Hey guys. I've got my Mac Mini-- mid 2011 - see pic for specs. I already upgraded it from 4GB RAM to 8GB but haven't really noticed a bump in speed like I thought I might. Just wondering what would be my best bet for upgrading the SSD. I think I can handle it, I found a good DIY video on OWC, unless there are better ones? Also what size should I go for, 128GB? I don't do a ton of crazy stuff, just some photoshop/lightroom so I figure I can put most my apps on the SSD and could I still use my other 500GB drive as an internal drive or would I have to use it as a USB external? Thanks for any advice and tips guys!
