ram on SSD will not do anything with system ram. ITS CACHE for your data, nothing more. Should work out of the box. Installation is fairly simple maybe this will help:
by older model (9550) m.2 will not block HDD so you can use both.https://youtu.be/PUSBm1KZZp8?t=277
keeping HDD to save precious SSD disc space is good option
Hey Rdslw! Thanks for the quick response, however, I don't understand what you mean. Are you saying that if I get an older version of the SSD, that I can keep my 1TB HDD in my Dell XPS as well as
put in a 1TB SSD (albeit the SSD is an older version)...? Is that what you are saying? If that is what you are saying, which is the best 'older-version' SSD that I should buy? I didn't think it would be possible for me to have two drives in there!!
