    Is this the same as an 840 or 840 Pro or unrelated? I bought a machine that has this drive. I don't have any use for it so in selling it I'm wondering if it can also be advertised as one of the two consumer drives.

    The 841 should be equivalent to a evo 840 (TLC nand) if I am not mistaken. msata I believe?

    Rather unrelated:
    - it hasn't officially made it's way into the retail market
    - it isn't supported by Samsung Magician software.

    I have no idea about technical similarities to the 840 series though. There is also a PM851 Series successor.


    Why don't you have no use for it? Do you own a 1TB Evo?

    It's a regular 2.5" SATA drive. I neither need the speed nor capacity. The Intel 320 160gb is still serving me fine.

    Its SSD with 840 Basic TLC NAND and MDX Samsung PRO controller ,which is slower 100mhz from EVO controller.
    Do you need lower power consumption? because if you do ,you may be surprised how much power consumption went down in last two years.
    I will not confirm but i would try if i were on your place.

    Thanks for that info. There are some drives other than Samsung I prefer for power consumption. The Samsung's tend to have low idle consumption like many of them, but the consumption under load is a bit higher than ones like Toshiba Q Series.

    I didn't know Toshiba is good with power.I saw now.
    Samsung 840 Basic and Toshiba are about same in power consumption but what i am confused is that EVO is not so good.

    Interesting graphs and not consistent with my own observations of both the M500 and the EVO, albeit the mSATA versions. Perhaps it depends on disk usage during the testing but, under idle conditions on my Samsung NP900X4C, the EVO resulted in more than 10% lower system power consumption than the M500.

    No ,your observations are good.
    I talk to Chris from TT and he tested EVO msata 1TB but he didn't made graf.EVO 1tb msata manage to get 291 minutes.So it seems EVO msata is better then his 2.5" brother ,i dont know why.
    I bet 250GB version of EVO msata would last at least 310 minutes what would be record.
    They had 120Gb version in review but they never made power test.Which is really something i would love to see.I think that for msata reviews power consumption is more important then few more mb/s in chart that some SSD gives.
    There is one review site with biggest msata review base,they even have Samsung PM841 review ,but its useless ,they don't have any kind of power consumption test.
