The document discusses the benefits of using solid state drives (SSDs) over traditional spinning hard disk drives. It notes that SSDs provide significantly faster random read and write speeds compared to HDDs, can handle millions of files quickly, offer lower power consumption, and are a good starting point for most use cases. The document advises focusing code and infrastructure on utilizing SSD capabilities like random I/O rather than using technologies like NoSQL databases and sharding that are designed for HDD limitations.
