I purchased an Aspire 5 A515-43-R19L for my granddaughter over the summer, and she is now trying to use it for digital art, 
animation, and music projects.  When I purchased it, I did not realize 
she would be doing all of this, thinking that it was mainly for her high
 school curriculum. It has a 2.60 GHz Dual Core Ryzen 3 processor and a 
AMD Radeon Vega 3 Graphics controller. It has 4 GB DDR4 SDRAM and 128 GB
 SSD (m.2 nvme).  A computer shop told me that the Ryzen 3 processor would not be capable of handling the types of files she is trying to create, that it would operate slowly.
If
 we add a 2.5 inch 500 GB or 1 TB SSD or HDD, and add an 8 GB SDRAM to the 4 GB that is already there (total of 12 GB), 
would it improve the ability to support what she is doing with her 
files?  She could retain the 128 GB SSD as C Drive and use the 2.5 inch 
as the D Drive to store her files.  Which would be better to add, a 2.5 inch SSD or HDD the empty slot, or just replace the 128 GB SSD with 500 GB or 1 TB?  Adding the 2.5 inch drive I think would prevent us from having to clone the data.
Any suggestions would be helpful
