arobinson888 Posted September 7, 2015 Share Posted September 7, 2015 Hi, When review my logs this evening I noticed something odd in smartctl. It was reporting my drives as being 6 GB/s capable but only running at 3 GB/s. When checking on the specs of my motherboard I found out that I had plugged my drives into the wrong (slower) ports on my motherboard. What I am wondering is, can I just move these drives over to the proper ports and everything will just work, or do I need to plan on rebuilding my array if I decide to do this? Could I potentially just move the cache drive for now without screwing anything up even? Current motherboard is a TYAN S5512 with 8 x 6GB/s ports on a LSI SAS2008 and 2 6Gb/s with 4x 3Gb/s ports on a Intel C204. My plan being to move either all drives to the LSI controller, or some to the 6GB/s ports on the Intel and the rest to the LSI. Currently I have 4 disks in this system (1 x parity, 1 x cache, 2 x data) Thanks Quote Link to comment

Move them to the ports where you want them and it should all 'just work'. Quote Link to comment
RobJ Posted September 7, 2015 Share Posted September 7, 2015 However you won't see any performance difference, except possibly for a fast SSD. 3 GB/s is more than fast enough for all but the fastest drives. Quote Link to comment
