Why is your first question here an essay question with 15 parts? Especially when a Google search can easily answer it. –  Ignacio Vazquez-Abrams Mar 11 '12 at 5:39

Okay, let's try this from a different angle: Welcome to Super User! We generally expect questions to show a little research effort before they're asked. What have you found out so far? What exactly don't you understand based on what you've read? Moreover, we have a ton of SSD vs. HDD questions already on this site – so feel free to come back with a more specific question. Thanks! –  slhck Mar 11 '12 at 9:04

SSD's are known for their performance ...and cost. They contain no moving parts unlike an HDD. A standard HDD is much cheaper and has spinning disks as opposed to the solid-state memory of a SSD. The current HDDs on the market can hold much more data for its cost too.

Seagate has released a few products utilizing both technologies, but they also have their flaws. Some of its users have complained about its performance whenever the hybrid drive needs to swap between the two types of storage.

The do contain physical parts. They don't contain moving parts. –  Ignacio Vazquez-Abrams Mar 11 '12 at 6:28
    
hah, good catch. I'll quickly edit that out. –  VitaminYes Mar 11 '12 at 6:31

ssd = solid state (chips), hd = Hard Drive, spinning disk.

ssd advantage = faster, lower power, no moving parts.
hd advantage = more capacity available.

That's what a simple Google define tells me. But does not outline the difference... –  Tom Wijsman Mar 11 '12 at 12:36
    
I added the advantages asked for. Other than that I answered the 'exact' question. –  Michael Durrant Mar 12 '12 at 5:23
