Superspeed offers two high-performance RAM disk products:
RamDisk and RamDisk Plus.
RamDisk and RamDisk
Plus®
Both use our patent-pending memory management
(up to 512 GB) to create a virtual disk out of RAM. The RAM disk
appears like a physical hard disk to the operating system and
programs. You choose its size (depending on the amount of RAM
in your system), drive letter, and file system. You can copy,
move and delete files on it. Like a physical disk, a RAM disk
can also be shared so as to be accessed by other computers on
a network.
The most important difference between a RAM disk and a hard disk is
access speed. The time taken for a hard disk to move its magnetic heads
over the spinning disks (much like the arm moving over old vinyl record
player) is typically measured in milliseconds (thousandths of a second).
Whereas a RAM disk does not have mechanical parts and its access speed
is typically measured in nanoseconds (billionths of a second). Access
to a RAM disk may be 50 times faster or more than to a hard drive.
RamDisk supports a single RAM disk with no backup capability.
RamDisk Plus Features:
RamDisk Plus adds multiple disk support, system
page file support, and a versatile disk image backup and restore facility.
You can manually save the RAM disk’s contents to an image file,
or have the contents saved automatically when the computer 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. A "live"
RAM disk image may be backed up even with open handles to the volume.
A RAM disk viewer lets you load image files as read-only devices.
Extended memory access
RamDisk Plus 9 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 9 can use "unmanaged" Windows' memory e.g. above 4GB. It can also use the stubbornly inaccessable memory between 3.2GB and 4GB.
See the product's help file for detailed explanation of what "unmanaged" memory is and how to access and use it with RamDisk Plus 9.
Virtual
and removable disk types are also supported. Disks can be created with partition
tables or without. RamDisk 9.0 and RamDisk Plus 9.0 can create partitionable
RAM disks, which are supported by Volume Managment software. Windows'
MMC disk managment snap-in recognizes and manages partitionable RAM
disks. They are also compatible with other software such as Partition
Magic and Veritas Volume Manager. RamDisk Plus 9.0 also can create and
configure non-partitionable RAM disks, which are compatible with RAM
disks created by RamDisk and RamDisk Plus version 8.0. RAM disks can
be zeroed out upon removal and the disk image file can be preserved
upon removal. A new licensing mechanism binds the software to the machine
name rather than a system ID.
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
(when the auto-save feature is disabled). For some services or applications,
this is an important attribute that contributes to the protection of sensitive
data or information.
"Designed for Windows Vista & XP "
RamDisk and RamDisk Plus have been
thoroughly tested to meet Microsoft standards for Windows Vista and XP compatibility.
Microsoft awards these logos to products that deliver a reliable, high-quality
computing experience with Windows operating systems.
For disk I/O performance benefits similar to RamDisk but with low or
no added risk of data loss, see SuperVolume
and SuperCache II.

Memory Support
•
Minimum: 512 MB RAM
•
Recommended: 1 GB or greater
•
Maximum:
•
Types: all including SDRAM, DDR, DDR2, Rambus etc.
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.
SuperSpeed LLC is the owner of the following U.S. Patents 5577226, 5606681, 5918244,
6370615, 6629201, 6651136, 7017013, 7039767, 7111129, and other patents
are pending.
