             When collecting digital content, it is essential to decide how you are going to store the data. There are many available options such as hard disk drives as suggested by Tom Coughlin in Forbes Magazine. Hard disk drives are recommended because they can be continually connected to the storage network to allow for the information to be easily retrievable. Hard disk drives allow for digital collections to store more content in their collections. When considering the hard ware you will need to store your digital data it is important to consider how much data you will have and how it can be accessed. Using a hard disk drive is efficient for a collection that is large and needs to be rapidly accessible.
 
             The pros of hard disk drives are mass storage and how they can be connected to the network at all times to allow for all the information to be accessible all of the time. Another benefit of using hard disk drives is how they can be combined with flash memory to enhance the overall system performance. However, the cons of using a hard disk drive is that they do wear out between three to five years. Because the device is continuously running, decay is caused by thermal erasure. According to Coughlin's article a open source software and commodity component company, BlackBlaze, created a 180 TB hard disk drive system for $9, 300 which breaks down to $51.67 per TB and 5 cents per GB.
