Intel, Micron Boost Flash Memory Speed by Five Times

Posted by ScuttleMonkey on from the fastest-draw-in-the-valley dept.

Lucas123 writes "IM Flash Technologies, a joint venture between Intel and Micron, announced they've been able to improve NAND memory and its circuitry in order to boost read/write speeds by five times their current ability. The new 8Gbit single-level cell, high-speed NAND chip will offer 200MB/sec read speeds and write speeds of up to 100MB/sec, which means faster data transfer between devices like solid-state drives and video cards. IM Flash Technologies plans to begin shipping the new chip later this year."

      Not really.

      There's still cycle time limits. The main issue came from NOR flash, which is different from NAND. NOR flash came first (mid-80s), and the very early versions suffered from poor lifetimes (~10,000 write-erase cycles). (However, they're perfect for firmware, which is their initial purpose - even during development, it's rare to wear it out). Modern NOR flash has a cycle life of around 100,000 cycles.

      In the early 90s, NAND flash came out, and due to their exploitation of quantum mechanics (NOR flash uses tunnelling and hot-electon injection (literally forcing electrons through the insulator). NAND flash uses tunnelling exclusively) resulted in a significant improvement in life - normally 1,000,000 cycles.

      Add in wear levelling, and things get interesting. Assuming a perfect wear-levelling algorithm, and maybe a large-block NAND chip (128kB block size), a 128MB chip (tiny these days) has 1,024 blocks. To wear it out, requires over a billion write-erase cycles! A GB chip would have 8192 blocks, thus over 8 billion write-erase cycles. And you want 32GB/64GB SSDs? It's gotten to the point where an SSD in normal use will probably outlast a mechanical disk.

      Oh, and most flash chips, these cycle times are very conservative - most will survive another order of magnitude of erase-write cycles before becoming unusuable.

      That's a USB issue, not a flash issue.

      The reason is that USB does things in transactions, and has to schedule all the transactions with priority. This is because of USB's fundamental flaw - it requires the host to poll devices. So a host will poll interrupt devices first, then handle isochronous transfers (bandwidth and time dependent traffic). Leftover bandwidth is then allocated to control and then bulk traffic. A USB host can do this once every millisecond, but most OSes break it out into more coarse granularity to avoid overloading the CPU when doing USB transfers. 10ms is about average for Windows, Linux is around 4ms. Basically, Windows will schedule all traffic on 10ms boundaries, so every part of a transaction will take place every 10ms. (10ms is a nice number because it means Windows can do the scheduling every timer tick).

      If you do a USB disk request (read block N), the USB Mass storage driver will make a transaction to read a block. It will then issue the request to Windows' USB stack, which then add it with all the requests. If there's sufficient bandwidth in the next 10ms frame, it'll add the request to that frame. In the meantime, it's handling the current frame. When the next frame goes through, it sends the request, and if your USB stick is fast enough (usually is, but hard disks, it isn't) it responds immediately. If your USB stick isn't fast enough, then it will accept the request and wait for Windows to poll it again to see if there's any data, at which point the data will be transferred.

      Funny I can't find the GT product listed on Corsair's website!

      Unfortunately I don't know any "brick and mortar" stores in my area that sell it either :(. I guess everyone else doesn't care about write speed.

  15. CacheFS by benow · · Score: 1
    Slightly off topic, but does anyone know the status of cachefs within the kernel? CacheFS was designed as a transparent generic cache for network files systems... nfs, etc. A read would pull into the cache and subsequent reads would come from cache.. so, a cache. It was designed for network filesystems, but I'm thinking it might apply to local file systems also. Specifically the cache could sit on a ram or flash based drive and pull off local hd's. As such, the commonly used bits (libs, etc) would reside on the cache and no longer be subject to seek and rotational latency... ie it'd be f*cking fast. Keeping the cache or profiling the cache across boots would lead to very fast loading (ie near instant) while still using slower, cheaper backend storage mechanisms. I was all set to try it out, but the most recent kernels are missing the cachefs documentation, leading me to think that cachefs is no longer supported in the kernel. Does anyone know the status of cachefs and if it is supported by recent kernels?

    Yes, I know fast, big ssds are coming and they'll be getting faster, but they'll be expensive for a while, but still slower than an iRAM and much slower than memory on a pcie16x slot, should such a thing ever happen.

    Fucking Finally. Thank God.

    SSD's have been the most overhyped and overpriced pieces of shit since day one. We can't go a few weeks without some magazine/online publication spewing the propaganda to people, and especially gamers, that SSD's are the Holy Grail of performance.

    I felt like coming downstairs on Christmas day to see my parents brutally butchered, the dog raped, and my presents smashed right before the jerk leans down and tells me that there is no Santa Claus... and he killed the Tooth Fairy and shoved her up the Easter Bunny's ass.

    The read speeds were great, but the write speeds were horrible. I could post quite a bit of independent tests showing the SSD's had serious problems when used in a RAID configuration and that due to the write speeds, were not actually a good solution to increase OS performance and responsiveness.

    1st Gen SSD is a total ripoff, but I can't wait for this to be applied to the next generation of SSD's. Don't let me down this time guys! Please.

      That's pretty disturbing for a response to an article about silicon. Got issues?

      It was not in response to the article exactly :)

      I was just expressing how deeply I was disappointed when SSD drives did not live up to their hype. You can search for whatever benchmark test you want to use, but the accepted value I am working with is an average of 8x slower write speeds.

      That's significant. Unless the write speeds improve, which the technology in the article can go a long way to doing so, SSDs are just not practical for most situations. Even less affordable when you are not getting that perceived performance gain for the money either.

      P.S - I got plenty of issues. Even spare ones. Need Any :)
