Physical computer storage encompasses the use of tangible devices such as hard disk drives (HDDs), solid-state drives (SSDs), USB flash drives, memory cards, and optical discs (CDs/DVDs) to retain and access data on a computer system. These devices facilitate data accessibility even in the absence of an internet connection. They employ diverse storage methods, including magnetic storage in HDDs, flash memory in SSDs and USB drives, and optical storage in CDs/DVDs, with each method being dependent on the technology used for data recording.

Hello Jessica I like the way you have described your post and it is very well put. I have used the HDDs and feel like they are good with the storage and whatnots and I know this has little to go with your post but I feel like the HDD is more secure than a USB. I have used many USBs and lost one maybe two and found them a month or so later and when we started this course I cant help but to think what if someone else would of found it thank goodness it was just pictures and not secure data.

Physical computer storage refers to the hardware components used to store digital data permanently or temporarily. The primary storage methods include Hard Disk Drives (HDDs), which use spinning disks to read/write data and are known for their large capacity and affordability. On the other hand, use flash memory to store data, offering faster access speeds and greater durability due to the lack of moving parts. Optical storage methods, such as CDs, DVDs, and Blu-ray discs, are used for media distribution and backup. And external hard drives provide portable storage solutions, making it easy to transfer data between devices. Each of these methods offers unique benefits, allowing users to choose the best option based on their needs for speed, capacity, portability, and cost.

Hello Braden,
I liked how you were able to describe hard disk drives and explain why they’re used, but solid-state drives are also becoming more advanced to where they also have a large capacity. I also thought it was interesting how you described solid-state drives as flash memory because I haven’t heard of it in that way.

Physical computer storage could also mean any physical equipment that stores digital data for the period intended for either short-term or long-term use. Thus, it forms a very important paradigm in the architecture of computers, guaranteeing deliverability on information and applications. Data in physical storage exist usually as binary code using technologies that are usually magnetic, optical, or solid-state. Physical storage may be internal or external to the computer system.
HDDs are among the major methods of storage. HDD store and retrieve data through the usage of magnetic storage. HDDs contain rotating disks coated with a magnetic material. Via an actuator arm, it reads and writes to these disks. HDDs have been, until recently, the most common form of physical storage due to the cost-effectiveness and the ability to hold large amounts of data on one drive, but they are comparatively slow compared to new technology.
SSDs are relatively new technological advances in storage. SSDs store their data in flash memory; hence, they are faster and more power-efficient compared to HDDs. Due to the fact that SSDs do not have moving parts, they are more durable and typically offer lower latency when accessing data. This makes them preferred in quite a number of modern computing environments where speed and performance are highly valued.
Another common storage medium is optical storage. Examples of such media are CDs, DVDs, and Blu-ray discs using lasers in reading and writing data on the disks. Applications include distribution for software, media, and backups, although this has declined as such due to cloud storage and other more efficient means of physical storage.
While cloud storage is not considered a physical form of storage on the user device, it does make use of physical storage systems at a remote data center. The users can access the data stored on these remote servers over the internet. Cloud storage has become quite attractive to users because of scalability and access with ease to multiple devices, as stated by Mell & Grance (2011).

Physical storage is made up of disk drives, RAID storage, optical drives, flash drives, and memory cards. Disk drives have two different types of drives, magnetic drives which have moving parts, and solid-state drives which don’t have moving parts. Solid-state drives have certain advantages including it’s quieter than magnetic drives, faster, and made in smaller form factors. RAID storage is a more complex form of storage made up of multiple magnetic disk drives that have data spread out through each drive compared to having all the data on just one drive to store it faster or more fault-tolerant. The five main types of RAID storage options mentioned in the book are RAID 0, 1, 5, 6, and 10. Optical drives are an older type of storage device that includes CDs, DVDs, and Blu-rays which commonly store music or movies. The other forms of physical storage which include flash drives and memory cards are temporary types of storage that are more convenient for mobilizing data or files.

Hey Jason,
Your explanation of physical storage is very comprehensive. I especially appreciate your detailed explanation of RAID storage and its different levels. I also found your explanation of optical drives and their evolution to be very informative. You did very well on this discussion topic.
Thanks for sharing your knowledge!

Physical storage is sometimes referred to as local storage. Physical storage includes hard disk drives, solid-state drives, and USB flash drives. Each of the physical storage drives plays a different role in storing data.
The hard disk drive works by allowing an arm to move rapidly on the disk reading and writing data in small sections called sectors. The sectors are then combined to create larger files. I hard drive can hold a range of information spanning from 500 GB to 10 TB.
Solid state drives also known as SSD can replace traditional HDD drives. One of the largest differences between HDD and SDD is that SDD is faster. SDD can load applications and save data at a fraction of the time it takes HDD. Instead of an arm SSD uses a flash controller to read, write and store data.
Another physical storage is USB Flash drives. Flash drives like SSD use a flash connector to read data yet, USB Flash drives are portable. The drive is plugged into the PC and a notification informs the user of the device. Once the user can access the device, they can then save new information or pull up stored information on the disk.

Very good explanation on what Physical storage is some of your post I didn’t realize till I read it . I have a few USB drives. It saves so much time in my belief because it can be taken from one place to another I feel like the USB are good but I don’t think they are very secure just for the fact that I have lost one maybe two and found them a month or so later. Thank goodness it was just family photos but if someone else would of found them it didn’t have any security features on it.

Computer storage is the ability to retain data in a computer system, and it is a fundamental component of any computer. There are two main types of computer storage: primary storage and secondary storage. Primary storage, also known as main memory or RAM (Random Access Memory), is fast and volatile, meaning that data is lost when the computer is turned off. Secondary storage, on the other hand, is used to store data that is not currently being used by the computer, and it is non-volatile, meaning that data is retained even when the computer is turned off. There are different types of secondary storage, including hard disk drives (HDDs), which use spinning platters to store data and offer large storage capacities at a relatively low cost. Solid-state drives (SSDs) use integrated circuits to store data, providing faster access and greater durability, although they are more expensive. Optical drives use lasers to read and write data on media like CDs, DVDs, and Blu-ray discs, offering a cost-effective but limited storage option.

Physical storage is also known as RAM it is information that is stored till the Computer is shut off it has a fast access to the information being used at that present time. Other methods would be a hard drive and floppy disk and a USB drive these allow you to save your information to use at a different time and even on different PC. The information is saved even after the Computer is shut down.
