questions. I've looked at other message boards with varying answers, so I've come to the CB braintrust to hopefully find a difinitive answer. (Also, I'm not super tech savvy and can't afford (literally!) to mess this up.)

1. I want to upgrade my hard drive space on my Yoga 2 13 (currently has 128 GB SSD and 8 GB memory)
2. I've read that there is an extra slot for another hard drive, is that true? I would open it up and look for myself, but have an solid track record of jacking up electronics when I try to mess with them--and I can't afford to mess my computer up
3. If so, what type of slot is it? M.2, mSATA or what?
4. How many GBs can I upgrade to? I've read anywhere from 128 to 500+ are okay.
5. Any brands and models that are known to work?

TIA to anyone who knows the answers.
