SSD Upgrade on Late 2013 MBP Retina

Voiding the warranty still is a grave risk. While I cannot speak officially for Apple, there has been no official announcement that you can change it yourself without voiding the warranty.

STate's of damage is cause by the service, so as long as you don't break it and the drive doesn't cause cause damage then you're good. Everything except the drive will be covered.

f) to damage caused by service (including upgrades and expansions) performed by anyone who is not a representative of Apple or an Apple Authorized Service Provider (“AASP”); (g) to an Apple Product that has been modified to alter functionality or capability without the written permission of Apple; (h) to defects caused by normal wear and tear or otherwise due to the normal aging of the Apple Product, or ℹ if any serial number has been removed or defaced from the Apple Product.

My warranty has expired and my 512GB SSD is going to die, so I was wondering whether at this point it would be more convenient to shell out a few hundred bucks to get the faulty piece replaced by Apple or to buy a 1TB SSD (if there's any around) and replace it myself with an iFixit kit. Any suggestions?

being they are proprietary, I'd say yet. I find it odd that an ssd is failing that soon. I'd check for service extensions or see it you can get them to swap.

Apple will replace with original equipment for a fee. You are free always to self-service (OWC sells SSDs and pentalobe screwdrivers), but Genius Bar may consider the self-service grounds to refuse future service (if you broke something else, they do not want to be blamed for the side-damage). External storage may be your best solution.

Apple does not extend expired warranties.

But ... this is not saying you are foolish to buy a larger SSD on your own and following iFixit instructions if you are ready to accept the risks.

I Thought I read that it was a 2013 model. Idk why lol. I had just woke up when I posted. If you have a mid 2012 or older with a 2.5" it's way cheaper and only a 5 min swap.

I know I'm late to the party and you probably have already discovered this but OWC has come out with a SSD replacement for the mid 2013 macbook-2015 version. Check it out on their website at www.macsales.com
