What's in Storage Just when you were getting used to gigabytes, now there are even bigger ways to store and manage your data.

All those business bits and bytes add up, and finding ways to store them can be a constant challenge. Most entrepreneurs will turn to a combination of storage technologies ranging from USB flash drives to full-on network storage systems. We used to talk about storage mainly in gigabytes (GB), but we've now magnified that into terabytes (TB). The onward march of storage technology is turning in bigger storage, more advanced features and lower prices for growing businesses.

The Dell PowerVault MD3000i iSCSI SAN is a Storage Area Network (SAN) system with some muscle to handle more sophisticated storage needs while still working with your existing Ethernet network. Dell's iSCSI solution is a more affordable option than the Fibre Channel systems that have dominated the SAN market. With expandability up to 45TB, it gives a business plenty of room to grow. The $1,400 Netgear ReadyNAS NV+ RND4210 is a 2TB Network-Attached Storage (NAS) solution tucked into a compact appliance. It's stuffed with user-friendly features like printer sharing, built-in backup, system monitoring and automatic alerts.

For a single computer or a very small workgroup backup, the $550 2TB Western Digital My Book Mirror Edition is ready to keep two copies of all your data. The two hard drives can be set to mirror the data using RAID 1 technology to protect your information should one hard drive fail. In a similar vein, the $300 Newer-Tech Guardian MAXimus 500GB has both Firewire and USB connections and two 500GB drives that mirror each other. It's available in sizes up to 1TB (with two 1TB drives).
