SuperCache Express™ 6 for Desktop Systems

  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:
1. The data files are larger than available physical memory.
2. 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.

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 10 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.

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.
