I think the JetDrive 820 at:

https://us.transcend-info.com/apple/jetdrive_pcie

may be your best bet. While I do not own that particular model, I've owned transcend external drives, USB drives and SD cards and they have never failed on me. If you like the OWC better, I'm not familiar with the language of the website you linked so I'll give you their official website.

Depending on your country, the OWC or even the transcend may be cheaper(transcend is cheaper where I live). Personally, I've had good experience with OWC SATA 3G SSD's too, but I found something concerning in the forums some time ago. You might want to read through it before you decide.
