Why RAID 5 Stops Working In 2009 803

Posted by kdawson from the back-'em-up-rawhide dept.
Lally Singh recommends a ZDNet piece predicting the imminent demise of RAID 5, noting that increasing storage and non-decreasing probability of disk failure will collide in a year or so. This reader adds, "Apparently, RAID 6 isn't far behind. I'll keep the ZFS plug short. Go ZFS. There, that was it." "Disk drive capacities double every 18-24 months. We have 1 TB drives now, and in 2009 we'll have 2 TB drives. With a 7-drive RAID 5 disk failure, you'll have 6 remaining 2 TB drives. As the RAID controller is busily reading through those 6 disks to reconstruct the data from the failed drive, it is almost certain it will see an [unrecoverable read error]. So the read fails ... The message 'we can't read this RAID volume' travels up the chain of command until an error message is presented on the screen. 12 TB of your carefully protected — you thought! — data is gone. Oh, you didn't back it up to tape? Bummer!"

IE The Great Microsoft Blunder? 643

Posted by ScuttleMonkey from the not-a-shining-example-of-engineering dept.
JordanL writes "Hot on the heels of the beta rollouts of IE 7, comes an editorial from John Dvorak declaring IE the biggest mistake Microsoft has ever made. From the article: 'All the work that has to go into keeping the browser afloat is time that could have been better spent on making Vista work as first advertised [...] If you were to put together a comprehensive profit-and-loss statement for IE, there would be a zero in the profits column and billions in the losses column--billions.'"
