Hi all, I am really happy to say that I have removed this SSD from my SAMSUNG NP530U4C already. And my laptop is now work great like new. I have the same problem as everyone who end up in this thread. My machine boots slow, like 5 minute at least. I have tried every possible way on the internet and found this thread yesterday. I decided to remove it immediately. Now my beloved laptop take only 4-5 seconds to boot into Windows 10 on my 256GB SSD. In case that you are the owner of SAMSUNG NP530U4C like me and not sure how to do it yourself, please take it to computer shop and tell them to follow the disassembling steps here: https://www.ifixit.com/Guide/Disassembling+Samsung+Laptop+Ultrabook+NP530U3B/23322 and the SSD chip is on the backside of your main board as in the picture below (at step #16) Hope this comment help confirm the solution. It just work really great for my case. I wrote a blog about the solution here!
