Brian welcomes Andy Klein to the Podcast this week. Andy is the Principle Storage Cloud Storyteller at Backblaze. In addition to the storyteller role, Andy currently serves as the Technical Marketing Director. Andy has been associated with storage and security technology for most of his career and has been with Backblaze for over 12 years.

Brian and Andy discuss storage technology and direction and how Backblaze uses and qualifies drives for use in their data centers. This did prove to be a lively discussion around storage products, but not necessarily data center storage products. Backblaze is a service adored by home users.

Andy is one of the techs behind the Backblaze-generated quarterly storage report. The annual report details failure rates for hard drives and, in a limited sense, SSDs in use at Backblaze. Backblaze is one of the best in being open and communicative about drive usage and failures.

We decided to go live with this podcast and invited our Discord to join. Of course, since it was live, ran into a bit of an issue getting started, so there had to be a restart to get back on track.
