RAM drives use normal system memory as if it were a partition on a physical hard drive rather than accessing the data bus normally used for secondary storage. Though RAM drives can often be supported directly in the operating system via special mechanisms in the OS kernel, it is generally simpler to access a RAM drive through a virtual device ...
RAM drive software allows part of a computer's RAM (memory) to be seen as if it were a disk drive, with volume name and, if supported by the operating system, drive letter. A RAM drive has much faster read and write access than a hard drive with rotating platters, and is volatile, being destroyed with its contents when a computer is shut down ...
Windows can be configured to use free space on any available drives for page files. It is required, however, for the boot partition (i.e., the drive containing the Windows directory) to have a page file on it if the system is configured to write either kernel or full memory dumps after a Blue Screen of Death. Windows uses the paging file as ...
Software can "partition" a portion of a computer's RAM, allowing it to act as a much faster hard drive that is called a RAM disk. A RAM disk loses the stored data when the computer is shut down, unless memory is arranged to have a standby battery source, or changes to the RAM disk are written out to a nonvolatile disk.
i-RAM – a DRAM-based solid-state storage device produced by Gigabyte, operating as a SATA hard disk drive; Mass storage – High capacity computer storage devices; Magnetic storage – the concept of storing data on a magnetised medium using different patterns of magnetisation
Non-volatile random-access memory (NVRAM) is random-access memory that retains data without applied power. This is in contrast to dynamic random-access memory (DRAM) and static random-access memory (SRAM), which both maintain data only for as long as power is applied, or forms of sequential-access memory such as magnetic tape, which cannot be randomly accessed but which retains data ...
HyperDrive (HD) is a series of RAM-based solid-state drives invented by Accelerated Logic B.V. (became Accelerated Logic Ltd. and is now a German company) [1] employee Pascal Bancsi (for HyperDrive II architecture), [2] who partnered with the British company HyperOs Systems, who manufactured the retail product.
USB 2.0 and faster flash drives have faster random access times: typically around 1 ms, compared to 12 ms for mainstream desktop hard drives. [18] On laptop computers, the performance shifts more in favor of flash memory when laptop memory is more expensive than desktop memory; many laptops also have relatively slow 4200 rpm and 5400 rpm hard ...
