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."

      It's pretty much all of the above. On the Intel side of things, making their own controllers just wasn't panning out. There are rumors that they had some problems with what was supposed to follow their existing in-house controller, but there's also a lot of evidence that the benefits of building their own controller wasn't worth the cost. The controller itself is very low margin, and Intel is looking for high-margin areas.

      Meanwhile SandForce has some extremely desirable technology. Data de-dupe and compression not only improve drive performance right now, but they're going to be critical in future drives as NAND cells shrink in size and the number of P/E cycles drops accordingly. Intel likely could have developed this in-house, but why do so? They can just buy the controller from SandForce at a sweet price, roll their own firmware (that's where all the real work happens anyhow), and sell the resulting SSD as they please.

      I actually asked a person who worked in Intel's storage research about this.

      It boiled down to this: Intel Research made the X25, and pushed it over to Intel's product teams who basically just put them in boxes and shipped it. And people loved it.

      Then Intel's product design teams tried to design a follow on controller and sucked entirely at it. So they got the research group to rev the x25 a few times, while they contracted with Marvell for controllers since they needed a SATA 6G controller for their own firmware.

      At that time, they hadn't switched to Sandforce, but judging by the fact that Sandforce has been quite dominant even back then, I wouldn't be surprised if Intel did almost no firmware customization now.

      I wouldn't have believed that Intel had sucked in SSD controller design had I not heard it from a Intel researcher (although they might have been biased given that the story make their peers look good) but looking back again, we're talking about the company that brought us Netburst and FBDIMMs.

      You'd need several dozen hard drives to even approach the IOPS of a single consumer level SSD. The SSD wins so many times over it's not funny.

      Now, if you're talking about sequential read/write speeds, that's a whole different matter. You'd need roughly 3-4 hard drives (in RAID 0 (no redundancy)... double that figure for RAID 10) to match the typical sequential read/write speeds of an SSD. At that point, the raw cost of the hard drives far exceeds that of the SSD, and that's ignoring the need for the extra SATA ports, cooling, physical space and the extra drive failures you need to deal with. So, the SSD wins again, hands down.

      Now, say you needed to store more than roughly 200 gigabytes of data and performance didn't matter at all, in that case, hard drive(s) will be more cost effective than SSDs.

    Umm.. No, that's not what trickle down economics is. Instead, what you've described is simply capitalism actually working -- in a quest to find more revenue a firm is providing supply to customers at lower prices by improving efficiency via R&D.

    Trickle-down economics (effectively -- but not exactly -- a pejorative term for supply-side economics) is the idea that a dollar given to those at the top of the socio-economic food chain will be redistributed down through the economy benefiting rather than being horded. It is used contrast against the "classic" or Keynesian view which is that the same dollar given to someone at the bottom will immediately be spent and will therefore work it's way across and up the socio-economic ladder benefiting all. A simple thought exercise which should make you question the validity of that idea:

    Give $10 to a bum on the street (or Rush Limbaugh):
          You -> Bum (Rush) -> Crack dealer -> Liquor store -> Liquor Distributor + Gun shop -> Liquor Distiller + UPS + Gun factory -> Farmer + Gas Station + Steel Factory -> ...

    Give $10 to Bill Gates:
          You -> Bill Gates -> Nothing

    That $10 did not impact Bill's participation in the economy one bit. Bill will buy what he was going to buy before he got the $10. Hell, he could have simply used it to light up a palette of Androids and iPhones to heat his chalet.

If they can use this investment in another product line, then that reduces the amount of the price of every CPU that has to go towards R&D.

    The other part of the problem, I would suspect, comes from some simulator results that Intel published about a decade ago. When they make a new CPU, they first run it in a complete simulation environment, where every aspect can be adjusted. They tried making the CPU infinitely fast in one experiment (i.e. every CPU cycle takes 0 simulation time) and found that this increased the overall performance by a factor of two. All it did was move the bottlenecks to memory and disks. Ensuring that fast disks are available helps stimulate the market for faster CPUs. We've seen recently in the FreeBSD kernel that the mantra for the last 20 years in a lot of places in the storage stack has been 'don't worry about optimising that - it's on a code path that does I/O, so the extra CPU time will be lost in the noise'.
