hello everyone, well my MBP late 2011 13-inch getting slower lately every time that i start downloading things online. so i decided this is the time to upgrade my RAMs from 4gb to 16gb. and also wanted to upgrade my HDD to SSD. so i've already bought 16gb rams but the problem is the SSD. there are many suggestion and reviews about best quality and the most compatible for MacBook Pro late 2011 and now i'm totally confused so please can anyone help me out. which SSD brand should i go with, i'm looking for 500gb or 512gb SSD. if am going with Crucial which one should i go with Crucial BX 100 ,BX 200 , MX100 or MX 200 if there is a better SSD please share your view.
