SuperSpeed SuperCache II and SuperVolume v1.0.16.0 Server

SuperCache 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. (For example: Dragon
Naturally Speaking v7.3 cannot be configured to
place its data on a different drive.)
3. Minimum risk of lost data.

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).

SuperCache can be used to cache an entire system
drive (e.g. drive C:) including the system pagefile.
SuperCache is the appropriate choice when a
particular program (e.g. database, game, etc.) needs
to access very large amounts data.

SuperVolume (previously known as SuperSpeed) is a
sophisticated yet elegant solution to the disk I/O
bottleneck. Employing a patented hybrid cache, it
mirrors an entire disk partition or volume in RAM.
In essence, a cache is created in RAM which
maintains a one-to-one relationship with its
associated partition or volume. All data residing in
the partition or volume is also present in the
cache. The file system, drive letter, and all other
attributes of the original partition or volume are
preserved.

How does SuperVolume accelerate a program? If a
program needs lots of data (e.g. images for a video
game) it's much faster to have it come from RAM than
from disk. When running a program with data on a
SuperVolume partition or volume, the disk-related
delays and `hiccups' normally experienced disappear!
The program is no longer hampered by slow disk
access, instead it can run smoothly at memory speed.

In addition, when a program needs to save
information it will first be saved to RAM. Then, in
the background, SuperVolume will save these changes
back to the physical disk for safekeeping. Therefore
the program's disk I/O problem is greatly reduced,
if not eliminated!

Write-through and write-deferred modes: SuperVolume
supports write-through and write-deferred modes. In
write-through mode, writes are immediately sent to
the cache and to the disk. This eliminates the
possibility of data loss in SuperVolume due to a
system crash or power failure. In write-deferred
mode, writes are immediately sent to the cache only,
and then to the disk at a later time. This mode of
operation results in read- and write-performance
similar to that of RamDisk. SuperSpeed Software
recommends enabling the write-deferred (or
lazy-write) feature ONLY on systems equipped with an
Uninterruptible Power Supply (UPS).

A key prerequisite for SuperVolume is to have, or
create, a hard drive partition that is small enough
to fit into available physical memory. For example,
a system with 1 GB of RAM typically has around 700
MB available for SuperVolume. Therefore, a 700 MB
disk partition or volume could be mirrored in RAM by
SuperVolume. Note: caution should be exercised to
leave sufficient memory free for the operating
system, programs and services.

In the explanation above we talk about putting data
(graphics, video, database etc.) on the SuperVolume
partition or volume. Why? Because this data is the
most frequently used. If there is enough RAM then
entire programs, like action games, can be installed
there and accelerated!

Creating the separate disk partition or volume
required by SuperVolume may require the use of
third-party disk partitioning software such as
