Technovations

By Issie Rabinovitch

Tech products seem to be appearing on the market faster than an Athlon 64 X2 Dual-Core Processor can manipulate data. Some are more for entertainment than for work, but many have features you might find useful. CAmagazine asked technology writer Issie Rabinovitch to test new products and write regular assessments for this column. Issie has been working with CAs in the technology field for years and, in choosing the products, he has your needs in mind. Issie rates each on a scale of one to three stars.

Peer pressure
Business networks used to be peer-to-peer or server-based. With the growing use of devices that attach directly to the network, the dividing line between network categories is blurred. Peer-to-peer networks connect directly to a server and are popular in business and at home as they are inexpensive, flexible and easy to set up. Networks with one or more dedicated servers better address the computing needs of a business but are more expensive and require expertise to set up.

Using printers and disks that connect directly to a switch are an inexpensive way to add some benefitsof a server-based network to a peer-to-peer network. As a result, their availability to network users does not depend on one particular computer as they are never powered down. In a typical peer-to-peer network, if a computer freezes or is turned off, every-thing connected to it and shared on the network becomes unavailable. If you need a file or want to send a print job to the network’s printer, you will be inconvenienced.

To solve these problems, there are the Iomega StorCenter Network Hard Drive 250 GB — an external hard disk with a network port connecting directly to a network — and the Linksys Network Storage Link, a device thatalso connects directly to a network, allowing for a conventional external disk connection to shared files and disk space on the network.

Linksys Network Storage Link
The The NSL is a small device with powerful features. It is smaller than a switch or modem and weighs 5.5 oz. with dimensions of 5.1 x 0.8 x 3.6 inches. It connects to a switch or router by a cable (included with purchase) that has an Ethernet connector at one end and a USB connector at the other. It also has an external power supply.

The NSL has two USB ports. USB hard drives can be connected to both ports with one of the ports accommodating a USB flash drive or memory key. Drives that are connected to NSL become the functional equivalent of network drives. They are accessible from any computer on the network, although access can be controlled by password. The NSL can also be set up so that drives are accessible from the Internet and can be made public or restricted to authorized users.

The NSL is an attractive product for several reasons: there is a greater choice among USB drives than network drives, they are cheaper and the combined price of this unit and a USB drive is less than a network drive of the same size. Finally, if you already own USB drives but wish they were network drives, buying a NSL or two makes a lot of sense.

Iomega StorCenter Network Hard Drive 250 GB
While the Iomega Network drive looks just like the Iomega USB drive reviewed in the April issue, appearances are deceiving. The Iomega Network drive’s rear panel shows an Ethernet port for a direct network connection. Connecting the cable to the drive and to a router or a switch takes only a minute, making its 250 GB available to all network users. Conventional USB hard drives or flash drives can also be connected to the two USB ports if more storage is required on the network. The software is included and consists of the same Automatic Backup Pro application previously reviewed.

This network drive is not as fast as internal drives but does a good job when working with word processing, spreadsheets and image files. However, better choices for demanding applications, such as a database with more than a few concurrent users, exist.

Iomega has network drives as small as 160 GB and as big as 1 TB. (A TB is a terabyte or 1,000 gigabytes.) Price: $350
