Good afternoon, per the macsales.com website and from personal experience, the LG Blu-Ray Multi Drive works really well up to 16X BD-R, 16X DVD+/-R, 8X DVD+/-RW, 8X DVD+/-R DL, & 48X CD burn speeds. Supports M-DISC extended life media. Part: WH16NS40. I replaced both optical drives on my 2012 5,1 with really good results, best of luck.
