How do you optimize(garbage collection) SSD's when used in a RAID (0) configuration?

I have been using 25M, 160 gb SSD as individual units and understand the need for the TRIM function. I am doing a new build and would like to configure two of my SSD'd in a RAID 0 configuration, and I am assuming the same reasoning holds that some form of "garbage collection" TRIM type optimization is also required. I'm a newby so any help or references would be appreciated. thanks

Welcome!

Long story short, GC works when the PC is in idle mode, so try not to shut down your PC after long hours of deleting/moving files. I have a pair of 510 series in RAID 0 and I've seen the transfer rates go from 990MB/s to 720MB/s, after a couple of nights on and in idle state, the speed was completely recovered.

Also keep in mind that Intel is most likely releasing a TRIM support for RAID 0 in RST 11.5.

Well thank you Xeneize for the fast response to my question. If it is permissible to ask a few related questions they are as follows:

* Your answer prompted me to check my power settings (wondering if I changed them when I went to an SSD a few years ago) and I checked shutoff hard drive after 20 min,sleep after 30 min, allow hybrid sleep> ON, hybernate after 840 min{for out of town trips}. These were intended to save the life of my previous Raptor hard drive. Looks like I should be changing these and prolong hard drive off and sleep times. Any suggestions for duration?

*Will the enhansed TRIM program you reference be a separate release by INtel (how does one get a "RST"), will it be incoporated into an update to the Intel toolbox, and will it be released as an update to win 7. I did just update my INtel Toolbox when checking my new 520 purchase. Just in case you have some thoughts on these issues as well.

I did check that you gave me a correct answer,thanks

Thanks in advance for your efforts and help,

Best regards,

DANY

No problem friend.

You should for sure disable Hybernation if you are using SSD, it's a best practice, in fact here's a great guide to help you optimize your SSD:

As far as Intel Rapid Storage diver to support TRIM, it will be their next release of the software/driver, most likely will be included with the Intel Toolbox, here's a good source:
