It looks like Intel has finally released a version of RST that supports TRIM in RAID-0 arrays...the problem is that they've blocked older chipsets from being able to use it, including those with X79 chipsets!! Isn't it nice to have Intel looking out for you and "strongly encouraging" you to "upgrade" by forcing you to by a lesser board to overcome an arbitrary software limitation? I'm beginning to wonder why Intel even bothers making a single processor version of LGA2011...they'd be better off by limiting LGA2011 to dual Xeons. Oh, that's right, then they'd have no dumping ground for all those Xeons that are defective and would have to lower the prices on neutered low end Xeons to sell off all the defective dies. I think that's all the single processor LGA2011 market means for Intel...a convenient garbage can to allow them to get something for a defective chip and protect the higher margin of the "Xeon" chips. They treat this market like a garbage can as well...
