Hi, I have this laptop with an HDD of 1 TB and 2GB of ram (4GB internal ram). I want to upgrade it with an NVMe of 250GB and an 8GB module (my user manual says I can have a maximum of 12 GB) but I want to know if I can use the NVMe at the same time as the HDD, so I can keep the 1TB of storage from the HDD. So, my idea is to upgrade my Ram to 12 GB and to have an HDD for storage and the NVMe to save windows.
I'm not too much into tech stuff, but I took some captures, hope that helps. Thanks a lot to whoever can help, also this is my first question on this website (and I'm a Spanish native speaker so if something is misspelled or confusing to understand please tell me) Thanks! I also linked the pieces I want to buy. https://shop.westerndigital.com/products/internal-drives/wd-blue-sn550-nvme-ssd#WDS250G2B0C
<-Ram, this one is the store I'll buy it, my laptop have a 2400 Mhz ram, it will work the 2666 ram? And about ram, on the support chat, they told me I can have up to 20 GB, but I'm not sure, ¿How can I know the limit of ram I can have?
