DVD-RAM appeared as a successor technology in April 1997, DVD-RAM adopts a cartridge similar to PD, and the 2.6 GB version 1.0 standard, which has just one side capacity equal to 4 times the PD, DVD - It was possible to read and write PD in the RAM drive. However, in the summer of 2000, compatibility with PD was not taken into consideration ...
The drive was still completely incompatible with PC drives. The 800 KB drive has two read/write heads, enabling it to simultaneously use both sides of the floppy disk and thereby double storage capacity. Like the 400 KB drive before it, a companion Macintosh 800K External Drive was an available option. However, with the increased disk storage ...
A RAM drive innovation introduced in 1986 but made generally available in 1987 [3] [4] by Perry Kivolowitz for AmigaOS was the ability of the RAM drive to survive most crashes and reboots. Called the ASDG Recoverable Ram Disk, the device survived reboots by allocating memory dynamically in the reverse order of default memory allocation (a ...
i-RAM Version 1.3 PCI-Card with 4 x 1 GB DIMM. The i-RAM [1] was a PCI card-mounted, battery-backed RAM disk that behaved and was marketed as a solid-state storage device. It was produced by Gigabyte and released in June 2005, [2] at a time when genuine solid-state storage solutions were generally still less affordable than an i-RAM product with superficially similar capabilities.
DVD-RAM (DVD Random Access Memory) is a DVD-based disc specification presented in 1996 by the DVD Forum, which specifies rewritable DVD-RAM media and the appropriate DVD writers. DVD-RAM media have been used in computers as well as camcorders and personal video recorders since 1998.
The SMD family became the predominant disk drive in the minicomputer market into the 1980s. Also in 1973, IBM introduced the IBM 3340 "Winchester" disk drive and the 3348 data module, the first significant commercial use of low mass and low load heads with lubricated platters and the last IBM disk drive with removable media. This technology and ...
The product was released for sale in the mid-1980s. The disk drive can be used with Hitachi Maxell 2.8-inch double sided floppy disks, with a capacity of 144 kilobytes non-formatted and 100 kilobytes formatted. Each side has 20 sectors of 2.5 kB [1] [2] written in a spiral pattern instead of the more usual circular tracks.
