I love speed....it's one thing I love about flying. The plane I fly can fly at 85% the speed of sound. It can go ZERO to 150 MPH in under 12 seconds. I love speed.
My current Macbook Pro is a 2.4 GHz Core I5. It was nice when I bought it. But I wanted more speed.
I initially installed a 7200RPM Western Digital 500 GB drive. It was faster than the stock 5400RPM 320 GB drive. Still I wanted more.
SSD's....Solid State Drives...can be super fast....but also super expensive. I paid $70 for my 500 GB 7200RPM drive. A similar sized SSD would be over $1200!!! Ouch. I found a smoking deal on a 120GB Intel SSD this week and bit the bullet...as a birthday gift to myself. In order to pay for it I have picked up gobs of overtime in the last month.
I installed it last night. Wow. I am still shocked about how fast it is. With my 7200 RPM drive I would wait 3-10 seconds for Safari to open. Now it's instant. I haven't installed Windows 7 yet. Everything is zippy. I'm going to yank my DVD drive and install the 500 GB 7200RPM drive there next.
Whenever Kelli's Macbook gets "slow" I'm going to throw an SSD in. She has a 5400RPM 160GB drive in there now. She maybe uses 40 GB total so a 120GB SSD would be plenty.
