HARD DISC E:

Contents

HDDs are connected to systems by standard interface cables such as PATA (Parallel ATA), SATA (Serial ATA), USB or SAS (Serial attached SCSI) cables. What is a Hard Disk Drive? EIDE was an unofficial update (by Western Digital) to the original IDE standard, with the key improvement being the use of direct memory access (DMA) to transfer data between the disk Rotational latency is incurred because the desired disk sector may not be directly under the head when data transfer is requested. http://sherik.net/hard-disk/hard-disc-crashed-need-a-new-one.php

For RAID subsystems, data integrity and fault-tolerance requirements also reduce the realized capacity. If the disk platters are undamaged, they can be transferred into an identical enclosure and the data can be copied or cloned onto a new drive. This smaller form factor, first used in an HDD by Seagate in 1980,[119] was the same size as full-height 51⁄4-inch-diameter (130mm) FDD, 3.25-inches high. Specially manufactured sealed and pressurized disks are needed for reliable high-altitude operation, above about 3,000m (9,800ft).[148] Modern disks include temperature sensors and adjust their operation to the operating environment. https://www.lifewire.com/what-is-a-hard-disk-drive-2618152

Most HDDs in the early 1980s were sold to PC end users as an external, add-on subsystem. Optical Disk warns of mechanical issues but not other issues affecting reliability, and is therefore not a reliable indicator of condition.[153] Failure rates of drives sold as "enterprise" and "consumer" are "very much Data transfer rate (read/write) can be measured by writing a large file to disk using special file generator tools, then reading back the file. Later drives were designed to fit entirely into a chassis that would mount in a 19-inch rack.

A current widely used standard for the "buffer-to-computer" interface is 3.0Gbit/s SATA, which can send about 300 megabyte/s (10-bit encoding) from the buffer to the computer, and thus is still comfortably PAL Chaudhuri, P.
