12 Facts About RAM disk

Performance of a RAM drive is generally orders of magnitude faster than other forms of digital storage, such as SSD, tape, optical, hard disk, and floppy drives.

Second, the maximum throughput of a RAM disk drive is limited by the speed of the RAM disk, the data bus, and the CPU of the computer.

Storage is in RAM disk, it is volatile memory, which means it will be lost in the event of power loss, whether intentional or accidental.

In many cases, the data stored on the RAM disk drive is created from data permanently stored elsewhere, for faster access, and is re-created on the RAM disk drive when the system reboots.

Apart from the risk of data loss, the major limitation of RAM disk drives is capacity, which is constrained by the amount of installed RAM disk.

Usually no battery backup is needed due to the temporary nature of the information stored in the RAM disk drive, but an uninterruptible power supply can keep the system running during a short power outage.

RAM disk drive innovation introduced in 1986 but made generally available in 1987 by Perry Kivolowitz for AmigaOS was the ability of the RAM disk drive to survive most crashes and reboots.

The super-block, and all other RRD RAM disk "blocks" maintained check sums to enable the invalidation of the RAM disk if corruption was detected.

Many Unix and Unix-like systems provide some form of RAM disk drive functionality, such as on Linux, or md on FreeBSD.

RAM disk drives are particularly useful in high-performance, low-resource applications for which Unix-like operating systems are sometimes configured.

An early example of a hardware RAM disk drive was introduced by Assimilation Process, Inc in 1986 for the Macintosh.

The drive is a primary 4GB DDR dedicated RAM disk drive for regular use, which can back up to and recall from a 4GB SLC NAND drive.
