I recently upgraded my wife’s MacBook Pro by replacing the original hard drive with an SSD. The performance improvements were just as good as when I did this same upgrade for Lenovo laptop in the family last fall.
Her MacBook has 8GB RAM, a 2.3 Ghz i7 processor, and a 15” inch screen. It was a low end MacBook Pro when we purchased it in July 2013.
The SSD was another Crucial drive from NewEgg.

I timed a few operations to see what they were before and after the upgrade:
Before upgrade:
- Seconds to login prompt 47.8
- Seconds to login 9.4
- Seconds to launch safari 13.8
- Seconds to launch outlook 18.4
After upgrade:
- Seconds to login prompt 44.6
- Seconds to login 4.3
- Seconds to launch safari 2.1
- Seconds to launch Outlook 2.6
The key measurements for my wife was the amount of time it was taking to launch applications. I timed Safari and Outlook, since these are her primary apps to use and the results are amazing. In fact, she laughed at how fast they launched when I first showed her.
