    I Know RAID0 is faster than a single drive but the 256GB version of Sammy 840 Pro has significant gain over the 128GB

    Depend on the drive, mobo, and drivers it can go either way; especially if it is a drive that loses significant performance from lack of trim. SSDs have built in load balancing which increases speed as drive size increases. There is also a question of connector (is there a SATA bottleneck which can be bypassed via RAID)
    Also, did intel release the RAID0 trim driver already? IIRC they haven't yet and when they do it would only be for latest gen mobos.

    IIRC, all of the 11.xx series have TRIM support when paired with an 11.xx OROM version AND a Z77 board (no support for other chipsets just yet).

    I bet this is intentional. Why give out free features to older boards

    Dufus has a thread on the board in which he has "modified" a few bytes of the OROM to allow a P67 board to work. Just waiting for him/her to spill the beans! :biggrin:

    Well then, that is proof of the matter than. it is driver based DRM just like with the nvidia drivers. I bet it would be possible to make cracked drivers that would work without need to modify the orom at all

    Someone on hardforum just posted a good idea that hopefully Anand can use to find the firmware version of the dead 840 Pro:

    http://hardforum.com/showpost.php?p=1039341064&postcount=89

    Basically, you run these commands:

    Code:
    set devmgr_show_nonpresent_devices=1
    cd %SystemRoot%\System32
    start devmgmt.msc
    and then use the mouse to choose: View > Show Hidden Devices

    and you will have the usual device manager window except it will show devices that are no longer attached to your system.

    Expand "disk drives", double-click "Samsung SSD 840 PRO Series ATA Device" to open the Properties window, select the Details tab and choose "Hardware Ids" from the pop-up-list. The firmware should then be displayed. Mine shows DXM03B0Q.

    I have two 840 Pro SSDs, a 128GB and a 256GB, purchased from newegg. They both have firmware DXM03B0Q. I have been hammering them for more than a week now and they are both fine.

    I have not seen any new reports of 840 Pro SSDs failing, beyond anandtech's and the poster on hardforum.com. The newegg reviews of the 840 Pro SSDs do not mention any units failing.

    I think the evidence is accumulating in support of Samsung's claim that the 840 Pro SSDs with the shipping firmware (DXM03B0Q) are not at risk for the same failure that anandtech.com saw.

    I still would not recommend for anyone to buy the 840 Pro to use for anything important until some more time has passed and/or we get more definitive news from Samsung. But unless someone reports an 840 Pro failure with firmware DXM03B0Q, it is looking like the shipping 840 Pro SSDs are doing okay.

    The poster from hardforum just posted that he was able to find the firmware version of his 840 Pro SSDs in the kernel log of their testing machine, and they were DXM02B0Q.

    http://hardforum.com/showpost.php?p=1039341659&postcount=91

    Now if only Anand can look up the firmware from the "Show Hidden Devices" trick of the Windows device manager, we may be able to confirm that all the reported failures had the -2B0Q firmware.

    Is it just the 840 Pro shipping with an updated firmware, or does the vanilla 840 get it to?

    I just steered a friend to the Crucial M4 actually, precisely because of the dying 840 Pros.

    However, I also told him to note the Crucial M4 firmware, since some of those have serious issues too.

    Geebus, it almost seems like SSDs are trying to compete with floppy drives and zip drives for unreliability.

    has it been confirmed it's the firmware yet? I'm interested in these and will hold off for now.

    Both of our 840 Pros had the firmware DXM02B0Q in them, just got a confirmation from Anand. That's not to say that the retail units are issue-free, but they do have a newer firmware that supposedly fixes the issues we've been having.

    We now have an 840 Pro with the new firmware as well, lets see if we can kill that one...

    I do hope you redo all the tests, specially the power usages tests.

    It was terribly wrong of Samsung to send to the reviewers a drive that has a different firmware from the one sold at retailers, when different firmwares could have different performance or have different issues.
