Inspiron 15 7000 Series 7559 Harddisk Upgrade

Hello together,

Beginning of this year I bought a new notebook with 1 TB HDD and 128 GB SSD.

Unfortunately I found out that the SSD disk that I wanted to use for system and program installation is to small for my use. I had to install programs also on the 1TB HDD which causes some disadvances on creation and Restorage of Backups. Also some of the programs I wanted to install caused problems when they were not installed on drive C.

So I was wondering if it is possible to upgrade my device with a larger SSD with a capacity of 256 or 512 GB. Can anyone recommend some devices that I can install. Are there any Dell service partners that do the installation or can anyone recommend a description about how to do it myselfe?
