I've got an old DroboPro which refuses to mount in Mavericks. Out of warranty, and at its best Drobo tech support was not so great. Its filled with a mishmash of drives 750GB, 1TB, 2TB, 3TB. I'm looking for a simple alternative. I've got an old 10bay eSATA enclosure which works fine. Would prefer not to have to invest in NAS hardware. Any solutions? Performance/Speed is NOT an issue as I'm using it for deep backup. Dual Disk redundancy would be great (i.e.: two drives can fail and I still don't loose data) Thank you!
