You also have the option of using ZFS with SSDs as L2ARC read-cache and ZIL write-cache to get potentially the best of both worlds, as long as your disk access patterns yield a decent cache hit rate.
- cshores 2y agoI do something similar as well for my primary storage pool appliance of 28TB available. It has 32GB of system ram so I push push as much in to ARC Cache as possible without the whole thing toppling over; roughly 85%. I only need it for an NFS end point. It's pretty zippy for frequently accessed files.
