I have had unraid for just under a year now and finally getting my sh@% together and using it for more then Plex. Like a book server, personal wiki and a game server for games like Minecraft to start. I want to add 8 more drives and have used all the sata ports on my board. Now reading a lot about HBA and what I will need. I would like general feedback and also brand and model advice.
Now my math was on the idea to not bottle neck all 8 drives at the same time. This seems like overkill because I can't think of a time when more than two drives would be needed but if you have insight into this please let me know. Rounding up about 5GB/s minimum will be needed for all drives at the same time. So here is what I found that I would need to cover this at the lowest cost. Using a SAS to SATA cable splitter to connect the 8 sata drives.
This has me looking for HBA cards that fit this bill.
1) HBA card
SAS-3
PCIE v3 6Lane
2) HBA card
SAS-4
PCIE v4 3Lane
HBA vs Raid
Im using Unraid so an HBA should do the job just fine. But is there a feature of a Raid card that I could benefit from?
Also there are internal 10 port SATA PCIE cards on amazon but I question the quality.
