Interesting to know if someone have used such thing > with debian. Either you care about performance or you use RPi - not both. USB3 only helps if the data pipeline can handle the load. A quite cheap (but not too cheap like RPi) option is Olimex LIME2 with native SATA port: https://www.olimex.com/Products/OLinuXino/A20/A20-OLinuXino-LIME2/ A more powerful option with native SATA is Helios64 at kobol.io - but beware that (like Pine* devices, but unlike Olimex) they are built only in batches as enough orders come in, so you have a higher risk that the product you buy might go out of business even before it gets supported in Debian - as seemingly happened with their previous Helios4 device. (one nice feature of the seemingly abandoned Helios4 was that it used ECC memory - cheapest device that I know of doing that!) I am a happy LIME2 user since some years. I don't use RAID though. - Jonas -- * Jonas Smedegaard - idealist & Internet-arkitekt * Tlf.: +45 40843136 Website: http://dr.jones.dk/ [x] quote me freely [ ] ask before reusing [ ] keep private
