 The Cloud Storage Vs Local Storage

The Cloud Storage: anywhere, any time, as long as you have Internet

It has become fixed in how we store, access, and share files, photos, videos, and more. What's not to like? Cloud storage, you can access your file anywhere from any device. They practically act as remote backups, for those cases when you lose, or delete, your local copy.

However, you do require an Internet connection for advance activities. You can edit, view, or do anything else with local copies stored on your device, but you need an Internet connection to upload, sync, and download any file. It's not always a problem but not all locations are created with great internet coverage. Should you have an Internet connection, you still have to be careful of bandwidth usage, downloading large media files all at once may not be appropreate. Although you could stream them but that depends on avaliability of Internet connection.

Another drawback is the question of security and privacy benefits that these cloud services offer. A big issue is the ability of third parties gaining access to your data or use your Internet traffic, with or without the knowledge of service providers. Anything you put out on the Internet; cloud storage, social networking, anything, is always open to theft.

 

Local Storage: fast and secure and fragile

Having the files and work you need right at your fingertips, almost literally, is a huge convenience. An advantage with local Storage compared to Clound storage is you dont have to worry about download or upload times, you are instanly able to watch videos without lag or buffering, also with the ability to listen to your tunes endlessly. To add, there is no need to worry about unwanted eyes and hands gainning access to your data. As long you keep contenet or source off the Internet, you have very little to worry about of the files. The security and privacy of your data is as strong as you allow it.
However you are limited to the amount of data you can store at a single time. The highest capacity of internal storage commonly found on smartphones are capped at 64 GB, the most common high capacity microSD card is 128 GB, but not all smartphones can even support that yet. You can expand your available storage with a useful combination of an external hard drive and a USB on-the-go (OTG) cable but is inconvenient. You end up, trying to decide which files you want to always be with you and files you would swap around with your computer or hard drive. Plus its not an exactly fast or easy way for sharing photos and files with others.

 

Apropriate storage devices 

·         Store a high definition movie -  DVD, BLU-RAY

·         Distribute some software that you’ve written - CD (inc. CD-R, CD-RW), DVD

·         Transfer GCSE Media coursework between home and school - USB Memory stick

·         Storage area on a college network - HDD

 

Factors that should be considered when selecting a suitable storage medium to use in a given situation:

• Capacity
• Speed
• Durability 
• Portability 
• Reliability

An example device that makes use of solid state memory storage would be a Memory Stick or USB Memory Card.

 

One benefit of using a magnetic storage device (a HDD) compared to a solid state device (SSD) for storing files on a network is the capacity, HDD has a much higher capacity than a SDD.
