I'm looking into getting a SAS HBA but not very knowledgeable about them. On eBay the best prices for me ( mostly do to free shipping ) are given as 9212 from China, marked as new. Many sellers even posting the same pictures. Am I too assume these are counterfeit? Also I'm planning on getting a bay in my 5.25 slots with a SAS connector but it seems this card has separate ports for the internal instead of a single SAS. Should I be looking somewhere else in your opinions?

So I'm starting a new work and getting a new computer. I think I can finally park my old tower I've been using. I'm currently using it as a Plex Media Server and I also host some Dockers there ( Minecraft server for my daughters, temp work stuff and such ). It has a older but still pretty decent CPU and I did update the GPU at one point so it is not useless junk. My Synology box is almost full and I have plenty of HDs lying around so I'm thinking I should just turn it into a Unraid server where I can run my Plex, Docker and have some more storage. Hardware info for anyone interested: CPU: AMD FX(tm)-8350 Eight-Core GPU: Radeon RX 580 Aorus 8GB Mobo: MSI 970A-G46 Memory: 16 GB Case: Antac P180 ( or something like that ) I also have 2 SSD's in it currently. One for the Windows install ( that I never use ) and the other my Linux OS. They are 250 GB and 480 GB. I guess I could use both as Cache drives. That should leave me with 4 extra SATA connections for the array. I do want to extend that even further in the future. Would this, in your opinion, be a decent beginner Unraid server? What type of drives should I add for my array, I got a few lying around, but they are max around 1 TB in size I think, at least I would get a bigger Parity drive.
