Like your computer at home, NOLS servers use hard drives, magnetic devices which can store large amounts of data, such a websites, pictures, and ecommerce databases.
NOLS also makes it a point to use some of the best hard drives available. But hard drives, while increasing in reliablility throughout the years, can still fail regardless of the quality of the drive. Unlike your computer at home, NOLS usually stores the same data on several different drives simultaneously, even within the same server. Storing your data on multiple drives helps keep your data safer, because when you upload your website it is automatically copied to other hard drives simultaneously or within seconds. Multiple hard drives can even help increase the speed at which your website is displayed by allowing an idle server to share your website when the main servers are busy or unavailable.
While anyone can purchase a forty gigabyte hard drive at a computer store for about $150, the additional cost of using multiple, industrial grade hard drives can increase the cost of storage space dramatically. |
