Reason for professional upgrade?Conceptually, hard drives work a bit like old-fashioned record players.They contain spinning platters. A part called the actuator moves a tiny arm that floats a miniscule distance above the surface of the disk platters.It is not the raw speed of the SSD, it is how it works.A traditional hard drive is like a record player, when you send data from the HDD to the CPU the computer/Laptop has to find it, it hunts around the platters looking for all the data. With an SSD, there is no waiting, this is because your data is effectively in a spreadsheet. The SSD knows where it all your data is instantaneously.No waiting. No spinning beach ball.
What Can I Expect After Replacing MacBook Pro’s Hard Drive?

• Enjoy a longer life span for your computer. No moving parts, and if you drop your laptop, no parts that can be easily damaged.
• Expect a speedier notebook – SSD are powered by electricity, which moves at an incredible speed at a fraction of the power of a regular old hard drive.
• Take advantage of more mobility – SSDs are smaller and lighter
• Now, you’ll have less “major malfunctions” – HDDs have to read files in a sequence. As the disc becomes crammed with data files being written across many sections at once this causes fragmentation.
• Files will load at the speed of light. SSD do a great job of accessing data simultaneously, which means your files are read more expediently.
