I need to add 1 new internal HD and 1 new internal SSD to my new Inspiron 3000...a few questions.

Hi all, I am a composer of music and just purchased a new Dell Inspiron yesterday that has the following:

1) i7 core
2) 16 Gig Ram
3) 1 TB HD (for operating system and other music programs ...primarily Reaper)

I now need to add 2 more drives:

1) standard 1TB drive for the following sound libraries:

1) SD2
2) RA
3) Silk
4) Voices of Passion
5) Symphonic Choir Platinum (bundle)
6) Spaces

2) SSD drive:

1) Hollywood Strings Platinum


I asked the Dell rep yesterday before my purchase if I could add more internal HD's to this system and they said absolutely yes.

So my question is what brand of internal drives would you recommend for my Dell PC (also where to get them from) and are these something that I as a novice can install easily myself, or should I hire a technician?

Thanks for any assistance!
