Top 10 List of Week 09

1. Mass Storage Structure
   Each modern disk contains concentric tracks and each track is divided into multiple sectors. The disks are usually arranged as a one dimensional array of blocks, where blocks are the smallest storage unit.Blocks can also be called as sectors. For each surface of the disk, there is a read/write desk available.

2. HDD Scheduling
   Disk Scheduling Algorithms are used to reduce the total seek time of any request.

3. NVM Scheduling
   The NVM device is physically attached to the Booster Nodes (BN) and provides local high-performance data storage.

4. Error Detection and Correction
   This video will explain about transmission errors, types of error, error detection and correction, also about its technique.

5. Storage Device Management
   This video was made by University of South Carolina and will explain about Storage Device Management in Operating System.

6. Swap-Space Management
   This video will explain disk management in OS especially about Swap-Space Management and Reliability.

7. Storage Attachment
   Computers access disk storage in two ways. One way is via I/O ports (or host-attached storage); this is common on small system. The other way is via a remote host in a distributed file system; this is reffered to as network-attached storage.

8. RAID Structure
   This video will explain RAID in operating system, general RAID levels, and comparison between RAID levels. RAID is the technique in which we use multiple physical hard-drives together as a single logical hard-drive.

9. Disk Scheduling Algorithm
   Disk-scheduling algorithms can improve the effective bandwidth of HDDs, the average response time, and the variance in response time. Algorithms such as SCAN and C-SCAN are designed to make such improvements through strategies for disk-queue ordering. Performance of diskscheduling algorithms can vary greatly on hard disks. In contrast, because solid-state disks have no moving parts, performance varies little among scheduling algorithms, and quite often a simple FCFS strategy is used. URL provided will explain more about this topic, please check it out!

10. Object Storage
    Object storage is used for big data problems such as indexing the Internet and cloud photo storage. Objects are self-defining collections of data, addressed by object ID rather than file name. Typically it uses replication for data protection, computes based on the data on systems where a copy of the data exists, and is horizontally scalable for vast capacity and easy expansion.
