Computer Considerations

Selecting a computer to handle digital workflow is an important decision, especially when image editing software consumes so much of the computer’s resources to accomplish tasks quickly and efficiently. There are a few important considerations as you decide on which computer is right for you.

 

CPU

A computer’s CPU is the engine that drives the speed and efficiency of the entire operating system as well as installed software. Modern personal computers and laptops offer options for having multiple processors in the computer. A computer with a quad processor, for example, offers four processors to handle functions and tasks quickly when compared to a single processor.

 

The speed of the processor is stated in GHz. A 2.5 GHz processor is faster than a 1.8 GHz.

 

Processors are also manufactured that will handle certain tasks more efficiently as well. For example, some processors handle gaming applications better than others.

 

Computer Storage

Computer memory expresses the amount of space available for storage of installed software and saved data files. This space is separate from other memory specifications such as RAM, which is used to run active processes.

 

RAM

Also known as Random Access Memory, RAM refers to the memory allocated for handling temporary processes required to run software applications and calculations. Increased RAM increases the efficiency of processes and tasks.

 

SSD

Also known as a Solid State Drive, the introduction of SSDs has added a new level of speed and protection for files and processes that photographers require for working with images. SSDs can be found in desktop and laptop computers as well as external storage devices.

 

Benefits include:

· Longer life span over non-SSD media because there is no spinning disk

· Less time required for the computer to boot up

· Files open and processes are faster with SSD drives

· Fast read and write times

· External SSDs are less susceptible to accidental bumps

 

 

Archiving Digital Files

Protection of image files is an important consideration. As technology changes, new devices are developed, and existing devices improve or seemingly disappear. It is important to keep an eye on emerging technologies and those which are disappearing. The time spent editing and working on images is reason enough for you to protect your work. The following are considerations for archiving your valuable files.

 

Begin by transferring files from your camera storage media onto multiple computer storage devices using multiple storage media types.

 

Portable External Hard Drive—Very popular for storage of large numbers of files. They are relatively inexpensive and easy to store and retrieve when full. They are somewhat delicate and easily damaged if dropped or mishandled. SSD portable drives may be less fragile and provide added longevity.

 

External Hard Drives— These larger capacity external hard drives provide an excellent way of storing files. These systems utilize multiple hard drives which can be set up in a RAID Array to store data on two separate hard drives simultaneously. This process is called mirroring and provides added security of having data on two drives in the event one of them fails.

 

The use of a RAID array along with cloud storage provides additional protection in the event of drive failure and allows for easy offsite storage options.

 

Cloud Storage—Off-site storage cloud servers offer storage of digital files that can be uploaded and accessed through an internet connection.  While uploading and file retrieval is not as fast as other storage options, cloud storage adds a layer of safety by storing files in a location separate from hard storage devices which may be susceptible to theft, fire, or other damage.

 

Best Practices for Digital Storage

Redundancy is the best practice for storing valuable digital files. Because of the low cost of digital storage, photographers should utilize a workflow the includes the creation of duplicate files that are stored on two or more media types and stored at two or more locations.

 

The fact that data storage technology changes and can become obsolete is another reason for using multiple storage devices. Items such as floppy disks and zip drives are obsolete and even CDs and DVDs seem to have disappeared. 

 

No single method of file storage should be used without an additional backup of those files on other media. This offers a layer of protection for your files in the event one of the storage methods becomes damaged or inaccessible. It is also a good idea to place these backups at a separate location in the event of catastrophic damage to one of the storage venues.
