RAID 5 users anxiously awaiting the debut of 2 TB drives to help build massive storage array’s may want to think twice before taking the plunge. An in-depth look into the underlying problems with massive storage RAID5 configurations suggests that s a single drive as redundancy might not cut it anymore. SATA drives carry a specified unrecoverable read rate of 10^14. This might sound like a huge number, but it basically tells us that any array in excess of 11.37 TB will contain at least one unrecoverable read. In the case of a RAID 5 rebuild, this can be catastrophic.
Hit the jump to learn why RAID 6 won't help you, and to see what the future holds.
My question regards backing up games using tools like ImgBurn and Daemon Tools. I use ImgBurn to create the ISO from a disk and Daemon Tools to mount the ISO. But for some reason, with half of my games I get the message “Please insert the original disk” when I try to run the game from the ISO. My method works with older games but not newer ones. I understand that some of these games might have some kind of protection on them preventing me from running them off an ISO, but I paid for these games and I should be able to create backups of them. Do you know how I can back up my games so they actually work?

The Iomega Zip drive once was synonymous with consumer-friendly data backup. Seagate aims to change that with a huge makeover of its FreeAgent line of external hard disks and a companion advertising campaign designed to tug at the heartstrings of today's increasingly media-consuming families.
Announced Monday, Seagate's new FreeAgent models include the portable FreeAgent|Go and the desktop FreeAgent|Desk (both available in separate editions for Windows PCs and Macs) as well as the high-performance desktop FreeAgent|XTreme for Windows PCs. The goal of the new line of products is to "Save, Share. Simplify."

Power users who have dreamed of outfitting their portable backup solution in a RAID 0 array can now do so thanks to Addonics' new Portable Dual Drive RAID enclosure (AE25RDESU). Nervous Nellies are covered too, with RAID 1 providing a backup for your backup. The handheld device accepts up to two 2.5-inch SATA drives inside its "heat resistant aluminum" chassis, or pick up the optional SATA-CF hard disk adapter and install up to four CompactFlash cards. Other notable features include:
Easy installation and removal of hard drive
USB 2.0/1.1 and eSATA support
RAID configuration with DIP switch or GUI configuration
Supports RAID 0, RAID 1, JBOD, BIG (Concatenation), SAFE50, SAFE33, or GUI mod using built-in hardware RAID
Can be powered by USB port
For backup duties Addonics throws in DriveClone software and the device itself includes a backup button the company claims "can be configured to provide the convenience of one button backup of any critical files or folders."
Pricing has been set to $100 and can be purchased now.
