Apart from the more common Universal Serial Bus (USB) and FireWire 400, another external interface used in data transfer is eSATA. eSATA simply means External Serial Advanced Technology Attachment.
It is used for SATA technologies. In fact, SATA is considered as the next generation of internal bus interfaces for hard drives. This technology has been proven as more streamlined than its predecessors. It can provide greater transfer speeds through its serial structural design.

A SAN (Storage Area Network) is a network specifically dedicated to the task of transporting data for storage and retrieval. SAN architectures are alternatives to storing data on disks directly attached to servers or storing data on Network Attached Storage (NAS) devices which are connected through general purpose networks.
In order to meet the demands of the storage system, enterprises apply SAN to increase the system efficiency and capacity expansion. According to SNIA (Storage...

A HBA, or Host Bus Adapter, is the interface card which connects a host to a SAN (Storage Area Network). It is an electronic circuit board and/or integrated circuit adapter that offers input/output (I/O) operations and physical connectivity among a server and a storage device.
Presently, the phrase Host Bus Adapter (HBA) is frequently used for Fibre Channel interface cards. Fibre Channel HBAs are obtainable for all key open systems, computer architectures, and buses. Every HBA has a...

Computer wire connections have been redefined and reset with the emergence of the universal serial bus or USB. Nowadays, almost all modern computers are equipped with USB terminals. Consumers or new computer buyers should always make sure that the personal computer units they will be purchasing have USB terminals. That is because almost all wires and memory storage gadgets that must be plugged to the PC are having USB capabilities.
The SCSI or small computer system interface wiring systems...

What is a Sector?
A sector is a small area on the surface of a hard drive or a floppy disk.
Hard drives usually have several platters. The platters are the discs which are covered with magnetic material which is used to hold data. Floppy disk drives contain only one platter.
Platters are divided into a set of concentric rings called tracks. A 1.44MB floppy disk has 160 tracks. Hard drives have thousands of tracks.
Each of these tracks is divided into smaller storage areas called...

RAID stands for Redundant Array of Independent Disks and it basically involves combining two or more drives together to improve the performance and the fault tolerance. Combining two or more drives together also offers improved reliability and larger data volume sizes. A RAID distributes the data across several disks and the operating system considers this array as a single disk. RAID Levels
Several different arrangements are possible and different standard schemes have evolved which...

Serial ATA is an enhancement to the ATA standard for for connecting storage to PC's.
All versions of ATA up until ATA-7 in 2004 utilized parallel transfer of data from the motherboard to the drive controller built onto the disk.
The ATA-7 specification introduced Serial ATA.Serial ATA Standards
The original Serial ATA standard offered miniminal improvement over the existing 133MBps bandwidth of the existing Parallel ATA standard.
Serial ATA standards are constantly evolving to meet higher...

Fibre Channel is a set of standards for connecting storage devices in a fabric network. The Fibre Channel standard identifies a protocol and a collection of physical interfaces for managing computer peripheral components. The key purpose of this standard is managing large numbers of storage devices. Fibre Channel makes use of serial interfaces working at symbol rates from 133MB/s up to 4.25Gb/s. Optical as well as electrical signals are supported. Fibre Channel supports data...

ATA (AT Attachment) is the primary standard for connecting storage to PC's.
ATA replaced earlier technologies such as MFM, RLL, and ESDI. ATA currently competes with SCSI.
ATA is a specification for attaching hard drives to the AT bus. The AT specification has been extended to include other storage, such as CD/DVD drives, tape drives, and Zip drives with the Advanced Technology Attachment Packet Interface (ATAPI) additions to the specification.
ATA is also known as IDE (Integrated Drive...
