Though the name may evoke images of marauding corporate types, the RAID controller isn't used for violent video games. RAID or Redundant Arrays of Inexpensive Disks technology is for handling various disks or drives and presenting them to a user.

Business operators use diverse types of RAID controllers and RAID controller card models to deal with data flow in situations like the following:

1. To link up hard drives to present them over a network and through the interface of an operating system to users.

2. For upgrades of existing systems, where a ported or USB RAID controller provides better connectivity for IT systems.

3. For general purposes of enhancing data storage and backup across an entire business network or system.

Action Steps
The best contacts and resources to help you get it done

Get SCSI RAID controllers

SCSI technology has long been popular with many tech buyers. SCSI or Small Computer System Interface links up multiple drives to an IT system. Though very effective (and traditionally used), SCSI RAID controllers often come at premium prices.

I recommend: Get Adaptec SCSI RAID controller models. For deals on more RAID controller models using SCSI, browse prices at DiscounTechnology to see if you can find something in your price range.

Get computer RAID controllers utilizing iSCSI

With the emergence of web-oriented and wireless technology, vendors have found out how to migrate SCSI to the Internet. With new iSCSI connectivity, a TCP/IP connection replaces the old manual methods. Look for RAID controllers using iSCSI for state of the art disk array solutions.

I recommend: Find iSCSI RAID controllers, browse specs, check out prices and make deals at AuraGen Technologies. You can find more iSCSI RAID models, including multi-porting types, at StoreHouse Technologies.

Get other RAID controller types

Online vendors of RAID technology also sell other options including IDE RAID controller models, IDE/ATA types, and other options. The IDE or Integrated Drive Electronics technology can be cheaper than SCSI, and IDE/ATA and SATA RAID controllers can get you your desired goals more efficiently, depending on your system.

I recommend: Find Serial ATA or "SATA" RAID controller models at 3ware. Look for IDE RAID models at Directron.com, where you can see product prices up front, check for specs and buy RAID controllers using the shopping cart technology on site.

Tips & Tactics

Helpful advice for making the most of this Guide

• •  Match drives and connectivity. Nobody is an expert on RAID, so to make it easier, don't try to re-invent the wheel every time you buy.
• •  If your controller comes with a RAID controller driver to help with installation, keep it on hand. Manuals and accessories can help you determine which technology fits your existing system. When it comes to implementing disk controls, compatibility is key.
