I have confirmed that USB3 flash drives can serve as L2ARC caches for
ZFS. I am using a Kingston Hyper-x 64GB USB3 for my tests and it
significantly increased writes between 3 and 10 fold for datasets with
dedup set to verify.
Just thought this would be helpful for deployments where 100% SSD nodes
may be either impractical or out of budget and Ram capacity is limited.
