A RAM disk can be restored to contain certain data even following a power down and power up cycle of a volatile RAM device. This is referred to herein as a “persistent” RAM disk to indicate that the otherwise lost data is restored on restart of the computer, and therefore appears to the user to be persistent. One or more embodiments of the RAM disk include an “image” file on a non-volatile storage device (e.g., a disk) other than the RAM disk device. The image file is populated with data contained in the RAM disk prior to shutting down the RAM disk. Then upon restart, a similar RAM disk is created in main memory and the data from the image file is recopied to the new RAM disk. The RAM disk can be created while the operating system is initializing (“booting”). The RAM disk will appear to users and computer applications to be the same before and after the shutdown and restart cycle. Therefore, users do not need to create a RAM disk and re-establish it after restart (“reboot”) to contain all the information they were working on before shutdown. This may be performed during the time between the end of the operating system's initialization and the beginning of its shutdown. Other embodiments include a method for backing up data in the RAM disk during operation by “writing-through” data from the RAM disk to the non-volatile disk device when the RAM disk is in use. Some embodiments include a method

Backup storage disk; and signaling the operating system that it is permitted to shut down the operating system when the image file backup is complete. The backup storage disk is a magnetic storage disk in some embodiments. A method for restoring a RAM disk in main memory from a RAM disk image file on a backup storage disk is also described. Some embodiments include locating the image file on the backup storage disk following system boot-up; creating a RAM disk in main memory (RAM); allowing asynchronous and substantially simultaneous access to the image file on the backup disk and on the RAM disk, so that the combination of the two are available for simultaneous access during both system boot-up or subsequent shutdown before the RAM disk is fully populated from the image file. Other methods described here are directed to restoring from the RAM disk an image file on the backup disk to the RAM disk in main memory, including enabling access to the combined image file and RAM disk so that even though the RAM disk is not fully populated with the image file data, users or other operating system accesses to the combination of the two do not have to wait for the RAM disk to be fully populated in order to access the data stored originally in the image file. In the previous method, the process can include allowing operating system to shutdown, even though the previous restoration of the RAM disk from the image file wasRAM Disk for ARM64 - RAM Disk Help - SoftPerfect
File system. An important feature is that the RAM disk it creates is available to the system very early in system startup. Therefore, any applications or services that depend on the RAM disk can access it as soon as they start. Keep your temporary files in the fastest storage to get the highest performance, and forget about hard disk fragmentation caused by undeleted temporary files. The RAM disk can improve overall system performance. The temporary files frequently accessed by system or other application, and the read and write the RAM memory speeds far greater than the real hard disk, so the RAM disk can improve overall system performance; additional hard disk, and SSD storage medium has its read and write times limit, the RAM disk improve the life of a real hard disk too. Secure disk Secure disk is a compact program for creating on-the-fly-encrypted virtual disks. It helps you protect your sensitive files or data from unauthorized access with strong Encryptions. You can create a new volume which reside in a file, and mount it as a virtual disk. File operations on the virtual disk just like they are on any normal disk. Files that are being written/ read on virtual disk are automatically being encrypted/ decrypted on-the-fly, without any user intervention.

For allowing access to the data associated with the RAM disk before the RAM disk is fully restored on reboot, e.g., in the time between initialization of the system and full restoration of a RAM disk from the image file. Here, the operating system and programs are allowed asynchronous access to information belonging in the RAM disk, whether it is already loaded into the RAM disk, or whether it still physically resides in a disk image file pending loading into the RAM disk. By moving data to and from the RAM disk in relatively large block sizes, e.g., on the order of megabytes (MB), such as 4 MB, the speed of establishing an image file and/or a RAM disk is increased to reduce latency and wait time. This feature is especially useful in larger RAM disks, e.g., in an enterprise system having a RAM disk size on the order of 1 GB. Accordingly, one or more embodiments described herein are directed to a method for backing up a RAM disk to a specified backup disk volume, the disk being a persistent storage device other than main memory. This method includes intercepting an I/O request packet (IRP) from the operating system that indicates that the operating system is ready to shut down; blocking or delaying the shutdown of the operating system to allow backup of the RAM disk to the image file on the backup storage device; making an image copy of the RAM disk to the image file on theVolatile RAM disks - RAM Disk Help - softperfect.com
Blind Guardian Superspeed offers two high-performance RAM disk products: RamDisk and RamDisk Plus.RamDisk and RamDisk Plus®: Vista 32 & 64-bit CertifiedBoth 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 be shared so as to be accessed by other computers on a network.XP 32 & 64-bit Certified: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.

2025-03-28It all depends on what you want to achieve and how you use those systems. Since I don't know how you are using them, the following advice is rather generic.As far as I understood, you have Windows 2019 host running Windows 2003 guest in VMWare and you want them to use RAM disk as much as possible to spare the NVM drive. In that case you would probably need two instances of the RAM disk app: one on the guest OS and one on the host OS. Sharing a RAM disk on the host via shared folders would likely be too slow.For general use you could create one RAM disk in the guest VM and one RAM disk on the host, depending on how much free RAM you have. Then redirect temporary files and browser caches to those drives in both systems respectively. Depending on what you use those systems for there may be other folders that you could move to the RAM disk.Another approach may be to run the guest OS entirely from a RAM disk. For that, you could create a RAM disk large enough to hold your guest machine VMDK file. Copy the VMDK disk image to the RAM disk and boot the VM from it. Then any I/O from the guest would end up in the RAM disk and the guest OS will run extremely fast due to high-speed storage.The downside to that is it's a volatile RAM disk - everything is gone upon reboot, including any changes written to the VMDK image. To work around that, you could create a persistent RAM disk, though data loss is still possible in case of a crash or power loss.
2025-04-09Information in RAM is subject to loss upon powering down the device. Disks usually store information in permanent, persistent, non-volatile form, such as by encoding magnetic regions of a disk or tape in a way that can tolerate loss of electrical power without losing the data stored in a disk. To enhance the performance (speed) of computers, systems using RAM have been designed to emulate a disk partition in the computer's RAM. This is generally referred to as a “RAM disk,” implying that the RAM is effectively being used as a disk storage device. RAM disks provide file access in a way analogous to file access on a disk. Software is used to create and manage the RAM disk so that the operating system of the computer treats that portion of RAM as it would treat an actual disk drive connected to the computer. Since RAM access is much faster than disk access, RAM disks are especially useful to improve the speed of applications that perform frequent memory access operations. SUMMARY RAM disks and methods are described for use in computer systems, including stand-alone computers and networked or clustered computer systems. Computer-readable media including software instructions for setting up and operating the RAM disks are also included in this disclosure. The instructions may be executed on one or more processors in a computing environment having an operating system such as the Windows 2000, Windows XP, or Windows Server 2003 operating systems from Microsoft Corporation of Redmond, Wash.
