Terrific so far. Came up and recognized by Linux OS immediately. Significant speed improvement over motherboard SATA ports. Very happy.

Needed to add another array to a storage server but ran out of disk support so I purchased this card to replace another cheaper device that only supported 8 hard disks. Running TrueNAS RZ2 so hardware RAID was not necessary, just need a JBOD to see the disks. I can recommend this product as I have used it for two months and haven't had any issues. Old pool transferred without any special efforts even after I rewired my backplane to accommodate the new connector type.

Not reliable. I wanted to replace my 9300 16 port for the 9305 24 port support. The 9305 gets so hot that random read errors on various hard drives. I run Truenas Scale with multiple ZFS VDEV pools and if one drive fails in a pool, you go into degraded mode till you replace the marked bad hard drive. I had to swap back to using the 9300 for now till i find a cooling solution for the 9305.Provided you have the space, strongly recommend have fans mounted to the heat sinks.Updated: 4/19/2025 No more bogus HDD failures. For cooling, installed two 120mm fans directly above. Verified firmware is 16.00.12.00 for TrueNas use. Firmware updates can be found at Broadcom web site. Operating system TrueNas Community 25.04.0

To be clear, this is NOT a RAID card, this is an HBA. There is no hardware raid features in this card. That's exactly what I wanted. Cards like these are recommended for non-hardware raid applications like FreeNAS.Card build quality seems to be great, and software support is good so far (firmware/driver updates).

Expensive, but worth is. Bought a cheap card before nothing but problems. This makes my nas faster than my internal hdds.
