Hardware recommendations

Raspberry Pi 4

A love-hate relationship
  • it is a minimal viable hardware with up-to-date linux kernel
  • a closed source binary blob required to boot aka. ThreadX
  • Known problems:
  • previous RPi generations are not suitable
  • power-supply: quality >3A ; official RPi or Pimoroni
  • USB-SATA adapter needed - decide by tests and recommendations, not price
  • good experience with the Suntronics/GeekWorm X825 board whoc halso had the option to power the directly disk with a 4A barrel connector and the RPi through built in PoGo pins.
  • SDcard: use min 32GB and Endurance type Sandisk/Samsung. If the OS si islow might be the first sign of failure - have a low threshold for ching the SDcard.
  • Disk: use tested 1TB SSD models. Bigger sizes and some models with onboard cache tend to have power spikes and resulting freeze / disconnection from the RPi.
  • a UPS is a must as cold-restarts will corrupt data


  • more power - still energy efficient
  • built in battery
  • screen and keyboard to manage


Home server

  • Still can be a big saving on hosting despite higher power usage
  • Unlimited storage with disk redundancy (ZFS)


  • ECC RAM to prevent data corruption in memory
  • Muliple disks to use a checksumming, "self-healing" software RAID like ZFS
  • Avoid hardware RAID cards - often another source of problems and recovery is not possible with other hardware

Use a minimal VPS with ZeroTier or Tailscale to tunnel services to a public domain
