Broadcom/LSI 9305-16i is a 12Gb/s SAS, PCIe x8 HBA that reliably reaches high IO (multi‑hundred‑thousand to ~1.5M IOPS in reviewer tests) but has thermal and flashing caveats for desktop use; great for server racks and ZFS/IT-mode passthrough, less ideal in low-airflow desktops without added cooling.
For homelabbers or sysadmins needing 12Gb/s SAS, PCIe x8 HBA with IT-mode for ZFS and heavy I/O; avoid if you lack server airflow or firmware‑flashing experience.
