What's the difference between the ssd and hd?
I'm in the process of buying a Mac book pro but wanted to know and understand What's the difference between the ssd and hd?

SSDs are Solid State Drives with no moving parts.
HDs are hard drives that have rotating platters that use a read/write head.
Good luck,

HD are like old vinyl record players inside. Disks and heads that read data, Aluminum disks that are coated for read / write of data
SSD are like memory chips inside a thumb drive. However a bit different

HD = hard drive, several metal platters stacked and data read/written magnetically.
Pro's - less expensive and higher capacity of storage. Can scrub the drive of unwanted data. Unlimited write capability.
Con'- bit rot can cause data and operating system to not be as reliable, mechanical moving parts means you can't move the machine while it's on.
SSD = Solid State Disk, basically memory chips that can store data in a permanent fashion without power (like Random Access Memory needs)
Pro's - faster read/write speeds in most cases. Shock resistant makes them ideal for portable uses.
Con's - new technology issues, one cannot securely erase the data on them, unless it's ground into a fine powder. Limited write capability means they will wear out eventually like USB thumb drives do. Wear leveling (TRIM) is used to spread the writes evenly across the drive to maximize it's lifespan.
If you can respect the machine, take care of it and not move it while it's on, or need to scrub the drive of unwanted data, or need higher capacity of storage without paying a fortune for a very large SSD, then a HD makes a lot of sense.
It really comes down to your privacy, do you want a machine you cannot delete files off of?
Do you want to carry around a machine that has all your dirty secrets etched in it for anyone with the right software to uncover?
A computer is a personal machine, why it's called a Personal Computer. We all do things we sometimes are later ashamed of and want to erase all memory of it.
Can't do that with a SSD, it knows all and you will be forced to destroy the machine to rid it of the unwanted data.

Hmmm, that was, uhmmm, "geek humor" I think 😊
Somewhat. 🙂
One needs a $35,000 machine to destroy the SSD. (or use a local service or melt it in a furnace.)
According to the NSA/CSS 9-12 Storage Device Sanitization Manual, a recommended method of sanitizing Classified Data that appears on Solid State Hard Drives is to “Disintegrate into particles that are nominally 2 millimeter edge length in size using an NSA/CSS evaluated disintegrator outfitted with a 2 millimeter screen”.
