Review on ⚡ Highpoint RocketStor 6661A Thunderbolt 3 to PCIe 3.0 X16 Expansion Chassis: Enhance your system with lightning-fast connectivity! by Djmikis Parker

The case itself is very high quality. The fans run at very low speeds and may have trouble cooling the card. The first device immediately blocked my machine when I plugged it in. The second worked, but then I had trouble getting the drivers. The link posted in the documentation didn't work, but I found the drivers elsewhere. The devices would intermittently disconnect, causing the card to squeak. Ironically, tape drives performed better than hard drives on a SAS controller because they are not officially supported. I tested the LSI 9200-16e in a case and it was stable and reliable. They can be bought for as little as $20 with near-universal support, so do the math.
