ATTENTION SSD OWNERS: How to prolong drive life.
One disadvantage of an SSD hard drive, is the number of times you can 'write' data to blocks on the drive, before the drive is wore our. On a mechanical drive, you can reformat it by writing 'zeros' to it and virtually making the drive 'like new' again. You can't do this with an SSD drive. In fact, I was told by OCZ support that writing zeros to an SSD drive can actually damage the drive, and was advised to never do that. With that in mind, I have a tip you can use to prolong the 'write' life of your SSD drive.
It's usual for the OS X filesystem to record the ‘last access’ time of every file. This means that every time a file is read, a write is made on the filesystem to record this action. This isn't necessary and can wear a SSD drive out prematurely from thousands of these unnecessary writes to the drive. Download this file and follow my instructions in the ReadMe to turn this action off. Note: this will not affect the "Date Modified" recorded action.
