Do Intel's 320 SSD's support TRIM in RAID 0?

post #1 of 4
Thread Starter 
I have an Intel 320 120gb at the moment. I am wondering, If I add another and RAID 0, will this thing called "TRIM" be enabled? If not, how do I enable it?

Performance differences I will see? I am usually doing a hundred things at once, like gaming, simple video editing in WMM, a bunch of tabs open and chat applications running.

Also, can someone explain to me in a very simplified way, what TRIM does?

TRIM in RAID has nothing to do with the SSDs. The RAID controller has to support it.

Intel RAID will support TRIM in RAID but does not currently. I do not believe any controller supports it directly currently. There are software RAID implementations that do.

TRIM helps clean the SSD's dirty blocks to maintain optimal write performance.

no, none of them do

trim is a piece of software that evenly distributes drive writes so that the whole drive degrades at an even pace (ssds as people well know it have a limited life time), without trim some areas of the SSD (like page file, edge of your current empty space) will get overused and will stop working resulting in loss of space and loss of speed

you lose TRIM when you RAID 0 SSD's. Most SSD's have good garbage collection so it's not a problem. thumb.gif
