Discuss what physical computer storage is and various storage methods.

[Kanthony]

Welcome to Week 3!

This week be sure to read chapters 6-8 and watch chapters 6-8 videos. 

Don’t forget to do the Week 3 Devotional and discussion Questions. 

Finally, submit chapters 7-9 chapter exams. 

Please email me with any questions.~Dr. Anthony

Billy Graham Devotion

The heavens declare the glory of God; and the firmament sheweth his handiwork. Day unto day uttereth speech, and night unto night sheweth knowledge. There is no speech nor language, where their voice is not heard.
—Psalm 19:1–3

There is a language in nature that speaks of the existence of God. It is the language of order, beauty, perfection, and intelligence. Some time ago a scientist told me that when he gave serious thought to the majestic order of the universe and its obedience to unchanging law, he could not help but believe in God. He had become aware that God was speaking through nature.

God speaks in the certainty and regularity of the seasons; in the precision of the movements of the sun, the moon, and the stars; in the regular coming of night and day; in the balance between man’s consumption of life-giving oxygen and its production by the plant life of the earth; and even in the cry of a newborn child with its ever-new dimension of the miracle of life.

Physical computer storage is a physical device used to store data and software. Some physical storage devices include things like hard drives RAID storage and compact disks. Hard drives can be solid or magnetic. RAID or Redundant Array of Independent Disks is a method of storage where multiple storage disks act as one to improve performance. Raid has multiple variations designed to improve data loss prevention. Compact disks or CD-ROM are used to store data like music. These optical drives are the most likely to have errors due to simple things like dust, fingerprints, or scratches on the disk itself.

Physical storage, commonly known as local storage, involves saving files on local servers or devices (such as hard disk drives (HDDs), solid-state drives (SSDs), and USB flash drives) that are directly controlled and operated by users. HDDs use magnetic storage with rotating disks to read and write data, while SSDs have no moving parts and use flash memory for faster data access. Other physical storage methods include optical disks such as CDs and DVDs, and magnetic tapes, which, despite their age, are still used for large-scale data archiving due to their large capacity and long lifespan. Each storage method has different advantages in terms of speed, capacity, cost, and durability, and can meet various data storage needs. Physical storage devices are essential components of computer systems used for retention and retrieval of digital data. Each type of storage has its own distinct advantages and disadvantages, resulting in their use in various applications.

When looking into an example motherboard and reading this lecture can teach us about the differences between the physical drive and flash drive. Amazing how a system can use both drives to operate functionally.

[Jacob Mannon]

I think it is interesting how much more fragile optical disks are than other means of storage, The CDs and DVDs that we use can easily not read properly if they are scratched or have to much dust on them. Streaming services are also seeming to make them more obsolete.

[Matt McShane]

There happens to be two different disk drive states in an operating system and other applications: Hard disk drive (HDD) and the solid-state drive (SDD). HDD are physical drives which with the read/write heads will, as in its title, read data and write data to store it on the OS system. SSD are memory drives where there is no physical part to read data, but essentially memorize on a device almost like a SD card-chip. One other drive is a hybrid drive where it has the combination of a magnetic hard drive while also having the flash memory of a solid-state drive with it. Benefits of this drive include a faster boot and app speed and also much bigger storage on the computer.

[Mjulius513]

Hey, faster boot times can significantly enhance the computing experience. This means less time waiting and more time being productive or engaged. Optimization of the system is achieved through an integration of hardware upgrades and software refinements. On the hardware side, solid-state drives (SSDs) have revolutionized boot speeds compared to traditional hard disk drives (HDDs).
