    Samsung's HHD prototype
    Samsung is preparing to release a new Flash memory-assisted computer hard drive that boasts improved performance, reduced energy consumption, a faster boot time, and better reliability. The new hybrid hard drive will be released around the same time as the upcoming Windows Vista operating system and will be one of the first hardware designed specifically to benefit from it.

    Samsung's HHD - faster boot and resume on Vista
    In mid-May 2006, Samsung unveiled a prototype hybrid hard drive (HHD) at WinHEC, the Windows Hardware Engineering Conference. Samsung's prototype HHDs have a buffer of 128 or 256 MB, much larger than the 8-16 MB of cache in current hard drives. This new buffer differs from the existing cache buffer on hard drives not only in size but also in structure, composition, and qualities. Conventional cache is made out of volatile memory that is erased when the drive is powered down. HHDs add another layer of cache consisting of Flash memory that is non-volatile and can be accessed quickly when the drive is powered on. Adding a large buffer to a hard drive can also reduce the drive's power consumption, thereby increasing the battery life, and reducing the time required for the system to resume its operation after suspension. Indeed, boot or resume time will occur about twice as fast as conventional hard disk drives, saving 8-25 seconds, and laptop batteries will provide 20 - 30 minutes more power. Another added bonus of the HHD is the improved reliability due to less mechanical wear and tear.

    Samsung and other manufacturers are currently pursuing Solid State Drive (SSD) technology (to be covered in an upcoming TFOT article). Currently Flash prices are too high to allow SSDs to replace standard hard drives of any reasonable size and, although Flash prices are continually falling, it will be several years until such a drive will become affordable to most users. Here enters the near-term solution for enjoying improved performance at a reasonable price - the hybrid hard drive, combining the low cost and large storage capacity of conventional hard drive technology with quick and low-power Flash memory.

    Apart from the reduction in Flash memory prices, hard drive manufacturers such as Samsung believe that we are about to undergo a major storage revolution in the next few years due to the upcoming release of Windows Vista. This new operating system from Microsoft will introduce three new performance-enhancing technologies: SuperFetch, ReadyBoost, and ReadyDrive. According to Microsoft, "SuperFetch understands which applications you use most, and preloads these applications into memory, so your system is more responsive". Windows ReadyBoost allows users to use a removable Flash memory device such as a USB thumb drive to improve system performance. ReadyBoost retrieves data stored on the Flash memory more quickly than data stored on the hard disk, decreasing the interval until the PC responds. Windows ReadyDrive enables Vista-based PCs equipped with an HHD to boot up faster, resume from hibernate in less time, preserve battery power, and improve hard disk reliability.

    Hard drive platters won't have to spin as much
    Hard disk platters are components of hard disk drives that consist of circular rigid disks that store magnetic data. While the platters in conventional hard drives rotate most of the time, thereby consuming a great deal of power, the platters in HHDs are usually at rest, as if they were off. In HHDs, incoming data is generally written to the Flash buffer and any saved documents are saved to the buffer, instead of being written to the hard drive each time. Only when the Flash buffer is almost full or when the user accesses a new file that is not stored on the buffer, will the HHD platter rotate or "spin up". Thus, the battery power of laptops with HHDs is preserved, extending battery life.

    Samsung's Hybrid Hard Drive Exposed
    Written by Iddo Genuth Thursday, 19 October 2006

    Samsung is preparing to release a new Flash memory-assisted computer hard drive that boasts improved performance, reduced energy consumption, a faster boot time, and better reliability. The new hybrid hard drive will be released around the same time as the upcoming Windows Vista operating system and will be one of the first hardware designed specifically to benefit from it.

    In mid-May 2006, Samsung unveiled a prototype hybrid hard drive (HHD) at WinHEC, the Windows Hardware Engineering Conference. Samsung's prototype HHDs have a buffer of 128 or 256 MB, much larger than the 8-16 MB of cache in current hard drives. This new buffer differs from the existing cache buffer on hard drives not only in size but also in structure, composition, and qualities. Conventional cache is made out of volatile memory that is erased when the drive is powered down. HHDs add another layer of cache consisting of Flash memory that is non-volatile and can be accessed quickly when the drive is powered on. Adding a large buffer to a hard drive can also reduce the drive's power consumption, thereby increasing the battery life, and reducing the time required for the system to resume its operation after suspension. Indeed, boot or resume time will occur about twice as fast as conventional hard disk drives, saving 8-25 seconds, and laptop batteries will provide 20 - 30 minutes more power. Another added bonus of the HHD is the improved reliability due to less mechanical wear and tear.

