The various file systems are not optimized for solid-state drives. The computer industry took decades to optimize the storage of the rotating magnetic medium, but the emergence of solid state hard disk to make these optimization completely void.

Fortunately, the speed of the current solid state drive, follow the old file system requirements as hard as the traditional hard work, and will not have too much damage. But in the near future, we will certainly see the file system designed for the optimization of the solid state hard drive.

Microsoft in the Windows 7 will be optimized for SSD, such as the system will disable the use of automatic disk debris finishing functions in the use of solid-state hard disk. One of my most concerned about is the trim ATA command, which is able to notify the solid-state hard drive, a block is no longer used, SSD can be recovered, into the next step in the loss balance operation.

In the Linux system, you can be very simple to use the kernel IO scheduler disk module to optimize the solid state hard drive. Because there is no shift of the magnetic head read and write, the module is re ordered on the disk read and write to the solid state drive without any sense, and even reduce the performance. Windows 7 estimates will also make the same improvements, but it is not yet announced.
