    [UPDATE]
    Two Samsung 840 Pro review samples received by Anandtech have failed.
    [Edit] The non pro 840 Anand had has also now failed along with 4x 840's at [H]ardOCP http://hardforum.com/showpost.php?p=1039330548&postcount=65

    Looks like the drive reliability list should look a little like this.

    Samsung 830 ( 27nm Toggle-mode MLC NAND ) "rock solid reliable"
    Samsung 840 Pro ( 21nm 2bpc MLC NAND ) Not so good - 6 have failed...
    Samsung 840 ( 21nm 3-bit-per-cell MLC (aka TLC NAND) - also may not be reliable - 1 has failed.

    As they continue to shrink Nand, it looks like they are reducing lifespan, reducing reliability all for the sack of reducing cost. I guess the older mature 25nm/27nm NAND SSD's are the way to go.

    "Update: Our replacement 840 Pro also died prematurely, I'd recommend holding off any purchases until we hear back from Samsung as to the cause of death."

    I just happened to be next door to MSY as I read the OP. Picked up two 830 256gb's for $199 each. Cheers

    830s or sandisk for value, or something else with a 5 year warranty imo.

    Intel 520, Plextor pro or Corsair Neutron GTX's all come with 5 year, along with OCZ Vertex 4.. Although ocz had alot of bad publicity from being early adopters /w sandforce I don't think it's as huge an issue as it used to be and I wouldnt be afraid of grabbing a Vertex 4(locally only though :p), considering they are the cheapest ssd available with a good warranty.

    Even though the 840 Pro's come with a 5 year warranty there always seems to be issues with new tech, maybe they will release a firmware update or recall if it's common, they would loose alot of money otherwise offering that kind of warranty on a drive using unreliable nand.

    Btw, samsungs new 840 SSD advertising scares me.(srs).

    I read on samsung FB support that someone tried to register an 840 pro drive for warranty and it came up with 3 year instead of 5. Can anyone confirm?

    Its looking more and more like the 840 Retail bios wasnt the same as the 840 Pro review sample bioses .. so far no retail 840 pro and non pro drives have had any problems so this maybe a very isolated issue with pre release hardware :)
