SuperSpeed
offers two high-performance RAM disk products: RamDisk
and RamDisk Plus® (compare).
These products create virtual disks from the server's system memory
(RAM). Although in many respects a virtual disk behaves like a
physical hard disk, in one key area it does not: it is much, much
faster, up to 50x faster or more. Like a physical disk, a RAM
disk can be assigned a drive letter and contain a file system
(including NTFS with compression). Applications can copy, move
and delete files on it. It can be shared, so other computers can
access it on a network. Additionaly, it can be mount point to
ease integration into application file paths.
RamDisk supports a single RAM disk with no backup
capability. RamDisk Plus adds multiple disk support,
system page file support, and a versatile disk image backup facility.
Its patented technology adds the ability to manually save the RAM disk’s
contents, or automatically save the contents when the server is shutdown.
This feature ensures that service and application data stored on the
RAM disk can be preserved between system restarts. During the subsequent
system start-up, the disk's image is automatically loaded.
Extended memory access
RamDisk Plus 11 has a most unique
feature. Our patent pending technology can access memory beyond the
limitation imposed by a Windows 32-bit operating system!
In other words, RamDisk Plus 11 can use "unmanaged" Windows'
memory e.g. above 4GB. It can also use the stubbornly inaccessable memory
between 3.2GB and 4GB.
This feature is now available in the 64-bit RamDisk Plus starting with
version 11.7.917. Any memory not managed by a Windows 64-bit
OS can now be included for use by a RamDisk! For example, Windows 2008
R2 Standard Edition 64-bit will manage up to a maximum 32GB of RAM.
If your system has more, then RamDisk Plus can make the extra "unmanaged"
RAM above 32GB available for a RamDisk!
See the product's help file for detailed explanation of what "unmanaged"
memory is and how to access and use it with RamDisk Plus 11.
On Windows server clusters RamDisk11 and RamDisk Plus 11 provide
support for a RAM Disk cluster resource. Cluster applications which access
temporary data on disk can now redirect their temporary data files to
a RAM Disk cluster resource to improve application performance. SQL
Server is an example of a cluster application that benefits from this
feature.
Risk
If the system loses power or crashes, the RAM disk's current
contents will be lost. An Uninterruptible Power Supply (UPS) can reduce
the risk of data loss but not eliminate it. For low-risk performance solutions,
see SuperVolume and SuperCache.
Security
Another reason for using a RAM disk is security or privacy.
Once the server is restarted or shutdown, the contents of the RAM disk
are lost. For some services or applications, this is an important attribute
that contributes to the protection of sensitive data or information.
Quality
"Designed for Windows Server 2003"
and "Certified for Windows Server 2008":RamDisk
and RamDisk Plus have been thoroughly tested to meet
Microsoft standards for Windows compatibility. Microsoft awards this
logo to products that deliver a reliable, high-quality computing experience
with Windows operating systems.

Other considerations
•
16 MB free disk space for installation
•
To support backup functionality, RamDisk Plus
requires sufficient free disk space to store the image file of each
RAM disk. The actual size needed will vary from less than a megabyte
up to the size of the RAM Disk.
