Low bandwidth utilization

The usage depends only on customers’ usage, not hardware.
The location plays some role, but not so much.

From the hardware perspective:

  • do not use SMR
  • do not use network attached storage (unless you run the node on this NAS), NFS, SMB, etc. are not supported, only iSCSI can work
  • It’s better to do not use USB drives and use internal drives if it’s possible
  • do not use BTRFS
  • do not use exFAT

That’s probably all. And of course RAID only for Storj makes no sense at all, unless you have it already.
