i currently have one SSD and one normal wd green.. yes i should upgrade to black

That depends on a lot of things. I would use Resource Monitor to see what kind of load your HDD is under during rendering. If it's very high, then it may help. If not, then it probably won't help much.

When Resource Monitor is open, in the Overview tab, you'll see a section for Disk. Look at the Disk I/O, and at the Highest Active Time. I/O limit for most SATA disks is around 120-150mb/s, probably in the lower end of that for a sequential write on a Green disk, assuming it's sequential for saving a rendering. Highest Active Time is more like "how hard is the disk working to reach that I/O". So you can have very low I/O but very high Active Time, so you've again reached another limit. So if either one of those are high during rendering, a SSD may help.

Obviously check Resource Monitor to check the read/write pattern, but so long as they're doing sequential operations, those HDDs are quite fast (I have a 3TB WD Red [similar to a Green] that seems to like reading/writing at ~150MB/s - quite likely higher than the CPU can render out...) - obviously if it's doing lots of small random I/O then it might be an issue.
