It's storage on a chips instead of on a optical harddisk, overall much faster than conventional harddisks.

So, instead of having mechanical disks rotating inside the enclosure there are memory chips inside.
Conventional disks can be damaged much easier by shocks, HDD are a bit like an old fashioned record player, if you hit it the needle hits the record and you hear a screeching noise, if this happens to a HDD it will be permanently damaged but there are sensors inside to prevent this.

SSD don't have any moving parts in them and are much better.Edit: And more expensive/Less cheap.

Special School District (SSD) is a nationwide leader in providing special education services and technical education. They are also a world leader in the burgeoning field of Acronym Misappropriation... :D

SSD stands for Spherically Structured Dilythium. It's a materials technology, one from a long line of such, that has been harvested from an alien spacecraft which crashed in New Mexico in 1947.

Initially used only in military applications, since the early 2000s, government scientists have been making SSD available to private companies for consumer use. Now days, computer manufacturers - and especially Apple - have been harnessing it to make their systems faster and smaller.

Is it safe? We just don't know.

This. Having a SSD with your macOS on it means bringing your boot time down to 15 secs or less. Faster loading time for applications installed on the SSD.

If you work with large Incompressible data files and heavy apps, you may want to consider getting a SSD. It will make your machine work much faster.

OWC .. waaay overpriced! Get a Samsung 830 ssd instead, it's actually what Apple put in their new macbooks now. I own one myself, it's stable and fast.
Just a quick example, not an endorsement, though I like OWC... :D

The OP's question has been answered in post #2 and this thread will continue to attract off topic posts so I'm locking it.
