Apple's MacBook Pro with 128GB SSD: Performance and Battery Life Investigated
 

While 2009 may end up being the first year that we see widespread adoption of SSDs (Solid State Drives) in notebooks, 2008 will go down as the year that it all started happening.

My experience with a SSD on the MacBook Air was an overwhelmingly positive one. While most application usage performance didn't improve, boot and application start times were noticeably quicker. Also, amazingly enough, battery life was improved by a good 5 - 15% depending on the usage model. I was quite impressed.
