Network Attached Storage
Those of us who have used computers for a long time remember the days when floppy diskettes offered the best in computer data storage. Then we graduated to hard drives, CDs, DVDs, flash drives.. and now, network attached storage (NAS).
A NAS is a unit containing one or more hard drives with a network jack. The biggest advantage of a NAS is that it is much less expensive than a server. Instead of spending thousands of dollars for the hardware and software needed to run, say, Window Server, you can spend mere hundreds for one terabyte (that’s 1,024GB, or about 728,000 floppy disks!) of storage capacity. And the device is barely the size of a shoebox.
The key to NAS is its redundancy. NAS writes your data across multiple hard drives using a technology called RAID. The drives are hot-swap, meaning you can replace them while the unit is running. You can also add additional storage capacity simply by sliding in a new drive.
NAS is cross-platform. If you work with both PCs and Macs, you can connect both easily and conveniently to the NAS. You can set up file shares, users and groups on a NAS, just as you would on a server. Some come with built-in backup software. Configuration is done through a simple web interface.
NAS is a terrific server replacement for any small business or home office in need of centralized storage at low cost.
