SuperCache Express™ breaks
the disk I/O bottleneck by using the computer's RAM to hold or contain
the most frequently used disk data. This 'container' is referred to as
a cache. With SuperCache, as a program sends and receives disk data, the
most frequently used data is read from and written to RAM – not
the hard drive – thus accelerating the program's performance. SuperCache
implements our patented block-level cache technology
to increase performance above that of the operating system’s file-level
cache.
SuperCache is an excellent choice for these scenarios:
The data files are located on a disk partition or
disk volume that is too large to fit into available
physical memory, and cannot be moved to one where they will
fit.
3.
Minimum risk of lost data.
Unlike our RamDisk products not all the data
will be available in RAM all the time. Some will come from the hard drive.
Nonetheless, depending upon the size of the cache and the nature of the
disk I/O demands, performance accelerations can be significant and often
dramatic.
SuperCache is not recommended for a boot volume (usually C:) . Use only on non-boot data volumes.
Deferred-write mode
By enabling its lazy-write mechanism, SuperCache can
also accelerate writing data to disk. This mechanism delays writes to
the hard drive. This can 'smooth out' I/O activity on the hard drive.
It is important to note that enabling lazy-write increases the risk
of data loss in the event of a system crash or power failure. SuperSpeed
Software recommends that enabling the lazy-write feature ONLY on systems
equipped with an Uninterruptible Power Supply (UPS).
Support for NUMA
Starting with Windows XP x64 through Wndows 7 x64 provides special
support for machines with a non-uniform memory architecture (NUMA).
When active on such platforms, the memory manager for SuperCache
Express examines the processor and memory affinities reported
by Windows and the ACPI SRAT, and then optimizes physical memory allocations
across the described NUMA nodes. The NUMA support in SuperCache
greatly improves the speed of memory allocations and equalizes
the distribution of cache allocations among the NUMA nodes. Currently,
NUMA support does not include the ability to build caches on specific
nodes.
New Interface
SuperCache Express now has a more user friendly and
informative interface.

Added Feature called "Mirror
Mode"
SuperCache Mirror Mode (formerly a separate product called SuperVolume)
allows the user to duplicate an entire volume/partition into
RAM. Learn

Quick start instructions:
There are two ways to configure SuperCache Express (SCE) either from
Graphical User Interface(GUI) or via the Command Line Interface(CLI).
To configure or modify caching from the GUI
1) Double click the desktop icon.
2) Select a volume
3) Select either the first menubar icon OR Action -> Cache
- OR -
To access SCE from the CLI
1) Open a Command Prompt with Administrative privileges
2) Type "vfcfg -help" will provide an overview of the command
line syntax.
Maximum: as per the amount recognized by Microsoft Windows™.
(see table above)
•
Types: all including SDRAM, DDR, DDR2, DDR3, Rambus etc.
•
Supports use of "Unmanaged Memory (UM)" for 32-bit
Windows operating systems. UM allows SuperCache 5 to access memory
above the 4 GB OS limit. (see table above)
Other considerations:
•
Caching a boot volume (typically C:) is not recommend.
