Options to update the SSD in Late 2013 Mac Pro?

I have the same question. I spent over 2 hours on 2 different calls to Apple Support in the past 10 days. I was trying to buy a 512 or 1024 SSD to replace my 256 in my Mac Pro and decided to try and get one from Apple. Both calls resulted in me being told I could buy one, but only from an authorized Apple Servicer (NOT the Apple Store, btw). They even called 2 local servicer centers while I was on hold and verified this, so I was happily going to spend $600 to get a real 1024 Apple SSD that would be covered by Applecare.

When I called to purchase though (2 different service centers), I was told that when they put my serial number into the computer to order the part from Apple, it would not let them order anything other than a 256 because that is what came with the computer.
Does anyone know why Apple won't let folks get a larger SSD? And *** don't they tell you this when you buy a MacPro? I would have spent the $ for it when I bought if I had known I would be locked into the 256.

One dealer suggested MCE so I checked them out and I will probably buy from them.
I have been a big Apple user/supporter since 1992, but they continue to make it harder to want to stay with Apple. PC's are starting to look a lot more attractive to me.

I've been looking for a long while also and probably will go the MCE path. The Ebay alternatives are shaky, if I read any other Mac associated with a 2013 Mac Pro Just ignore it. Mac Pro is 4 lane for the pcle SSD for sure. If you go to Barefeats and they did have a test with data on the Samsung 941 I believe but I don't think anything came of it.

Hey Craig.

I am also thinking to buy a 512GB SSD for my MacBook Pro 15" Retina (Mid 2014) from MCE Tech. How your SSD is performing? I have heard from some people about the bad service support from MCE Tech. How was your experience? Have you got your ordered item in time? Or you had to poke them time to time?

Please help me in this regard.

Thanks in advance.

OWC's option seems a bit of a kludge using a slower drive and a controller.

I think you are mis-reading the OWC page. They propose to replace the internal SSD stick with their larger-capacity SSD stick. The external case is only for you to continue to use the (perfectly good) original USB stick as an external drive, if desired.

Yes, OWC's does look kludgy . Here are speed comparisons withthe Apple SSD

I had a hard time finding that item, but eventually turned it up:
