It sounds like you're still comfortable using HDD for the bulk of your storage, and add SSDs for fast caches.
Do you think you'll ever get to a point where you run zpools entirely of SSDs? If so, what criteria is important for you? (Raw price per gigabyte? Power usage? MTBF? Something else?)
- rsync 5y agoIn the current landscape I do not foresee rsync.net using all-flash zpools. All of our access is over WAN so disk IO is not that important - it is raw price per GB and even with the "nice" SAS drives we buy ... ~$400 for 16TB is a huge difference vs. ~$700 for 1.8 TB (which is, roughly, the price of the Intel part mentioned in the list of cache drives).
