You want to avoid either of those, the first one has a port multiplier, that's and accident waiting to happen, the 2nd one is no longer recommended for unRAID, it can cause sync errors including file corruption and drop disks, the currently recommended 8 ports controllers are LSI, any LSI with a SAS2008/2308/3008 chipset in IT mode, e.g., 9201-8i, 9211-8i, 9207-8i, 9300-8i, etc and clones, like the Dell H200/H310 and IBM M1015, these latter ones need to be crossflashed.
