TexasUnraid Posted May 25, 2020 Share Posted May 25, 2020 So I am in the process of trying out unraid trail as I am wanting to switch over to it. Figured out most things but one issue I am having is lack of sata ports. I have a bunch of Small SSD's floating around and I want to put them into a raid 0 cache pool for storing unimportant things I can replace (like game installs that multiple users can access but are easily replaced so no worries about if something dies), really looking forward to the rumored multiple cache pool feature I saw somewhere. Also be nice to use as a scratch drive for my main system that has a 10gb P2P connection to the server. So the obvious answer is put in a SATA card, I currently have a cheap 4 port pcie x1 card that works fine but is limited to 500mb/s and I need more bandwidth. (I only have 2x onboard sata 3 ports with my dell 7010 motherboard) Doing reading, everyone recommends an HBA LSI card (although finding a particular model that works and is cheap is proving a bit harder). The issues is I also read that these do not support trim on consumer SSD's? TLDR: Need more SATA ports for SSD Raid 0 cache pool SAS cards don't support trim So my question is four fold: 1: Are there any SAS cards that work with trim on consumer SSD's? 2: If not, are there are alternative cards that would work at a similar price point? I have a total of like $100 in my server right now not including the drives and that took years to put together. So the cheaper the better. 3: Is there a way to trim the drives manually by moving them to another controller once a month or so for example? 4: If trim will simply not work, has anyone run a cache pool without trim? What are the effects? The write slowdown is expected and while it sucks, as long as the speeds are still reasonable, I could live with it. More worried about drive longevity of the nand flash. Thanks for any suggestions. After years of trying different options for my server from windows 7, ESXI, Proxmox, freenas, Windows server, windows 10, I have to say that unraid is far far better out of the box then those were after a lot of setup and tweaking. Quickly falling in love with dockers and my inherent distrust of raid fits perfectly with unraid. Although I have been watching ZFS, it might get me on the raid bandwagon. Quote Link to comment
