This kit has everything it takes to get into most laptops. SATA 2.5' / 9. Don't get caught with the wrong equipment.
Crucial has one for $154.99 but then the install instructions say I need a 2.5" to 3.5" converter? Please help? Can someone please explain the difference for over $200 and which one they would recommend? OWC has one as well for $189 but won't ship for 19 days. I went to IFixIt and found they have 2 different SSD - at a big price difference. The Mac store tech said I could use any SSD 2.5" internal drive - and he showed me some for under $100 online but now that I'm home looking there seems to be a big difference in SSD Internal drives. In searching for a replacement hard drive for my 13" MacBook Pro mid 2012 - MacBookPro9,2 (Non Retina) - I'm finding mixed information.
