I have an old Dell H200E that I bought back in 2015. It is serving it's purpose, but I'm wondering if there is something better that I could run. I have a Dual Xeon E5-2670 that I am using for Plex and an SMB file server. The server has the H200E connected to both controllers of a DS4243 (with IOM6 controllers installed) with a mix of 8TB SAS and 4TB SATA disks. Storage is managed by ZFS. Is there a need/reason to upgrade the controller? would I see better performance from something else? More features that I didn't know I needed? Or should I just stay with what works?

There are better ones like the newer LSI/BroadCom 12G controllers (9300, 9305)
but with mechanical disks I see no reason to upgrade.

The LSI 2008 chip is PCIe 2.0 x8 what allows 4 GB/s. Each 6G miniSAS connector (4 disks, each around 500MB/s) gives around 2GB/s. If you connect both you are at 4GB/s also.

A mechanical disks allows up to say 200MB/s. With 12 disks you are at 2,4 GB/s so your disks are slower than what the HBA allows. I also doubt that your server is capable to process 2GB/s. You also need 20G connectivity to process such a data rate over your network.
