July 14, 20169 yr I just lost my SSD Cache drive, so looking at the next best way to setup my system to be a little bit better bullet proof. I'm considering a Raid 0 (Mirror) so I don't have to rebuild the cache from backup next time it fails. What is the collective thinking on this topic? Is raid 0 on SSD's a good strategy? Better options? What about using 2 Raptor drives (get close to SSD?). My thought is that RAID 0 increases the throughput significantly. While a single SATA port is limited to 600Gbps, combining two makes for 1.2 GBps of bandwidth. In real life, the DMI bus behind the SATA throttles this to 1GBps, and SATA/RAID overhead reduces that to about 800MBps, but it’s still a significant improvement - I think I got that right. So, in addition to having a redundant hardware backup, I should see improvements...although probably still only internal to the server, since the gate is ethernet at this point... Anyone tried Hybrid Drives? Not sure a RAID 0 hybrid would make a big difference, but perhaps?...? Thanks O wizened ones!
July 15, 20169 yr RAID 0 is not a mirror. You'd want RAID 1 if you wanted a mirror. RAID 0 would definitely not make your system more bullet proof....if one drive fails, you lose it all. Why not just use the built in cache pool feature in unRAID?
