Samsung's 3-bit 3D V-NAND enters mass production, cheaper SSDs on the horizon

  1. Solid state drives have long since been the preferred drive choice for those that value speed over capacity yet even as prices have come down significantly over the past few years, SSDs still remain a good bit more expensive than...

    A little confused. will these drives be more or less durable? and does durability refer to the "wear out" factor of SSDs?

    The cells themselves will be less durable but because they can use larger lithography, that disadvantage can be offset. In otherwords, you can at least expect the same durability at around half the cost.

    They aren't scaling back on lithography far enough for Pro level durability though... hard to compare apples until they actually publish costs and durability figures for the models.

    Also, because we can get a larger SSD for the same price, that will help with the endurance as well. While technically that doesn't make the 3-bit MLC lasts longer, larger SSD means we write less to the same block less often and can afford a larger over-provisioned area. For practical example, we could have a 512GB SSD that is 40% filled, compared to a 256GB that is 80% filled.

    And even then guys, the evo was tested in a long endurance test to almost a petabyte of writes, which is more than we could ever commit to a single drive, considering we upgrade them on a basis.

    Doing a fast search on google they updated the results on september and the samsung 840 pro and corsair neutron gtx have survived 1.5PB writes and are moving strongly to the 2PB. The test started on August 20 of 2013 and its still live.

    I'm not sure how you feel on linking another tech site here but it's worth taking a look at

    "Because of this, we’ll likely see the new chips show up in Evo-class drives initially instead of Pro-branded SSDs."
    What? 850pro is already on the market...

    Right, but it's not using v-chips is it? it's talking about NEWER models aimed at CERTAIN grade of drives due to their specification that will EVENTUALLY reach consumers with lower prices.

    "Cheap". I like the sound of that, it has a certain ring to it. "Free" sounds even better but in this case I'll settle for "Cheap".
  10. I have to wonder if these aren't as durable as is being stated, if a day come that it loses all your data, will you really care that it cost less than a more expensive (and more durable) SSD?

    Wonder no longer. It will be inconvenient but not a tragedy because you should always have a backup strategy regardless of what kind of SSD or HDD you might be using. Any SSD or HDD can fail unexpectedly at any time. Nothing lasts forever and there is always the possibility of external forces at work like lightning, fire, flood, etc. We see many examples of people here who lose their data because they didn't think to back it up. Don't be one of them.

    Yeah I think that is what durability refers to.
