Drobo S vs Gen 3

I have a Drobo Gen3 that has been amazing for me. A friend recently gave me his Drobo S. Is it worth migrating to (no direct disk pack migration available)? Is the S just as fast and reliable? I DO gain another drive bay and that would be useful, but are they otherwise equivalent?

The extra bay is absolutely not worth being limited to 16TB instead of the Gen 3’s 64TB or being stuck with max supported drive size of 4TB instead of 12TB.

See the chart here: Maximum Volume Size and Largest Size Drive (drobo.com)

No they’re not equivalent the Drobo S is older, slower, and less capable.
