Suggestions for a 10-20TB linux compatible storage array ?

[Tyler Aviss]

I agree with Lennart on the USB thing. For a large dedicated storage array,
USB is not going to be a reliable choice. Even USB3 can have issues.

If your hardware doesn't have an eSATA port, the adaptors are usually
affordable.

The best of both worlds might be some NAS storage solutions that also
support eSATA (and/or USB)