    Samsung and other manufacturers are currently pursuing Solid State Drive (SSD) technology (to be covered in an upcoming TFOT article). Currently Flash prices are too high to allow SSDs to replace standard hard drives of any reasonable size and, although Flash prices are continually falling, it will be several years until such a drive will become affordable to most users. Here enters the near-term solution for enjoying improved performance at a reasonable price - the hybrid hard drive, combining the low cost and large storage capacity of conventional hard drive technology with quick and low-power Flash memory.

    Apart from the reduction in Flash memory prices, hard drive manufacturers such as Samsung believe that we are about to undergo a major storage revolution in the next few years due to the upcoming release of Windows Vista. This new operating system from Microsoft will introduce three new performance-enhancing technologies: SuperFetch, ReadyBoost, and ReadyDrive. According to Microsoft, "SuperFetch understands which applications you use most, and preloads these applications into memory, so your system is more responsive". Windows ReadyBoost allows users to use a removable Flash memory device such as a USB thumb drive to improve system performance. ReadyBoost retrieves data stored on the Flash memory more quickly than data stored on the hard disk, decreasing the interval until the PC responds. Windows ReadyDrive enables Vista-based PCs equipped with an HHD to boot up faster, resume from hibernate in less time, preserve battery power, and improve hard disk reliability.

    Hard disk platters are components of hard disk drives that consist of circular rigid disks that store magnetic data. While the platters in conventional hard drives rotate most of the time, thereby consuming a great deal of power, the platters in HHDs are usually at rest, as if they were off. In HHDs, incoming data is generally written to the Flash buffer and any saved documents are saved to the buffer, instead of being written to the hard drive each time. Only when the Flash buffer is almost full or when the user accesses a new file that is not stored on the buffer, will the HHD platter rotate or "spin up". Thus, the battery power of laptops with HHDs is preserved, extending battery life.

    To learn more about Samsung's hybrid hard drive technology, TFOT interviewed Andy Yang, the Strategic Marketing Manager of Samsung's Memory Division.

I see this new feature operating in this way and in the spirit of the silly menu item reordering based on what application have been used recently.

      1/ Vista boots, starts a pile of services and asks for a login.

      2/ Vista looks up a list of recently used applications and preloads them into memory - I'm assuming it may be a few of them plus MS Office and IE. This takes time and may fill almost all available memory for a "power user" or a kid that just likes to draw pictures or play games.

      3/ After all this preloading the user gets their interactive shell and starts an application that is not normally used (time for disk access required) that requires more memory that is available. The OS is not stupid so it moves some stuff that it might not need yet but isn't sure to virtual memory - so the memory your preloaded applications are using gets written to a different part of the disk (which takes time). Bringing it back from virtual memory later will be easier and faster than the initial preload which is why I don't think what would normally be the obvious step of just releasing the memory will be taken as mentioned above - please correct me if I'm wrong.

      4/ At the end of the day for a typical MS window desktop computer the user turns their machine off (or just logs off), so a lot of files that were preloaded at startup for large applications will never be used until the user starts the machine up again. Some sort of hibernate will lessen this but it works by dumping even more stuff to disk and retrieving a lot of stuff form disk - but at least it will take less time than the initial preload.

      Now I don't like this because I currently manage to fix large numbers of MS Windows problems by feeding the machines more memory and/or disabling as much stuff at startup as possible. If you have a machine with a few GB of memory now you are using applications that can fill it, are running many applications that may not be used every session, and are running complex applications that take big chunks of resident memory before they ever do anything - so you would have to wait and you'll still go into swap with lots of memory. If you don't have a few GB of memory you can't afford to preload a lot of applications. In the middle with very few applications you will be OK - but you are running a machine with much more memory than you would normally need.

      When a user picks up the receiver, the exchange picks one of the available lines and routes the line to the user, so that (s)he may dial. In the event that there's no available lines, the user doesn't get a dial tone.

      Physical memory is the lines from the backbone into the local exchange. Each application however always "sees" all the memory as available, similar to how you don't worry about if you can dial when you pick up the receiver, you just expect it to be.

      The term "virtual memory" comes from the fact that the way the application accesses memory is not directly linked with the physical memory.

      The cpu and the OS then cooperates to "route" (map) the physical pages to the pages used by the application, so to speak.

      Due to the way this cooperation is done (at least on windows), it is possible for the OS to store some of the physical pages on a different medium, say a hard disk, which is usually called swapping. This is not a requirement for using virtual memory.

