HDD and SSD background
A hard disk drive is a computer data storage device use for storing and retrieving digital information using rapidly rotating disks coated with magnetic material. An HDD retains its data even when powered off. Data is read in a random-access manner; the meaning individual blocks of data can be stored or retrieved in any order rather than sequentially. An HDD consists of one or more rigid rapidly rotating disks with magnetic heads arranged on a moving actuator arm to read and write data to the surfaces.
A solid state drive is a data storage device using integrated circuit assemblies as memory to store data persistently. SSD technology uses electronic interfaces compatible with traditional block input/output hard disk drives, thus permitting simple replacement in common applications. SSDs have no moving mechanical components. This distinguishes them from traditional electromechanical magnetic disks such as hard disk drives or floppy disks, which contain spinning disks and movable read/write heads. Compared with electromechanical disks, SSDs are typically more resistant to physical shock, run silently, have lower access time, and less latency.
In my opinion, a solid state drive structure is very simple, but compare with mechanical hard disk is not in the same level. SSD can make computer performance speed up. It look like your computer has one more CPU. A hard disk drive is cheaper and it always has 500GB – 1TB storage. How should we choose? I think it depend on how to use your computer. If you want your computer performance faster, you should use SSD. If you feel your computer performance is enough for you and you want more storage, you can use HHD.

HDD has higher latency because HDD is use spinning...

...dvantages and disadvantages
Advantages of SSD: SSD is lighter than HDD, the size always is 1.8- inch and weight 20-30 grams, Low noise at work, has not too many mechanical parts so just have a little heat, fast heat dissipation.
Disadvantage of SSD: the price is very expensive and the capacity smaller than HDD.
My experience with SSD
If you want to buy a new notebook for desktop replacement, and you have choose to install SSD or HDD. At the same time you still using portable hard disk. You may have a question do you need to install SSD or using the traditional hard disk? If you choose to install SSD, what size is good fit for you?
My suggestion is that if you using a portable hard disk, you can go to install 128 GB SSD. Just remember the SSD just for your software, another data save to your portable Hard disk. It will be upgrading your computer efficiency.
The two systems I have chosen to replace my old computers are the HP All-in-One Computer ProOne 400 G3 and ASUS ZenBook 14” Laptop. For the software, I have chosen Office 365 Business, Intuit QuickBooks, and Bitdefender Total Security 2018. The complement the two systems, I have chosen the 2.5’’ Ultra Slim 320 GB Portable External Hard
decision that is very important if you decide to buy a computer for work or home
The next topic that is discussed is the topic of visual representations made by the computer such as pictures, so it speaks of how images are transferred into binary code and then reformed to create a rendering of the image. The resolution of this image is based on how many pixels the display has the more pixels the higher the resolution. The next point that of which the chapter speaks about is what happens to deleted data files. After data has been deleted the users think that it is gone. However, when data is deleted the blocks it is comprised of that are no longer part of any files are added to a “pool” of available disk blocks. This makes them accessible, if the binary code that formed the data was zeroed insead then they couldn’t be accessible. the data of the used blocks are saved to add these blocks to another file where to be reinstated into the computer in a data file. These blocks can be seen by anyone who has this knowledge, and these blocks can contain sensitive personal information that was deleted for a reason such as: account usernames, account passwords, bank account numbers, and
Another feature that is a first in the console industry is Xbox’s internal 8-Gigabyte (Gb) Hard-Drive or Hard Disk Drive (Hdd). This contributes too much of Xbox’s weight, but gives many features. With this you don’t have a need for a memory card to save your game files, you save them right to the hard-drive. This is a very nice feature on the Xbox, because it saves you money.
Due to the volatile nature of the computer memory, information might be lost or overwritten over time. The chip in the random access memory helps the computer to run its programs more efficiently by pulling the data from the RAM. However, every time a machine is switched on, some data stored in the RAM is lost. Whereas the data stored on the hard drive is known as persistent data, the RAM is known as volatile memory. The RAM is constantly swapping the rarely used data that is the hard drive to create space for new information. Therefore, the longer the investigators wait, the more likely they will lose the incriminating data since the computer is not indefinitely persistent. It is fortunate that the investigators have found ways to preserve the evidence without necessarily switching on the computer. The contents are used in courts as the lawyers can use them as evidence for criminal activity.
The database administrators machine will be a little tricky as it is already considered to have malware. Good malware will want to stay on the computer and be looking out for forensic type activities. The first part is to assess from the above steps is if the machine is able to be shut down safely and not lose any data. Whatever data that can be attained should be documented and considered before moving forward.

In recent years, optical disk drive has become one of major data storage devices in auxiliary memory devices and AV systems. The reasons for this popularity are its short access time compared with that of magnetic tape drive, exchangeability of disks, and almost unlimited lifetime [New Fine Seek Control for Optical Disk Drives]
The solid state drive is a very unique piece of technology that was created in the late 1980’s and early 1990’s. It is a storage device that incorporates solid-state memory and emulates a hard disk drive to store data. Solid state drives use interfaces such as USB and PCI express. It is very light, quiet and uses very little power to function, thus making it a very important piece in a modern day computer. As time goes by, there are more and more solid state drives that are found in laptops and even mobile devices as they are relativity smaller than hard disk drives and are much faster. Also if you accidently drop your laptop or mobile device from a decent height (five feet) while it’s processing, then you will greater chances of retrieving your data than a hard disk drive. But there are indeed some downsides to the solid state drive, not many but one that makes it hard to come by, the cost. The cost of these small, fast, crazy pieces cost roughly 3$/gigabyte to 0.15$/gigabyte depending on the model, brand, speed and size of course. Compared to other storage devices, these are the highest possible prices that you can ask for, with reason of course, these things are far too fast
We put all of the data onto the platters. They are inside of the hard
The first thing to do is to research what kind of computer you want. If you
On the other hand, if you'd like to use your cloud storage for files that are hundreds of megabytes or even gigabytes in size, it's quite troublesome to download that huge file and share it to others. They may have very slow connection, which makes it quite impractical to download such huge files. You'll be better off burning those files onto a DVD or copy them to a portable hard drive or even USB flash drives. From here on, we'll just have to wait and see. Who knows? As internet connections become faster and faster and as more companies offer cloud storage service, we may see huge improvements in the future.
The invention of computers has made a huge change in human civilization and society, by changing the way people think. Computers replaced jobs and tedious repetitive thoughts that were done by human originally. People became more and more reliant on computers, and thus, computers became essential to our lives. Computers can manufacture products quickly, and eliminate possible human errors. As technology progresses, new ideas have been brought into computer to make them perform more efficiently. Also, scientists and engineers tend to make things “smaller”, so we can enjoy the benefits from electronic devices anywhere and anytime. Therefore, size and efficiency are two main points for consumers. Desktop computer and laptop computer are representatives for each of these concepts. Although desktops and laptops come from the same origin, they are different in many ways.
A storage device is the system where your computer stores and retrieves your data. Storage devices can be a hard disk drive, DVD, CD drives, Blu-Ray drives or flash drives. A computer can retrieve the data by being “commanded” to retrieve it from the storage area and retrieve it to your RAM. The RAM of the computer is your temporary memory where your data is inputted, and then processed and stored onto a storage device for permanent placement.
