I bought an XPS 15 9550 laptop in October 2015, with a 500GB SSD C: drive. I need to upgrade that 500GB SSD to a 1TB SSD, but I'm concerned about compatibility with the BIOS, etc. Can you tell me if Dell sells a compatible 1TB SSD drive or if I can find one at Amazon? If you know of a source of detailed instructions for the physical upgrade and for moving the OS and contents of the C: drive to the new SSD, that would be greatly appreciated. With SSD prices appearing to be falling, this sort of thing should be occurring more frequently. Thanks in advance for your help.
