spinning hard disk. And I’m hoping to change that fairly soon.
