    In an hour it's written 114 mb to the drive.

    Assuming that's normal activity that's 2.6 gigs a day.

    Is that normal or is that high?
    That's pretty high. I bought and installed my 850 Pro on the 22nd of September and only have 0.75TB, and it's only that high because I have created and deleted a few VM's since I cloned to it. Oh yeah, and one re-image because of a theme gone south.

    Rapid White Paper:
    Samsung Solid State Drive
    RAPID mode
    White Paper
    © 2013 Samsung Electronics Co.
    Improving System Responsiveness with Samsung
    RAPID mode
    Innovative solution pairs advanced SSD technology
    with cutting-edge storage management techniques.
    At the 2013 Samsung SSD Global Summit on July 18th,
    Samsung introduced a powerful performance enhancement
    tool called RAPID (Real-time Accelerated Processing of I/O
    Data) Mode. Designed to increase the overall performance
    of PCs, RAPID mode analyzes the user’s application and data
    usage, optimizes all storage-related I/O for Samsung SSDs and
    eliminates system performance bottlenecks.
    In order to deliver the fastest and the most reliable user
    experience, RAPID mode focuses on improving random I/O
    performance with small size data at low queue depth. When
    frequently used data (hot data) is recognized, RAPID mode
    can also enhance the sequential performance.
    What is RAPID mode?
    RAPID mode is paired exclusively with Samsung 840 EVO SSDs and available as a feature of the accompanying Samsung
    SSD Magician Software Toolset (version 4.2 and later).
    When enabled, RAPID mode is inserted as a filter driver in the Windows storage stack. The driver actively monitors all
    storage-related activity between and among the operating system, user applications and the SSD. The RAPID technology
    analyzes system traffic and leverages spare system resources (DRAM and CPU) to deliver read acceleration through
    intelligent caching of hot data and write optimization through tight coordination with the SSD.
    Read Acceleration for Fast Access to Active Data
    Wouldn’t it be wonderful if your computer could “learn” your computer habits,
    such that it can actually improve your user experience? For example, if your
    PC could magically learn that you launch Outlook every morning and browse
    to your home page(s), it would make your e-mail database instantly available
    and make the home page(s) load faster.
    This is possible with the read acceleration technology in RAPID mode, which
    leverages spare system DRAM and CPU resources to manage a cache of “hot
    data”. System performance is improved when this hot data is automatically
    stored in memory such that future requests for that data can be served
    directly from DRAM, rather than going to the storage device. This improves
    the latency and throughput for the most active data, and directly improves
    daily user experience.
    RAPID mode behaves as an extension of the OS cache, which takes a rather
    simple approach to caching the most recently accessed data, while RAPID
    mode handles not only newer data, but also takes into account access
    frequency, file types, system status, RAM availability, etc.
    In order to further improve cache efficiency, RAPID mode may exclude
    certain data from the cache based on a variety of factors. This prevents
    unnecessary data from polluting the cache and allows us to keep the
    memory footprint to a minimum. For example, files that are meaningless to cache (like large media files) are automatically
    dismissed. Finally, the hot data is cumulative and persistent across multiple sessions and reboots such that if you have
    been working on a specific files or applications, you will be able to access that data faster as well. Your Microsoft Outlook
    email database, for example, would be a prime target for cache acceleration.
    Key Benefits
    Highest Performance.
    RAPID operates at the block and file system
    level to analyze application and data usage and
    eliminates system performance bottlenecks by
    dynamically leveraging system DRAM as a read/
    write cache.
    Easy Installation, Fully Automated.
    The software is fully automated, installed via
    Samsung SSD Magician; no user management is
    necessary.

    Write Optimization to Maintain Consistently High Performance
    A persistent performance bottleneck in PCs is due to the many background tasks undertaken by the operating system,
    like updating logs or indexing. Failure to complete these frequent, small random transactions in a timely manner is what
    causes the stuttering you may have encountered with your PC. Recognizing that SSDs (including the 840 EVO SSD) favor
    transactions that can be processed in parallel, RAPID mode specifically identifies low-queue-depth random write requests
    and combines them into larger packets of data that can be processed at higher queue depths and written more like large
    transfers across many NAND die. This dramatically improves the completion time for those small transactions, virtually
    eliminating any storage-related stuttering in your system.
    The following chart demonstrates the effectiveness of this approach -
    How do I enable RAPID mode?
    1. Connect SAMSUNG SSD 840 EVO to your PC
    2. Install Magician v4.2
    - RAPID mode is available as an Advanced Feature in Magician 4.2.
    3. Enable RAPID mode
    - Click “RAPID mode” tab
    - Check the Minimum Requirements, Select Target drive and Click “Enable”.
    - Click “OK” for system reboot.
    - RAPID is enabled.
    Are there any risks with using RAPID mode?
    RAPID was specifically designed to not add any additional risk to user or system
    data, even in the event of a power-loss. In fact, RAPID strictly adheres to Windows
    conventions in its treatment of any buffered writes in DRAM -- RAPID obeys all
    “flush” commands, so any writes buffered by RAPID will make it to the persistent
    media just like the Windows OS cache or the HDD cache. (Consequently, the data
    loss risk is identical to that of Windows OS cache or HDD cache).

