Thank you for joining HP Forums. 
I'll be glad to help you 🙂

As I understand you want to use both SSD & the HDD at the same time on your computer,
I had to take some time off and research for you, here are the results:

The Envy 15 has only one drive bay, so you can only have one hard drive or one SSD at a time.
Your laptop supports virtually any standard 2.5" SSD, however, you will have to remove the drive you currently have in there.

The only other way to use both the drives at the same time is by utilizing the mSSD card slot:
Here's your user manual with the details about the same: Click here (look under page 66)

This is the Service manual:

Manual

Look at pages 61 and 66. You can use EITHER a 2.5 inch SATA hard drive or SSD OR an M.2 mSSD. They use different caddies but either uses the single SATA header on the motherboard so 2 drives in the laptop at the same time is not going to happen. Your model came with a 2.5 inch 5400 RPM 1 TB hard drive which is slow by today's standards. 

The other thing I want to point out is that any change to the hard drive configuration requires removal of the back cover, which does jeopardize the warranty. Still, not super hard to do but you need to know. 

Your laptop does not have the sled/caddy/adapter for an M.2 disk so if you want it to be fast for the least investment I would install a 2.5 inch SATA SSD in the bay shown on page 61 in place of the existing hard drive. Then, you could take the original 1 TB 5400 rpm hard drive and put it in a caddy/adapter in place of the optical drive (see p. 48). This would have to be a third party part, but they are widely available on amazon.com and elsewhere. Obviously you lose the DVD drive, but who really uses it these days, anyway. The optical drive replacement is actually allowed by the warranty it is so easy to do. 

Put the OS (Windows) on the SSD and use the 1 TB drive in the DVD bay as storage.
