Addressable elements of memory
4 Gbyte file transfer
Data transfer is crucial for various organizations such as research institutions, security intelligence, and medical fields among other companies. Initially, file transfers allowed the exchange of smaller files limiting the capabilities of the various organizations (Arsan et al., 2014). However, the introduction of the 4 Gigabyte file transfer has revolutionized several agencies today. The different groups have reported improved services as well as revenues. Besides, the costs of acquiring the technology for data transfers have reduced significantly (Arsan et al., 2014). Timing is the other key change in the file transfer technology. Today, the timing for the transmission of the data has reduced significantly thus facilitating seamless information exchange between the various parties.
Zone Biting Sector
Zone bit recording is a technology that focuses on the storage of sectors per track on the other tracks more than on the inner tracks (Sammes, Jenkinson, & Paul, 2000). A hard disk that uses this technology can facilitate higher data transfers, in particular on the outside zone. It is also the place where the operating system stores its files after its initial installation. The main disadvantage of the technology is the significant drop in the data transfer rate when more data is added. However, new technologies address the issue of reduced data transfer rates by reducing the rate of spinning of the medium instead (Sammes, Jenkinson, & Paul, 2000). As a result, the data transfer rate is maintained. Therefore, the use of Zone bit recording is correct as compared to other storage media regarding the speed of data transfer.
Interfaces within Hard drives
Drive interfaces are crucial because they help in the integration of disk drives to computer systems from various vendors. Therefore, it is important to have standard interfaces that can support the various systems. As a result, the hard drive interfaces have evolved over time to accommodate the various computer systems. Storage Module Device was the standard interface used for mini-computer in the 1970s and 1980s. Shugart Associates System Interface (SASI) was used for in the 1980s for small GDDs. Enhanced Small Disk Interface (ESDI) boasts of higher data rate transfers. Small Computer System Interface (SCSI) replaced the ESDI in the mid-1980s. (Parallel) AT Attachment (P) ATA is a standard HDD interface used by several enterprises. Serial Attached SCSI (SAS) replaced the SCSI due to improved standardization. Serial ATA (SATA) is the most common interface in all companies (Sammes, Jenkinson, & Paul, 2000). It is the best because it supports all the current systems today.
Shift from Floppy Disks to Hard Drives
Storage space is one of the major factors that determine the type of
storage for individual or organizational storage. The demand for better and
improved storage media leads to the development newer and better storage media.
For instance, people shifted from floppy to hard drive due to storage issues.
The highest storage space for a floppy disk is 1.2MB which is lower compared to
a hard disk that supports up to 1 Terabyte(TB) (Sammes, Jenkinson, & Paul,
2000). Besides, the use of hard drives eliminates the need for more space to
accommodate the many floppy disks that may be required to support the needs of
the organization. Furthermore, hard drives support the installation of many
operation systems in one hard disk thus allowing running various applications
from different vendors.
