Currently the longest setting is 365 days. This would ONLY work if you used HDDs primarily for storage and want to introduce a "HOT" SSD tier. 

For example, we have customers going on 15 years and we run ALL SAS12 SSDs in RAID10. If we wanted to move 1 year old+ data to an HDD tier just to save money, that would mean approximately 90% of their data would be on HDDs, leaving us with too much SSD storage. That would be a pretty hefty performance penalty.

If you could add longer lengths so we can balance out our capacities that would be a lot better. Or instead of a dropdown of hard coded choices, let us punch in exactly how many days we want. Then it would make sense for us to use it. 

For our environment right now, the only thing we can put in is a faster NVME tier, but that is just a waste of money and negligible performance difference.
