The Vast Expansions of Hardware

At the Small Data conference recently, one of the talks looked at hardware advances. It was interesting to see a data perspective on hardware changes, as many of us only worry about the results of hardware: can I get my data quickly? In or out, most of us are more often worried about performance than specs. However, today I thought it might be fun to look at a few changes and numbers to get an idea of how our hardware has changed, in the march towards dealing with more and more data. Big data anyone? In thinking about disks, I saw a chart that looked at the changes from HDD (hard disk drives) to SDD (solid state drives) to NVMe (Nonvolatile Memory Express). These show read speeds going through the list from 80MB/S to 200MB/s to 5000+MB/s. That's a dramatic change, and not one only in high-end arrays. There are off-the-shelf drives you can put in a desktop that read this fast. If you think about some of the early IBM drives, which read at 8800b/s. Growth in disk speed, inside the timeline of our careers, has grown by a few orders of magnitude in read speed. Read the rest of The Vast Expansions of Hardware
