Start by pricing a multi-drive hard drive with two bays

The most basic type for a multi-drive hard-drive tower is one with two bays. These typically cost less than other types and you can upgrade almost any hard drive to one with two bays without the need for a technician. You can find most two-bay hard drives in the hundred-dollar price range, though some companies do charge more.

I recommend: LTG Technology sells two-bay hard drives ranging from $120 to $420. It offers FAQs and other useful information on its website, including articles on hard disk upgrades. ThinkComputers provides reviews and articles on selecting multi-drive hard drives. It also provides links to vendors selling the reviewed products.

Compare prices for hard-drive towers for storage

Whether you need to increase your the storage capacity for your computer or you discover that a two-bay hard drive satisfy your needs, you can look into other options like hard drives with four bays or ones designed to operate as storage farms. Prices on these range from $130 to $300.

I recommend: Addonics Technologies provides information on how to use its mini-storage tower as a storage farm. Its storage towers are smaller and weigh less than other kinds of multi-drive storage devices. They cost between $100 and $300. Kintronics provides information on the features, server selection and the specifications for its drive towers. It builds to your requirements, so prices vary.

Consider upgrading to standalone multi-drive hard-drive Towers

With a standalone tower, you won't tie up your personal computer (PC) when you need to use it. Many of these multi-drive hard-drive towers are designed as duplicators, which can be useful for musicians making CDs. Depending on the number of drives, these can range from $160 to $7,000.

I recommend: Princeton Disc provides detailed descriptions for its duplication towers. Most of its towers are standalone towers. CD Copy Online.com provides a brief write up to help you determine which duplicator to buy. You can also search its site for a multiple hard-drive tower that meets your search criteria.

Simply put, a drive tower is an enclosure built to store computer drives. Mostly, these are hard disk drives, though they can be CD or DVD drives or other types of drives as well.

In addition to mounting hardware, a drive tower typically contains a power supply, cooling fan and connecting cables, so you can insert a drive right out of the box it came in.

Benefits of multi-drive storage devices include:

1. Multi-drive, hard-drive towers use less power than individual hard drives;

2. You can expand the drives, since most of them operate when only some of the bays are full, allowing you to add drives as you have need;

3. And the drives offer an inexpensive and easy backup solution.

Choose from several multiple-drive network attached storage towers for home or small business at Netgear. Take advantage of an expandable media-storage device that also functions as a home or small business network server from Hewlett-Packard.

Store and backup more data with hard drive towers

Some people call multi-drive, hard-drive towers RAID towers, which stands for Redundant Array of Independent Disks. This sometimes means the drives write the same data to more than one drive to guard against failure of a single drive. Hard-drive towers can often support several types of hard-disk technology, though many people prefer Serial Advanced Technology Attachment (SATA) drives, since they are faster and you can remove or add to the drive when the network is running.

I recommend: Choose from several brands and styles of multi-drive, computer storage devices from the storage experts at Addonics Technologies. Find inexpensive SATA and RAID towers at CalOptic.

Put your network storage in one place with a multi-drive storage device

Larger corporate networks need devices with room for more hard drives and other options that support the large amount of power consumption and cooling needs these larger quantities of hard drives require.

I recommend: Find several multi-drive devices for storing data in various price ranges, including large full-featured server chassis and rackmount enclosures, from costcentral. Choose large multiple-bay drive enclosure models for your backup and network needs at CTI Computech International.

Quickly produce CDs and DVDs with duplication towers

Duplication towers are able to copy several CDs or DVDs at one time, because they contain several CD or DVD burner drives. Some of these devices grow as your needs grow, allowing you to add more drives into open bays as you need them.

I recommend: Choose from a number of CD/DVD multi-drive towers built for the purpose of disc duplication at Princeton Disc. Select from a wide variety of CD and DVD duplication towers and automated duplicators at SuperMediaStore.com, which offers weekly hardware deals.

Tips & Tactics

Helpful advice for making the most of this Guide

• •  Multi-drive hard drives can serve as one kind of backup to guard your data, but should not be your only backup. In case of flood, fire or theft, all of your data can be lost if you don't also have an off-site backup option.

Multi-drive hard drives can serve to add storage to your network or become extra storage for a single computer. Some have features that allow them to serve as automatic backup to protect your data, and others expand your storage capacity to hold movies or music or other large file libraries.

Product reviews compare and contrast many features and benefits of the specific drive tower they are reviewing. Multi-drive hard drive towers advice and ratings can discuss many features, including:

1. The number of bays included in the drive tower, which corresponds to the number of drives it will accept.

2. The function of the tower, so you know whether or not the multiple bays serve as automatic backups of the other drives.

3. The connection of the drive enclosure to the computer or network and whether it will attach directly to a router.

Power supply

A tower drive needs its own power supply. The power supply is the unit that provides for electrical power to the hardware. Specific kinds of IT power supplies provide the juice for drives hooking up to a network.

I recommend: See more on power supplies, including aspects of getting power to drive towers and other hardware, at How Stuff Works.

Network server

Multi drive towers are often hooked up to a network server. A network server is a powerful computer unit that relays data and handles migration tasks within the network.

I recommend: See more on network servers and other terms for IT setups at this McGraw-Hill Online Learning Center.

Redundant Array of Independent Disks or RAID towers

RAID systems allow for parallel drive use. A hardware RAID device presents the RAID arrays as a single drive. External RAID systems operate with a single controller and appear as a single disk within an overall IT structure and are popular for housing a lot of data 'under one roof.'

I recommend: See much more on how RAID works at RedHat Documentation.

Drive expansion

Multi drive hard drive towers, like other hard drive hardware components, allow for drive expansion. Drive expansion is the idea of fitting other components into an existing structure for more power or data handling.

I recommend: See tips on drive expansion at Tech Support Forums.

CD/DVD duplication towers

Some drive towers operate as CD and DVD burning devices. This kind of resource can be critical for a business trying to distribute data in a CD or DVD format.

I recommend: See more on CD/DVD duplication towers at AfterDawn.com.

SATA

SATA or Serial Advanced Technology Attachment refers to a traditional process of linking up hardware with cable 'pin' attachments for serial hookup. Lots of drives still carry conventional SATA connectivity.
