SSD in Aspire E15

Hello,

I have a Aspire E 15, E5-553-T01Q.

I am happy with its performance but feel the local hard disk (SSD) is less for my requirements.

I want to know if its possible to add more SSD ? OR Replace Existing one with a higher capacity ? AND how much maximum capacity upgrade is supported.

Thank you in advance.

BR,

Amol.
