low storage problem: Can I extend my SSD C drive with an external SSD drive?

HP Pavilion x360 - 14-ba030nf

Product number: 3QS32EA#ABF

There is a small space left in my SSD C drive and I wanted to extend it using an external SSD drive. Can I do that? if so, please recommendations on the possible mark or brand that is compatible with my PC? 

Thank you

Specifications for your laptop say you have a 128 gig SSD primary drive and a secondary 1 TB 5400 rpm SATA hard drive for storage.

Its hard to believe you have filled up 1 TB. You can use the extra hard drive to allow additional storage.

I thought that I can't merge SSD drive whith the other existing drives on my computer. Yes, I have 1TB but only the 128 GB of SSD is used in full as a C drive. Any ideas? thank you

There is not going to be a way to do it and just tack it on. You can span or combine 2 disks in the computer but it would trash your OS if you try to include the C:/> drive into it. Nothing you can do with an external drive will be any different or better than what you can do with the internal drives.

The best way to have more space on the C:\> drive is to move all the library folders (docs, downloads, pics, videos, etc.) to another drive and set the computer to automatically save stuff there.
