Linux – Is there Linux support for TRIM on SSD drives

Doing what AndrejaKo suggested above, since this question is essentially answered.

Anandtech reviewed the OCZ Vertex 2 and explicitly mentioned performance after writing without TRIMming, and while not as good as the review for the OWC SSD it's still quite impressive. The site also describes the differences between Agility 2 and Vertex 2. I'm confident the Vertex 2 is a good drive and consider this question answered.

Consider using ext4 with the journal disabled. See this Ubuntu Forums thread: http://ubuntuforums.org/showthread.php?t=1109698. Also, mount with the noatime option so that the last access time is not written on every access.

Note that wiper cannot be used because wiper requires TRIM.

Also note that while running without journalling may improve performance and reduce writes to the SSD, it may also increase the chance of data loss if the system crashes. Here is a kernel.org description of the journal, and an excerpt from Bovet and Cesati's Understanding the Linux kernel, Chapter 17, in which page 29-30 explains the advantage of using journalling. It may also increase the amount it takes to recover from a forced shutdown, as the system will have to perform a full fsck rather than just replay the journal and roll back any incomplete operations.
