I recently moved to a 15-inch MacBook Pro as my only computer. While I loved my Air, I simply needed more power and screen space than the 13-machine could offer.

However, the Air ruined spinning hard drives for me, so I installed a Crucial 256 GB m4 2.5-Inch SSD. Once you use an SSD, you really cannot go back. The speed and power savings over a traditional hard drive is really worth the money.

At 6Gb/s, the m4 is crazy fast:

• 500 MB/sec sequential reads (at 6 Gb/sec)
• 260 MB/sec sequential writes (at 6 Gb/sec)

With a 3-year warranty, I'm not worried about a failure during the life of this MacBook Pro. If you're looking to speed up your computer, this is a great way to do it.
