RDX (disk)
RDX is a disk-based removable storage format intended as a replacement of tape storage. RDX removable disk technology consists of portable disk cartridges and an RDX dock. RDX cartridges are shock-proof 2.5-inch Serial ATA hard disk drives and are advertised to sustain a drop onto a concrete floor and to offer an archival lifetime up to 30 years and transfer up to 650GB/hr. The technology was developed by ProStor Systems Incorporated in 2004. In May 2011, Tandberg Data GmbH of Germany acquired the RDX business including intellectual property and key members of ProStor's RDX engineering team. Hard disk cartridges capacities are 320 GB, 500 GB, 1 TB, 1.5 TB, 2 TB, 3 TB, 4 TB, and 5 TB. Solid-state cartridges' capacities run from 64 GB to 512 GB per medium, doubling each increment; or as WORM media from 320 GB to 1 TB. Dell markets RDX cartridges under the trade name RD1000; a teardown reveals they contain a standard laptop drive enclosed with silicone bumpers, but the drive ...

Tandberg RDX Cartridge (1) 2022-09-01
Tandberg was an electronics manufacturer located in Oslo, Norway (production, sales and distribution) and New York City, United States (sales and distribution). The company began in the radio field, but became more widely known for their reel-to-reel tape recorders as well as cassette decks and televisions. The original company went bankrupt in 1978, after a sharp financial downturn. The following year, the company re-formed whilst their data division was split off as Tandberg Data, including the tape recording division, which reduced its scope to data recording. Over time the original Tandberg company became increasingly involved in the teleconferencing systems, and became a leader in that field. The company's main competitor was Polycom and other competitors were Hewlett-Packard, HP, Sony, Radvision Ltd., Radvision, VTEL and Aethra Telecommunications, Aethra. Cisco Systems acquired Tandberg on 19 April 2010. Tandberg Data became a Germany, German company dedicated to making ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Computer Data Storage
Computer data storage or digital data storage is a technology consisting of computer components and Data storage, recording media that are used to retain digital data. It is a core function and fundamental component of computers. The central processing unit (CPU) of a computer is what manipulates data by performing computations. In practice, almost all computers use a storage hierarchy, which puts fast but expensive and small storage options close to the CPU and slower but less expensive and larger options further away. Generally, the fast technologies are referred to as "memory", while slower persistent technologies are referred to as "storage". Even the first computer designs, Charles Babbage's Analytical Engine and Percy Ludgate's Analytical Machine, clearly distinguished between processing and memory (Babbage stored numbers as rotations of gears, while Ludgate stored numbers as displacements of rods in shuttles). This distinction was extended in the Von Neumann archite ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Magnetic Tape Data Storage
Magnetic-tape data storage is a system for storing digital information on magnetic tape using digital recording. Tape was an important medium for primary data storage in early computers, typically using large open reels of 7-track, later 9-track tape. Modern magnetic tape is most commonly packaged in cartridges and cassettes, such as the widely supported Linear Tape-Open (LTO) and IBM 3592 series. The device that performs the writing or reading of data is called a tape drive. Autoloaders and tape libraries are often used to automate cartridge handling and exchange. Compatibility was important to enable transferring data. Tape data storage is now used more for system backup, data archive and data exchange. The low cost of tape has kept it viable for long-term storage and archive. Open reels Initially, magnetic tape for data storage was wound on reels. This standard for large computer systems persisted through the late 1980s, with steadily increasing capacity d ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Removable Media
In computing, a removable media is a data storage media that is designed to be readily inserted and removed from a system. Most early removable media, such as floppy disks and optical discs, require a dedicated read/write device (i.e. a drive) to be installed in the computer, while others, such as USB flash drives, are plug-and-play with all the hardware required to read them built into the device, so only need a driver software to be installed in order to communicate with the device. Some removable media readers/drives are integrated into the computer case, while others are standalone devices that need to be additionally installed or connected. Examples of removable media that require a dedicated reader drive include: * Optical discs, e.g. Blu-rays (both standard and UHD versions), DVDs, CDs * Flash memory-based memory cards, e.g. CompactFlash, Secure Digital, Memory Stick * Magnetic storage media ** Floppy and Zip disks (now obsolete) ** Disk packs (now obsolete) ...

Serial ATA
SATA (Serial AT Attachment) is a computer bus interface that connects host adapter, host bus adapters to mass storage devices such as hard disk drives, optical drives, and solid-state drives. Serial ATA succeeded the earlier Parallel ATA (PATA) standard to become the predominant interface for storage devices. Serial ATA industry compatibility specifications originate from the Serial ATA International Organization (SATA-IO) which are then released by the INCITS Technical Committee T13, AT Attachment (INCITS T13). History SATA was announced in 2000 in order to provide several advantages over the earlier PATA interface such as reduced cable size and cost (seven conductors instead of 40 or 80), native hot swapping, faster data transfer through higher signaling rates, and more efficient transfer through an (optional) I/O queuing protocol. #1.0, Revision 1.0 of the specification was released in January 2003. Serial ATA industry compatibility specifications originate from the S ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hard Disk Drive
A hard disk drive (HDD), hard disk, hard drive, or fixed disk is an electro-mechanical data storage device that stores and retrieves digital data using magnetic storage with one or more rigid rapidly rotating hard disk drive platter, platters coated with magnetic material. The platters are paired with disk read-and-write head, magnetic heads, usually arranged on a moving actuator arm, which read and write data to the platter surfaces. Data is accessed in a random-access manner, meaning that individual Block (data storage), blocks of data can be stored and retrieved in any order. HDDs are a type of non-volatile storage, retaining stored data when powered off. Modern HDDs are typically in the form of a small disk enclosure, rectangular box. Hard disk drives were introduced by IBM in 1956, and were the dominant secondary storage device for History of general-purpose CPUs, general-purpose computers beginning in the early 1960s. HDDs maintained this position into the modern er ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tandberg Data

Solid-state Drive
A solid-state drive (SSD) is a type of solid-state storage device that uses integrated circuits to store data persistently. It is sometimes called semiconductor storage device, solid-state device, or solid-state disk. SSDs rely on non-volatile memory, typically NAND flash, to store data in memory cells. The performance and endurance of SSDs vary depending on the number of bits stored per cell, ranging from high-performing single-level cells (SLC) to more affordable but slower quad-level cells (QLC). In addition to flash-based SSDs, other technologies such as 3D XPoint offer faster speeds and higher endurance through different data storage mechanisms. Unlike traditional hard disk drives (HDDs), SSDs have no moving parts, allowing them to deliver faster data access speeds, reduced latency, increased resistance to physical shock, lower power consumption, and silent operation. Often interfaced to a system in the same way as HDDs, SSDs are used in a variety of devices, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Write Once Read Many
Write once read many (WORM) describes a data storage device in which information, once written, cannot be modified. This write protection affords the assurance that the data cannot be tampered with once it is written to the device, excluding the possibility of data loss from human error, computer bugs, or malware. On ordinary (non-WORM) data storage devices, the number of times data can be modified is limited only by the lifespan of the device, as modification involves physical changes that may cause wear to the device. The "read many" aspect is unremarkable, as modern storage devices permit unlimited reading of data once written. Historical exceptions include time-limited discs such as Flexplay, designed for short-term rental of movies; and early non-volatile memory technologies such as magnetic-core memory and bubble memory, from which reading data also erased it. WORM prevents important data being deleted or modified, helping to preserve its authenticity. History WORM dr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
