More that the price of the drive, I can't really believe there are no other alternatives to my model! (at least I could not find one, crucial website says they don't have a replacement drive for my model). I am wondering why is this escenario happening. I got the computer with those 64gb with the idea of upgrading the SSD later, well later has come, I am ready to move but can't.
Is there any other option, than buying a used one on ebay?
The blade SSDs have a custom shape so they only really work in Apple's machines, which is why you won't see many 3rd party versions. Apple has also switched to PCIe now instead of mSATA in the old one. The price is partly to do with the NAND. The cheaper SSDs now use things like TLC NAND.
I don't think buying a used Apple one on eBay is a good idea. They are slower and will have some wear on them.
One thing you might consider is upgrading the whole machine. Your machine would sell for about $600-650. There's the latest 11" and 13" here on the refurb store with 256GB SSD:
Not only do you get PCIe SSD that runs at near 700MB/s as opposed to around 250MB/s:
you get a faster CPU, faster GPU (Iris), USB 3, longer battery life, faster 802.11ac wifi, 1 year warranty that can be extended to 3 years. If you do get $650 for the old one, then it's roughly $369 for the latest 11" with 256GB and $449 for the 13".
The best option for just the SSD is the Aura Pro but for around $100 more, you get all the other upgrades.
