I’m deconstructing my oldest personal ZFS pool after more than four years of flawless service. It was built with 4× 3 TB WD Blue drives for Clara’s and my Plex media backend, running on an HP Gen8 Microserver.

She’s being upgraded with 2× 10 TB HGST drives in a ZFS mirror, for a few reasons:

  • more capacity,
  • performance,
  • to free up two drive bays, and
  • because I trust mirrors over RAIDZ-1 for these larger drives.

Thanks FreeBSD, GELI, ZFS, Western Digital, and HP!

And for those wondering about the name, it’s a concatenation of Tanaka Asuka’s name from Hibike! Euphonium, everyone’s favourite bespekled tuba player. Kyoto Animation are known for their high production values and beautiful art, but their rendition of this series by Ayano Takeda and Nikki Asada was something else.

The official key visual above was drawn by Akaya Nagahama.
