Hello, I would like to let you know that if you use raid with an SSD in any array or any configuration, eventually you will lose performance since the trim command cannot be enabled using raid, this is a hardware limitation so it does not matter actually what chipset or brand you use.
If you want to know more about the trim command please check the following link: http://www.bit-tech.net/hardware/storage/2010/02/04/windows-7-ssd-performance-and-trim/1
Hi, I’m curious as to why you state that the lack of ability to trim on a raid configuration is a hardware limitation. I thought it was a driver issue that Intel was working on? If it is a hardware limitation is it the SSD? Controller?
Even after the OS and SSD are configured to support the TRIM command, other conditions will prevent any benefit from TRIM. As of early 2010, databases and RAID systems are not yet TRIM-aware and subsequently will not know how to pass that information on to the SSD. In those cases the SSD will continue to save and garbage collect those blocks until the OS uses those LBAs for new writes
