Storage Guide

For security and peace of mind, it is always advisable to archive or backup your image files to an external hard disk, optical media or the Cloud online storage facility. Computer hard disks can often fail or can become corrupted. With many digital cameras and digital SLR cameras having 20 megapixels or more, image file sizes have grown rapidly and now require large storage solutions.

DVDs are a cheap and easy way to back up large amounts of image files and current DVDs can hold approximately 4.7 gb of data in both DVD-R and DVR+R formats.

CDs can only hold around 650mb or 700mb or data and have largely been replaced by DVDs which offer much higher capacities at almost the same cost. All DVD drives can read DVDs & CDs. The cost of internal and external DVD writers has fallen dramatically over the years and nearly all DVD writers are capable of writing or burning to DVD-R and DVD+R discs as well as rewritable DVD-RW and DVD+RW discs. The DVD is slowly being replaced by Blu Ray which can store upto 25gb on a single side and 50gb on a double sided disc.

External hard disks are an excellent choice for storing image files. Most external hard disks can be connected to a computer using USB2, USB3 or firewire connections offering high speed data transfer. External hard disks for home or office use can now be found at very low prices ranging in capacity from 500 gb to 5 terabytes or more. These drives are ideal for backing up thousands of images and large videos but it is always advisable to keep two backups of important images and data with one backup kept off-site.

Small pocket size external hard disks use 2.5" disks which are normally used in laptops while the physically larger external drives use 3.5" SATA or EIDE hard drives that are more commonly used in your average desktop computer. Network storage devices are also proving to be more popular with the explosion in home broadband wireless networks.




Cloud online storage services have grown rapidly in recent years with many companies offering large terabytes of storage for a monthly fee. The advantages include having your images stored off-site and having them available for download from anywhere in the world where there is an internet connection. Unfortunately, many internet connections are still fairly slow around the world and downloading large images can be a slow and frustrating process.
