    Just got my m17x R4 in a week early and first thing I did was download CrystalDiskMark to see how the raid 0 (256x2) SSDs worked. Here's the results:

    Sweet, eh? I'm super excited. This is the fastest, most powerful computer I've ever had!

    Whatever Alienware uses. I have read that they use the Samsung 830, but not sure about that.

    Okay, just went into BIOS and confirmed that the SSD's are indeed Samsung 830's. :)

    Seems that RAID of SSDs will disable the trim which will undermine the long-term using, do you have an approach to solve that or just leave it?

    My theory is if Alienware installs Ssd's in raid 0 then whether trim works or not it must be okay. They'll warranty it for for years so I'm sure it's fine.

    It is okey but just hurts the performance a little bit after some using. Of course it depends on you :D

    It's ok in the sense that it won't cause any permanent damage. A secure erase will restore whatever performance is lost. However, once every block has been written to, it will slow down. You have to determine if the performance gain of striping data across a RAID array outweighs the performance benefit of TRIM. The loss of performance without TRIM is finite, it will not continue to degrade into infinity. Once there is data written to every block, that's as slow as it's going to get.
