Week 1
The text discusses examples of traditional mass storage such as magnetic disk and
solid-state drives. While these still underpin most mass storage, in corporate
environments, they are often accessed via Network Attached Storage (NAS) or
Storage Area Network (SAN) technologies. Find and summarise ONE resource that
describes EITHER NAS or SAN storage technologies. The resource and your
summary must focus on either NAS or SAN, NOT BOTH.
Network Attached Storage:
Liu, C. & Chen, H., 2009. Network Attached Storage. U.S. Patent Application, 29(250), p.435.
Summary:
The selected resource written by (Liu & Chen, 2009) is all about network attached
storage which is a useful way of mass storage. It has been selected to understand
the key features of NAS while comparing it with other mass storage techniques like
solid-state drives, magnetic disk as well as SAN. The author of the article narrated
network attached storage technologies to explain its significance in mass storage
over a network server. Main points of this article suggest that NAS act as a data
storage device based on file-level which is linked to a TCP/IP network, or Ethernet.
The article states that NAS generally utilizes CIFS and NFS protocols, even when
the choices like HTTP are available. Additionally, key information which has been
presented by this paper suggest that NAS is exactly like an operating system (OS) as
a mutual folder through which employees and persons can access data files using
the NAS as they access from any other file on the network (Liu & Chen, 2009).
However, this resource highlighted NAS as LAN-dependent; thus if the LAN goes
down then the NAS will also go down. Apart from this, the chosen study on NAS
revealed that NAS does not work as quick as block SAN, yet high-speed LANs can
easily be utilized for overcoming every performance and latency issue. Chosen
resource highlighted the major differences amid NAS and SAN like fabric, protocols,
data processing, performance, scalability, price, and ease of management. In this
way, this resource was useful as it was detailed on NAS while offering the details of
the usability of NAS over alternative storage technologies from focusing on NAS
unique mass storage capabilities.

Operating systems use file managers to interact with mass storage devices.
However, the way in which data is stored and retrieved is dictated by the file system.
There are many types of file systems used by modern operating systems. Find and
summarise ONE resource that describes ONE such file system that is NOT FAT,
FAT32 or ExFAT. The resource, and your summary must focus on A SINGLE file
system.
Analysis and implementation of NTFS file system based on computer forensics :
Kai, Z., En, C. & Qinquan, G., 2010. Analysis and implementation of NTFS file system based on
computer forensics. Second International Workshop on Educational Technology and Computer
Science, 1, pp.325-28.
Summary:
The selected resource article is about NTFS type of file system that is typically based
upon computer forensics. This article has been chosen because the author has
presented an illustrated detailed research on the analysis as well as the
implementation of NTFS files system. The analysis done in this paper has covered
the major process through which operating systems interact with mass storage
devices in the digital era. This paper has highlighted the ways in which mass data is
stowed as well as retrieved by the different kinds of the file system.
The research paper written by (Kai et al., 2010), included a study about NTFS file
system being a New Technology File System through comprising the primary
features of the NTFS file system within the different OS. While assessing the chosen
article’s main findings it has been found that name conventions of the files in NTFS
can contain up to 255 characters provided they are not case sensitive. Moreover, the
major points in the study written by (Kai et al., 2010) suggested that file names in
NTFS file system can contain all of the characters excluding / “> < * | :. On the other
hand, this paper has explained the NTFS system being a secure system for storing
files as well as folders safely for a long time. Key info covered in this study is
suggesting that stowed data in the form of files and folders are more secure than
those of the FAT file system. Hence, the selected resource was useful to understand
the key features and importance of NTFS file system over others.
