Hello My 2011 MBP just died on me last week. Don't ask we all know what happened to it! Clue GPU. Anyway, I am looking to buy a new MBP 15' mid 2015 as I am not a fan of Apple's 2016/2017/2018 MBPs. I think they screwed things big time with those. So I found one MBP 2015 from an authorised reseller but it's a 256GB drive which is not enough. I need as a minimum 512GB. So I have been looking around at third party PCIe SSDs and came across 2 brands OWC (OWC Aura Pro X) and some brand I found on ebay (Hat SSD). What would you guys recommend? Any other brand you know of? FYI I need to keep the drive inside I don't want some eternal drive to extend the capacity of the MBP. Thank you.