    Furthermore, RAPID mode is mindful of any changes in system behavior or
    resource availability, meaning that RAPID will scale back or release (and re-acquire)
    system resources seamlessly based on system activity and requirements. RAPID
    consumes at most 25% of the installed DRAM, up to a maximum of 1GB, but will
    scale down resource usage and eventually revert to a pass-through mode if the
    CPU core(s) or DRAM is occupied with other system tasks. (This technology is really
    designed to make use of excess system resources).

    Closing Thoughts
    Samsung believes that the 840 EVO SSD and RAPID mode combination represents a compelling mix of killer technology
    and a creative and efficient use of spare system resources to deliver an optimal and seamless end-user experience. As
    the SSD industry continues to evolve, Samsung will continue to be on the cutting edge, and Samsung’s RAPID mode is
    just one of the many ways we intend to deliver on our view that the evolution of storage will require not just device side
    technology advancements, but also host-side software innovation.
    The software story around
    Samsung’s SSD 840 EVO
    is quite possibly the
    strongest we’ve ever seen
    from an SSD manufacturer.
    Samsung’s SSD Magician
    got a major update not too
    long ago, giving it a
    downright awesome UI.

    Question Answer
    1) What is RAPID mode?
    RAPID mode from Samsung increases the overall performance of your computer by pairing the industry’s most
    advanced SSD with cutting-edge storage management techniques to deliver the fastest and most reliable user
    experience.
    RAPID mode is installed as a filter driver in the Windows storage stack. The RAPID mode technology analyzes
    system traffic to the Samsung SSD and leverages excess system resources (unused DRAM, CPU cycles) to deliver
    optimized write I/Os to the SSD and caching hot data for improved responsiveness based on frequency, recency,
    file type, etc.

    RAPID mode is available as a part of the Samsung SSD Magician Software Toolset.
    2) What are the key features of
    RAPID?
    Read/Write Cache. RAPID mode uses system DRAM as a cache of “hot data” based on frequency, recency, file
    type, etc, such that subsequent requests can be served directly from DRAM, rather than going to the SSD.
    Write Optimization. System write requests are processed for optimized performance with Samsung EVO SSD.
    File Awareness. RAPID mode may exclude certain files from caching based on a variety of factors, including file
    type, file size, etc. This prevents unnecessary data from polluting the cache.
    Persistent Cache. RAPID mode maintains cache map across system reboot to maintain consistent high-
    performance operation.

    Cache Compression. RAPID mode dynamically compresses and de-compresses cache contents to dramatically
    improve cache efficiency. Optimized for Samsung EVO. RAPID Mode was co-developed and optimized for the
    Samsung MEX controller.
    3) What are the key benefits of
    RAPID mode?
    Highest Performance. RAPID mode operates at the block and filesystem level to analyze application and data
    usage and eliminate system performance bottlenecks by dynamically leveraging system DRAM as a read/write
    cache.
    Easy Installation, Fully Automated. The software is fully automated, installed via Samsung SSD Magician;
    no user management is necessary.
    4) What happens when my
    applications require more
    memory?
    RAPID mode will release and re-acquire system resources seamlessly based on system activity and requirements.
    RAPID mode consumes at most 25% of the installed DRAM, up to a maximum of 1GB.
    5) Does RAPID mode keep its
    improvement across system
    reboot?
    RAPID mode maintains its cache across reboots.
    NOTE: RAPID mode was not designed to improve boot performance. In fact, RAPID mode does not go into effect
    until the system is quiescent (about 60 seconds). This is because the system and/or user may try to launch some
    applications at boot up so the system may already be under stress, so we intentionally delay RAPID activity to avoid
    interference with the user’s boot sequence.
    6) How does EVO compare with and
    without RAPID?
    Samsung EVO is the industry’s highest performing SSD solution across all dimensions of measure (sequential/
    random read/write, longevity, cost, etc). RAPID mode extends Samsung’s advantages by leveraging spare system
    resources to provide even more performance, especially for random requests with low queue depths and smaller
    data sizes.
    7) Why did Samsung develop
    RAPID mode?
    Samsung believes that future advancements in storage technology will come from both device-side inventions
    as well as host-side software innovation. RAPID mode is the first step in a family of new technologies under
    development and investigation from the team at Samsung.
    8) What user scenarios are most
    improved with RAPID mode?
    RAPID mode will provide performance improvements across the board. Most noticeable will be small random write
    performance, access to frequently-used data, and overall system responsiveness.
    NOTE: although some sequential accesses are accelerated by RAPID mode, the technology is not intended to
    accelerate large sustained reads/writes.
    9) Is RAPID mode used to mask
    Samsung EVO problems?
    Absolutely not. Samsung EVO is the most advanced SSD on the market. RAPID mode simply augments the already
    excellent performance of EVO by leveraging spare system resources to further accelerate the storage interface.
    10) What are the system
    requirements to use RAPID mode?
    RAPID mode requires the following –
    1) Window7 or Window 8 (32- or 64-bit)
    2) 2GB DRAM (minimum)
    3) Samsung 840 EVO SSD

