An SSD crash course: What you need to know


The idea of a solid-state disk has been around for a very long time. Essentially, an SSD is persistent storage media constructed using transistors rather than an electromechanical disk or tape. SSDs have been holding the firmware for our switches, routers, cell phones, calculators, and just about any other kind of nondisk persistent memory for easily 30 or more years.

This type of application for SSD hasn't been possible until recently due to the tremendous difficulty involved in constructing very large SSD memory modules that are cheap, reliable, and fast and that have a long lifetime. We're still working to overcome some of these challenges, and being aware of them is key to implementing them successfully.
