Report On Raid Hard Drive

The use of data in today’s commercials is a vital role that cannot be overlooked. That is there is a need to backup data on physical mediums. The main mediums are hard-drive, flash drive, optical disc, and tape drive. There is multiply different version of each main type of medium. These different physical mediums store data in different ways. Fragmentation can also be an issue for some of these physical mediums. I will cover each medium in a little depth because of the different types available in today’s market.

It is not only responsible for storing data but also to provide security along with it. It also allows accessing data effectively; integrating data to enhance service intelligence, analysis based on the services required and most importantly increases the storage efficiency.

SATA stands for Serial AT Attachment is another computer bus interface. It has a hot plugging interface that allows connecting to different storage devices like hard disk drivers or optical

Reduce time to access the required data: DDBMS allows to store copies of a data in multiple branches.

Using the sequential I/O we can optimize the performance of our configuration. For writing the intensive fields its better to avoid either RAID 5 or RAID 6 rather than that we can use RAID 1 or 10.

In RAID 3 the disks spin in sync where all the read write operations are done with high performance.

Storage Devices connect to the motherboard using AT Attachment (ATA). Like RAM, ATA use busses to transfer data. Older storage devices use PATA (Parallel ATA), which have a bus width of 16 bits (2 bytes) and as such have slow data transfer speeds (up to 133 Mbit/s). The more modern SATA (Serial ATA) was released January 7, 2003, and has much higher transfer speeds. As of now, five types of SATA are available: SATA 1.0 (1.5Gbit/s), SATA 2.0 (3Gbit/s), SATA 3.0 (6Gbit/s), SATA 3.1 and SATA 3.2.

RAID drives are combined into single logical unit that provide data redundancy with increased overall system performance. The biggest advantage of using a RAID system is that it has fault tolerance ability that enables a system to perform all the functions, even when one or more hard drives have failed. There are multiple ways to distribute data in a RAID system that has been classified into different RAID levels.

One of the most common questions that you find on Google is whether or not having drives in a RAID 0 array can later be converted to RAID 5. Some people have manually copied things in this drive as a form of getting some type of backup, but having a complete backup of RAID 0 can be tricky. Can you convert a RAID 0 to a RAID 5? For some people, RAID 5 sounds appealing because you can have 6TB instead of having just four for your backup.

It is the type of disk in which the space is fixed. it doesn’t matter how much data you store.

When IBM first developed the AS/400, storage (both main and disk) was expensive relative to today, and so companies wanted to minimize the amount they stored. IBMs storage architecture reflected this reality, and therefore the data written to disk was highly refined, or structured.

In this region, the directory table that saves information about the files and directories located in the root directory region is included. When the volume is formatted, the size of this region allocated to fixed maximum size. This regions is only used in FAT 12 and FAT 16. the root directory entries in FAT 32 is stored as another sub directories in its data region.

Level 1 is the highly capable individual. The highly capable individual is the productive contributor. The individual offers their talent, knowledge, and skills. He/ She have good working habits. Level 2 is the contributing team member. The individual contributes to ensuring the achievements of the team objectives. The contributing team member works effectively

Physical data store level: The data storage infrastructure where the users are able to share, store and access the same data store.

Also, there is option of SAS or SAS hard drives which provide the facility to user up to 12Gbps interface and 16MB of cache. Provide rotation speed of 10K/15K RPMs. SAS options available from 300GB up to 6TB.
