Digital single lens reflex (DSLR) cameras are popular, but why?
What we like Abundant storage capacity Relatively cheap Mostly stable
What we don’t like Can fail and cost everything for you Can be lost in disaster
Magnetic storage refers to any storage that involves a hard disk. While your computer probably has a hard disk, you can also buy portable hard disks that are plugged into your computer. You can add additional hard drives to a desktop computer. Magnetic storage is a stable storage. It also contains a lot of data - a 250 GB hard disk contains about 44,000 12MP JPG images or 14,500 12MP images. If you are using an external hard drive, you will have to pay a little extra for a hard disk that comes with a cooling fan. The discs are in a closed place and can get hot. The disadvantage of external hard drives is that if a fire or other accident occurs in your home or office, the drive can be damaged or destroyed. Some people have decided to store the second drive in an extra safe place.
What we like Easy to create and store Cheap Worth sharing
What we don’t like Easily lost or damaged Limited power CD, DVD and Blu-ray all kinds of optical storage.
These are available in different R (read only) and RW (rewritable) formats. And W discs can be rewritten, and using disks is safer and cheaper, as they can only burn once and there is no risk of the discs being accidentally overwritten. On average, R disks are more stable than RW discs in the long run.
The CDs contain 700MB of data and can hold about 12 12-megapixel JPEG images or 40 12-megapixel RAW images. DVDs contain 4.7 GB of data, which is six times more than a CD. These are called single-layer DVDs. Double-layer DVDs have 8.5 GB of data, but are currently less compatible with computers. Blu-ray discs can hold up to 25GB of data on single layer discs and about 50GB on dual layer discs. Most disc-burning programs come with a verification option which, although it prolongs the process of disc burning, needs to be followed. During verification, the program checks that the information burned on the CD or DVD is the same as the data on the computer's hard drive.
Errors are not heard when burning CDs or DVDs and other programs are used during the burning process, but these may be particularly common, so turn off all other programs when burning CDs or DVDs and use verification to avoid errors. The big problem with optical storage is that many computers (especially laptops) are now being sold without CD / DVD drives. You will need to purchase an external DVD drive to continue using DVDs and CDs after upgrading your next computer. Again, if disasters hit your disk storage, they can be damaged or destroyed.
What we like Accessible anywhere Changing the size options Cannot be lost or destroyed (physically whatever) What we don’t like Your files do not have physical control Only accessible via an Internet connection Computer Files is the newest way to automatically save photos and important documents uploaded to the cloud, and it's a convenient way to create backups.
These services can be programmed to automatically upload a file to the Internet. Popular cloud services like Dropbox, Google Drive, Microsoft OneDrive, and Apple iCloud can be integrated into almost any device and computer.
Many include a certain amount of free storage space and you can pay for more storage if needed. Online backup services like Carbonite and Code42 CrashPlan are convenient way to backup all the files on your computer to online storage.
These services charge a monthly or annual fee but are convenient in the long run. They automatically update any files you change, and even after deleting most store files from your computer (accidentally or intentionally)
Cloud storage is still a new technology. Not only is it important to keep a subscription current, it's also important to keep track of the files you're storing. Use a reputable company that you can trust that you can trust. There is nothing worse than handing over your valuable photographs to a business that lasts for a year or two. When using cloud storage, think about what might happen to your family. They may want to access your photographs after your death, so figure out a way to let them know where you store the files and how to access them, including usernames and passwords.

What we like Cheap Easy to share Portable What we don’t like Easily lost or damaged Limited power Flash drives are extremely convenient way to store and transport files and they hold more files than ever before. Their small size makes them attractive for storing and sharing many images together. However, they are not the best option as a long term storage solution as they can be easily damaged or lost and the data they have is very easy to delete.
