My tests using a Seagate Sold State Hybrid Drive. Model I got is a Momentus XT, 750 SATA 32MB cache. 7200 RPM. The old drive was a Seagate as well, model ST9500420AS 16MB cache at 7200 RPM
* Mbp intel core 2 duo 6gb
* 500 GB st9500420AS
* 16MB 7200 rpm
Tests were done after full restarts of the MBP so app launches were not using app cache.

One thing about CMOS cameras is that they like dust. I have read a lot of posts on how to clean the sensor and I think the best advice is to use common sense. I simply used air and a non-lint cloth to wipe it in one direction. Done. I did use at one time some non-lint Qtip style cleaners as well that I had left over from my clean room days at Motorola. Those help to clean and to be able to apply the right pressure is always a good thing.
The pictures you see here is the sensor of a Canon 5D camera and a picture where I snapped a landscape scene and you’ll notice a hair is in the picture below one of the power lines. I had to clone out this hair on about 20 RAW images using Lightroom’s Spot Removal tool which works excellent.
I snapped a quick pic of the sensor using my iPhone flash to show you how it responds to light. Don’t do this for a long period of time. I simply took a quick photo but I wouldn’t leave the LED on for a longer time than that. The 5D has a sensor cleaning function in the menu settings so it makes it easy to clean.