      So when a program tries to allocate more memory, and there are no free physical pages, the OS can copy a physical page to disk (swap it out), and then clear it and hand it to the program as if it was free all along. When the application who's page was swapped out wants to access that page, the OS get's notified and copies the page back into a free, possibly swapped out, page. The program is not aware that this process is going on, it's handled by the CPU and OS transparently.

      Now, here's the deal with the SuperFetch. Since the pages used by SuperFetch represents data that's already on disk, it's already swapped out so to speak. So when the OS needs a free page, all it has to do is to remove the page from its SuperFetch page table, clear it and serve it to the application.

      PS: That virtual memory analogy is probably flawed, read a real article if you want to get the full picture.

If the flash eventually fails then the pc will just get the data from the disk. Even if the flash fails over 4 or 5 years, the drive will still work, and it's still worth the premium IMO.

    Actually I think it's more like fixing software problems in Hardware. The situation in which this technology will improve access time is when you have to randomly seek on your harddrive. Unfortunately that is needed in Windows as there is little possibility to keep all your bootup files one after another in the order you need them. With Linux, however that is rather easily possible. You can create an initial ramdisk which the computer can load very quickly without much booting and then boot from it. Theoretically, if you have enough RAM, you can even load your complete system into it.

    So now you essentially have to spend a lot of money (Flash and Patents!) on a technology which will, at most, give you an decrease in boot-times and will be obsolete once the power management of the drivers support Suspend to Disk or Suspend to RAM. Just look at Linux or MacOS 8 on an old clamshell iBook. You just close it and it's "Off", you open it again, and after very few seconds it's completely back again.

    Flash has improved by leaps and bounds, with the earlier Flash drives supposedly lasting 1000 read/writes. Nowadays, from what I can gather the average Flash drive lasts 300,000 to 1,000,000 erase/writes. Good, but still finite and, relatively speaking, more finite then HDs. Flash also has cycling quality control problems, which are not as severe in the HD industry. All that said, I'm not saying Samsung shouldn't go ahead and make its hybird hard drive, but consumers should realize that the Flash component won't necessarily have the necessary longevity. This will proably be true with Samsung drives, because they're not likely to place small init files onto Flash but cache larger data (after all, what's the point of caching these small files if the performance improvement is going to be so low and just one time).

  40. Use Flash for directory structure not cache! by Anonymous Coward · · Score: 5, Interesting

    We did some basic research with Flash / HDD hybrids two years ago. As such disks weren't available, yet, we were using a real (Notebook)HDD and a IDE-Flash-HDD in parallel.
    Our goal was to minimize energy consumption for mobile devices (i.e. not a lot of ram available for caching and the device is switched off repeatedly to save energy).

    Using a very sensitive (time resolution wise) energy measurement device, we determined, that most energy was consumed by moving the heads into position. The difference was substancial: Around 0.63W for the HDD spinning idle and about 5.3W during heavy seeking (e.g. trigered by a "find ." in the root of a freshly booted system).

    We decided to not use the flash as cache (flash is quick to read, but slow to write) and just put the relatively static metadata (directory structure, inode tables...) onto the Flash drive, but keep there files and data on the HDD, as each directory access triggered a expensive seek, but delivered very few data, compared to reading a file.

    To simulate our mobile device we used a Linux-System limited to 32 ram to prevent the system from excessive caching.
    We observed up to a factor 8 reduced energy consumption and as a surprising side effect a factor 6 increase in speed!

    When increasing the available Ram, this advantage quickly vanished on repated benchmark runs, as the System appearently cached the directory structure very effectively. The first run after booting however still performed substancially better with our system, no matter the amout of ram. (And this was our target useage profile: Power on, search something, Power off).

    As the code was an embarrassingly ugly hack to the ext2 driver and we envisioned trouble keeping the hdd with the data and the flash-hdd in sync, it was not persued further.
    However with hybrid drives becoming available, it might be worth a more detailed analysis...

You rarely overwrite the data for a program's binary yet you read from it often. If you cache all of the program executables along with their config files (which also should be written to rarely), I'm sure you could see much faster performance or power savings because the only time you would need to spin up the hard drive is when you want to save new data (assuming your flash memory has enough storage to store most of the user's programs).

    If the Ubuntu/Debian people are rewriting init and not using launchd, they're seriously reinventing the wheel. The most often stated downside of launchd that I've ever heard is that it uses XML config files, rather than the flat text that's preferred by most people coming from a UNIX background, but I'm sure you could change that.

    The purpose of launchd, as I understand it, is that it keeps track of which processes can't start until other ones have started, and which can be started up in parallel. By parellizing the ones that can be run simultaneously, it shortens boot times substantially over the old sequential approach. The first version of OS X that used it was noticably speedier during boots than previous versions.
