Intel 335 Series SSD Equipped With 20-nm NAND

crookedvulture writes "The next generation of NAND has arrived. Intel's latest 335 Series SSD sports 20-nm flash chips that are 29% smaller than the previous, 25-nm generation. The NAND features a new planar cell structure with a floating, high-k/metal gate stack, a first for the flash industry. This cell structure purportedly helps the 20-nm NAND overcome cell-to-cell interference, allowing it to offer the same performance and reliability characteristics of the 25-nm stuff. The performance numbers back up that assertion, with the 335 Series matching other drives based on the same SandForce controller silicon. The 335 Series may end up costing less than the competition, though; Intel has set the suggested retail price at an aggressive $184 for the 240GB drive, which works out to just 77 cents per gigabyte."

For speed, you just access more of them at once.

More like like ones with names that start with OC and end with Z) took the new flash chips and dropped them in to old designs with no account for the new behavior. The result, of course, was slower devices that were less reliable.

In general, the latency (speed, but other considerations also apply) benefit of SSD has to do with fetching the required data directly, instead of waiting for the head of the disk to move along the radius (seek-time), and for the disk to rotate to the correct location, or both. These issues dominate performance in a HDD, unless the files are big and contiguous, in which case transfer time gets more important and thus the benefit of SSD over HDD diminishes.

      Now, a RAID can have multiple disks working concurrently, so you will see a benefit only if your workflow involves reading a lot of files in parallel. Note that extra redundancy has additional penalties on writes, since consistency needs to be considered (and copies or parity blocks updated).
      So, in a sense, it all depends on the actual workload. Redundancy can actually make things slower.

      IMHO, the most interesting idea is a hybrid, that (with decent logic that may not be there) can choose which type of media is more useful given the concrete situation (read/write, big/small, etc). At least till SSD reaches a price point were no longer matters.

      Yes and no. If Windows crashes but the power stays on, the hard drive should still have an opportunity to write all the data still in its internal writeback cache, so the specific issue mentioned in the grandparent post does not come into play. However, any data in the operating system writeback cache is lost, potentially causing lost data for basically the same reason.

      Note that the internal hard drive cache issue the grandparent post is referencing is not specific to flash drives; it's an issue for virtually every consumer hard drive. Very few drives have battery back ups, and frankly, consumers don't really need them. Remember, the battery prevents data in the hard drive cache from being lost but does nothing for data in the OS cache (a UPS, on the other hand, can save the data in both caches).

      Really, data in the writeback caches is not _that_ important. The most important thing is that writes lost because of a crash don't leave the file system in an inconsistent state (potentially corrupting lots of data that you thought was saved safely to the disk). Modern journaled file systems provide this guarantee, so the usual worst-case scenario in a crash (because of a power failure or system crash) is that you lose any data saved in the few seconds leading up to the crash.

      A flash drive definitely needs a battery backup for its writeback cache if it plans to store data there for more than the usual amount of time (say, several minutes). I don't know if any consumer flash drives do that.

By taxing them you do not take away from their spending, that would make no sense for them, they will keep their spending at the same exact level as they need. You tax their investments. There is such a thing as 'economy of scale', so when you remove money from investments that are used by economies of scale, you reduce economic activity much more than if in fact you taxed somebody who is in a much lower bracket, where the productivity is much less efficient.

It is only marginally better than offensive wars, because while effort is wasted in either case, at least when people pick up trash there is less trash laying around. However neither of those activities (trash, wars, roads) improves the balance of trade.

    It does not matter how much trash is picked up. Unless your importers are happy to be paid in trash that you pick up, this trash (and the fact that it is picked up) only does one thing: it requires reduction in real economic activity (via taxes) and requires the money, that otherwise can be spent on real economic activity (productive activity) to be given to people who are at that point not part of the legitimate economy.

    Actually that is where there is the true multiplier effect (not the nonsense that the Keynesians like to talk about). The productive investments are reduced, to there is less economic activity. The people are moved into the public sector, so government grows and all the activities grow that depend on the taxes. The people are moved from the productive private sector into the public sector, so that there are fewer resources in the private sector, this may have an effect of raising prices in an inefficient manner. The people are paid money from the taxes and end up buying goods produced elsewhere, thus the trade imbalance grows bigger rather than getting smaller.

    Taking money from a company that, for example builds SSDs and spreading that money among 'the poor' does not increase productivity, it only steals from the SSD company. TWICE.

    First time it steals from the SSD company when the taxes are taken, the second time it steals from the SSD company when the money that the SSD company CREATED is used to buy their own products.

    Actually that's the reason why the Chinese are still not able to buy their own products, because their government does precisely that: it buys US dollars and to do it the gov't prints renminbi. The US dollars are then used to buy US treasuries (not so much anymore, but they are holding them and are still rolling them over). This is the money that China GIVES to USA. Of-course the Chinese products go to USA as well, so the Chinese people are not actually trading, they are accumulating IOUs from USA, they will never be able to cash them in.

    With the corporate and income taxes it's a similar situation: the money that the company makes (company creates money by creating wealth, money is just a convenient representation of wealth, without wealth money has no meaning, so without products created by companies, money has no meaning and no value, so the paper is not money) that money that company makes is taken away from the company by gov't by force (threat of violence).

    So the company has less money to invest (the people who have less money to invest, will still spend the same, but they will invest less), so company cannot increase its efficiencies as much. Then that same money comes back to the company washed through the gov't and people who did not work for that money.

    You think this INCREASES productivity? This STEALS productivity. Any time a person gets some money he didn't work for (in a free market, not gov't, all gov't workers are by definition on welfare even if they have to show up in gov't offices for their 'jobs'), that person uses that money to buy something that was made by a company that was taxed to give this person that money. Any time that happens there is a real multiplier effect of economic destruction.

    That person didn't have to work to earn the money, so he didn't add any wealth to the economy, but he is extracting the wealth to spend it, not to produce anything.

    Productivity is not in spending, it's not in consuming something, productivity is in producing, creating, manufacturing. Consumption is a trivial consequence of production, not the other way around, consumers do not produce, they are not building factories and products, they are not creating better SSDs or cheaper TVs or whatever. They will be lucky if a company creates an expensive one and the people who are wealthier buy those things (like the first expensive SSDs), so that eventually companies have enough investment to make more efficient production lines and better tech, so that the prices can come down and now the poorer people can get the product.

    And yes, actually 'wealth tax' would be less destructive than income tax, it's still a terrible tax, but at least it doesn't tax PRODUCTION, it taxes whatever is allocated for consumption. So an individual could AVOID a wealth tax on all of his investments, while he would probably be taxed on all of the money he allocates for his consumption.