    SAMSUNG CONFIDENTIAL Author: David Lin (david.lin@samsung.com)
    Question Answer
    11) Why not let advanced users
    allocate more than 1GB of RAM to
    RAPID mode?
    This is a fairly conservative setting, in order to provide a nice performance boost with minimal cost, to a broad range
    of users. Obviously, if RAPID mode allocated a larger amount of memory, we would be able to provide even more
    acceleration and sustained performance across larger workloads, but we decided to stick to a max of 1GB as our
    initial setting until we have further characterized performance across more systems and users. We are keeping our
    eyes/ears open for your feedback, so could potentially change this setting in a future release, if it looks like we are
    being too conservative.
    12) Can RAPID mode be used with
    other SSD?
    Currently, RAPID mode is only supported with and optimized for Samsung 840 EVO SSD. Future versions of RAPID
    mode will be backwards compatible with selected Samsung SSDs, including 840 Pro.
    13) What is the difference between
    the 1GB cache on-board with the
    SSD and the cache in RAPID mode?
    The onboard LPDDR RAM cache is used by the SSD controller for block management and wear-leveling purposes
    and SSD mapping table.
    14) What is the difference between
    the 3GB (or more) TurboWrite cache
    and the RAPID mode cache?
    RAPID mode and TurboWrite work hand-in-hand to optimize write performance for the SSD. Since RAPID mode
    operates at the block and filesystem level, it can provide awareness of how the data should be stored and retrieved.
    RAPID mode then coalesces and optimizes write I/O at the host for TurboWrite. TurboWrite acts as a large SLC
    buffer for incoming writes. In the background, TurboWrite will transfer user data from the buffer to primary storage.
    15) What are the typical
    performance results with RAPID
    mode?
    Since RAPID mode utilizes spare CPU cycles and DRAM capacity, together with Samsung 840 EVO SSD, to deliver
    improved system level performance, measured performance (via benchmarks, user scenarios) will vary depending
    on all the above factors.
    For our benchmark system, with Z77 platform, Core i7 CPU, 8GB DRAM, and 240GB 840 EVO SSD attached and
    accelerated by RAPID as a secondary drive has shown the following performance results in Crystal Disk Mark
    (no other applications running) –
    Seq RD = 774 MB/s, WR = 1133 MB/s, 512K RD = 1102 MB/s, WR = 971.4 MB/s 4KQD1 RD = 106.8 MB/s,
    WR = 445.0 MB/s 4KQD32 RD = 484.2 MB/s, WR = 447.2 MB/s
    16) What does RAPID mode write
    optimization entail?
    RAPID write-optimization consists of a number of features to improve write (and subsequent read) performance.
    One of the features we described was our ability to maintain higher queue depths.
    17) When writes are flushed from
    the RAPID mode cache, are they
    treated as a normal writes and
    funnelled through TurboWrite, or
    do they go directly to the TLC?
    Writes flushed from RAPID are treated as normal writes; they go directly to the TurboWrite buffer.
    18) Is there any risk to using
    RAPID mode?
    RAPID was specifically designed to not add any additional risk to user or system data, even in the event of a power-
    loss. In fact, RAPID strictly adheres to Windows conventions in its treatment of any buffered writes in DRAM --
    RAPID obeys all “flush” commands, so any writes buffered by RAPID will make it to the persistent media just like the
    Windows OS cache or the HDD cache. (Consequently, the data loss risk is identical to that of Windows OS cache or
    HDD cache)
    19) How does RAPID mode
    compare to Ramdisk?
    A Ramdisk is a solution which creates a temporary storage device using a fixed amount of system DRAM. Ramdisk
    will often compete with other applications for DRAM. The Ramdisk contents are lost after a power-loss. Ramdisk
    content needs to be actively managed by the user (copy, delete, rebuild). Eventually, all data needs to be written to
    the SSD for data integrity reasons.
    20) How does RAPID mode
    compare to SuperFetch?
    Superfetch is an important Windows feature which preloads certain frequently used applications into DRAM to
    improve initial program launch. RAPID is different in that it caches both application files as well as frequently used
    user data. RAPID also caches both read and write I/O.
    21) How does RAPID mode
    compare to Windows DRAM cache?
    Windows DRAM cache will store recently used data in the DRAM cache in anticipation of quick reuse by the user. For
    example, if a user opens a document, then wants to reopen the document again shortly later. The DRAM cache is
    only active per-session, so it is not retained across reboots like RAPID mode is.

    Only my Documents, Downloads, Music, Pictures, Video and Theming Stuff libraries are move to a 2nd internal HDD, basically stuff that just takes up space and/or gets moved around, and is safe if my C: disk (SSD) goes teats-up. But my user folder is still on my SSD because it's faster for the software to access.
