I'm not a Mac guy, but I believe I can still offer some good input. Since you have a non-retina version, there is no SSD. My advice is to swap the SATA HDD for [https://www.amazon.com/gp/aw/d/B01F9G43WU/ref=s9_simh_gw_g147_i1_r?pf_rd_p=53aae08a-b09f-44f4-8454-4ca9f1819faa&pf_rd_s=grid-unrec-3&pf_rd_t=Gateway&pf_rd_i=mobile&pf_rd_m=ATVPDKIKX0DER&pf_rd_r=GWF8JQZDD9HRZXZ3D4W9&pf_rd_r=GWF8JQZDD9HRZXZ3D4W9&pf_rd_p=53aae08a-b09f-44f4-8454-4ca9f1819faa|this], and put your old HHD (or a new one) in a caddy for the DVD drive. You must do some research before purchasing SSDs, because many brands tend to overprice them. I have seen '''250GB''' Samsung 850 pro's for as much $129, when I could get a '''500GB SSD''' with the same performance for the same price! The sandisk SSD in the link above is available in 240, 480, or 960GB and offers the superior MLC flash, and a few tricks up it's sleeve. Hope this helps!
