I have a 13-inch MacBook Pro early 2011 which has 4 GB of RAM and 320 GB of HDD storage. Everything was fine until once time when I run virtualisation and coding using Eclipse, the macbook pro run very slow. It took around 62 seconds to boot and ran virtual machine very slowly. I need to increase the performance of my macbook because I can’t deal with this condition.

After reading in several Mac forums, someone told me to upgrade both RAM and the hard drive. The RAM should be upgraded to at least 8 GB and the hard drive should be replaced with an SSD (Solid State Disk). Although the price is much more expensive than the HDD, the SSD offers four times faster than HDD in the read/write speed.
