Hibernation Mode; Virtual Memory - Samsung 840 White Paper

the fastest possible performance. Features like "Hibernation Mode," "Virtual Memory," and "indexing," which require
extra writes to the SSD in order to function, are enabled for added speed.
The "Maximum Capacity" profile disables features that require a large amount of extra storage space to function,
including "Hibernation Mode," "Virtual Memory," and "Automatic Backup," all of which reserve rather large portions of
SSD storage. This configuration is particularly useful for those who purchased a low capacity SSD and want to ensure
they have as much space available as possible for their own files without the OS claiming precious space for itself.
"The Maximum Reliability" configuration profile disables all features that produce extra writes to the SSD in order to
maximize potential SSD lifespan. It is a well-known fact that SSDs have a limited number of write/erase cycles. While this
limit is far beyond any usage level a regular user might encounter, some still prefer to take extra cautionary measures.
Features like "Indexing," "Hibernation Mode, "Virtual Memory" and "Automatic Backup," which make frequent writes to
the SSD, will all be switched off.
While there may be a slight performance decrease when using the "Maximum Capacity" or "Maximum Reliability"
profiles, especially when waking from sleep, SSD technology's incredible read/write speeds ensure users will still enjoy a
noticeable performance and usability improvement over traditional hard disk drive (HDD) technology.
Of course, there is always the option to choose a custom configuration via the "Advanced" tab. Even power users will
find this tab useful, as it provides quick access to all relevant OS features either via simple toggle or via a shortcut to the
appropriate Windows dialog box.
Explanation of OS Settings

Hibernation Mode

Hibernation Mode enables quick restart times (particularly important for Laptop PCs) by saving the current system
status to the hiberfil.sys file (hidden) when the PC power is turned off. Windows 7 or later will automatically reserve up
to 75% of the available system memory (DRAM) for the hyberfil.sys file, even if the entire reserved capacity may not be
fully utilized. When the system goes into hibernation, the contents in DRAM are copied to NAND flash. Because this
produces extra writes and may require a significant amount of storage space to function, this feature is turned OFF for
"Maximum Capacity" and "Maximum Reliabilty" modes. Laptop or Desktop users who frequently leave their machine for
a period of time but demand a quick resume time may wish to enable this feature via the "Advanced" tab in Magician,
especially if they have a larger SSD.

Virtual Memory

In order to address any potential lack of memory capacity, the Windows OS automatically generates a block of virtual
memory (stored in a hidden pagefile.sys file) on the "C:" drive. In the past, before PC Memory (DRAM) was available
in high volume, PCs needed to utilize some HDD space to address any memory shortcomings. The Windows OS
automatically reserves storage space for Virtual Memory equal to 100% of physical DRAM capacity (e.g. Windows will
reserve 4GB of Virtual Memory for a system with 4GB of DRAM or 32GB of capacity for systems using a 64-bit OS and
featuring 32GB of DRAM). Reserved space will be dynamically allocated based on resource needs, which often never
exceed the available physical memory (DRAM) in recent PCs that feature 4GB of memory or more. Thus, it is possible
to reduce or even eliminate the use of virtual memory (with the additional fringe benefit of improving overall system
performance and reliability).
The "Maximum Performance" conifguration profile uses Window's default Virtual Memory settings. Magician sets a
minimum of 100MB and a maximum of 1GB of Virtual Memory for the "Maximum Capacity" and "Maximum Reliability"
profiles. A minimum amount of Virtual Memory capacity is necessary because some software applications require
at least a small amount of Virtual Memory, which is why Magician sets 100MB rather than elminating it altogether.
Additionally, systems running for extended periods (days or weeks at a time) without a restart may run out of Virtual
Memory if the capacity is set too low, so Magician sets a maximum of 1GB of Virtual Memory to accommodate this
scenario. If your particular system needs require more Virtual Memory, you may adjust settings manually via the
"Advanced" tab in Magician.
Indexing Service/Search
Windows automatically indexes the content of data files in order to perform very fast Keyword searches. Users who
