Msata slot?

When I opened up my laptop (Acer Aspire 7551g) this morning to add another RAM card, I noticed an empty slot next to the RAM slots.
After some searching on the internet I found out that this is probably a mini pcie or msata slot. Is that right?

A picture of it can be found here
It's the slot in the bottom right corner.

Can anyone confirm what kind of slot this is and, more importantly, maybe tell me what I can stick in it?

  1. mSSD for express caching most likely.
  2. Thanks for the reply. Now I'm very new to this stuff.

    I use my laptop for casual gaming, some sound and video recording/editting.
    Is there a hardware part that can be of any use to me in this slot?
  3. its for Adding extra hdd or ssd to get more space.
  4. So extra disk space is the only use for it?
  5. SSD won't add much storage but caching will speed up boot and access times.
  6. Ok so I've got myself a Crucial m4 64GB, Sata 6Gb/s mSATA SSD. Put it in the right slot, started up my laptop, but it doesn't seem to recognize it.

    Can someone help me out here?
  7. Can you see it in BIOS?
  8. Nope I can't see it in my bios, that was the first thing I did.

    However, I did some more research and found out that I'm actually dealing with a mini PCI express card slot. Which means mSATA cards won't even work here.

    I saw a tutorial about connecting an external gpu to a laptop using this slot.
    So that's something I'm gonna look into.

    Thank you all for the helpfull comments!
