Why not a 12TB RAID 6 array for some decent redundancy? Seems silly to place all your faith in that many consumer grade drives during a rebuild.]]>May 7th 2010 9:17AMhttp://www.engadget.com/2010/05/07/homemade-16tb-nas-dwarfs-the-competition-with-insane-build-quali/http://www.engadget.com/2010/05/07/homemade-16tb-nas-dwarfs-the-competition-with-insane-build-quali/May 7th 2010 10:03AMhttp://www.engadget.com/2010/05/07/homemade-16tb-nas-dwarfs-the-competition-with-insane-build-quali/http://www.engadget.com/2010/05/07/homemade-16tb-nas-dwarfs-the-competition-with-insane-build-quali/May 7th 2010 11:10AMhttp://www.engadget.com/2010/05/07/homemade-16tb-nas-dwarfs-the-competition-with-insane-build-quali/http://www.engadget.com/2010/05/07/homemade-16tb-nas-dwarfs-the-competition-with-insane-build-quali/Engadget didn't report anything wrong. The NAS has 12.7TB usable space. The reason it isn't 14TB is because hard drive manufactures count in Terabyte but operating systems use Tebibyte so you loose more than 1TB with a system this large.
Also RAID 5 has redundancy, RAID 6 is basically RAID 5 with 2 parity blocks so you can have up to 2 drives fail and still be able to recover the data. Since you'll loose an additional 2TB of memory it generally isn't worth it in a consumer device. It is highly unlikely that two drives will fail simultaneously, hard drives even consumer ones are phenomenally reliable and this system is just holding media files so the drives wont have very high data access rates.]]>May 7th 2010 11:43AMhttp://www.engadget.com/2010/05/07/homemade-16tb-nas-dwarfs-the-competition-with-insane-build-quali/http://www.engadget.com/2010/05/07/homemade-16tb-nas-dwarfs-the-competition-with-insane-build-quali/
If these drives were don't have there TLER modified or can not be modified (WD started disallowing the setting to be changed on consumer drives to force people to buy the otherwise nearly identical raid versions) it is very likely that drives will often fall out of the raid if any kind of decent hardware raid is used.

Raid is was not created to be a replacement to backups, it was created to either increase performance or to increase the amount of uptime that a system can have.]]>May 7th 2010 12:48PMhttp://www.engadget.com/2010/05/07/homemade-16tb-nas-dwarfs-the-competition-with-insane-build-quali/http://www.engadget.com/2010/05/07/homemade-16tb-nas-dwarfs-the-competition-with-insane-build-quali/
If you scrub your array regularly then you are pretty safe. The UREs will happen when you have parity to recover them with and remap the sectors.

With the right RAID setup though, even if you do encounter a URE during a rebuild you will just lose that one stripe and this will result in most likely a single corrupt file.]]>May 8th 2010 12:23AMhttp://www.engadget.com/2010/05/07/homemade-16tb-nas-dwarfs-the-competition-with-insane-build-quali/http://www.engadget.com/2010/05/07/homemade-16tb-nas-dwarfs-the-competition-with-insane-build-quali/He is to hardware, what geohot is to software (iphone and ps3)]]>May 9th 2010 1:15AMhttp://www.engadget.com/2010/05/07/homemade-16tb-nas-dwarfs-the-competition-with-insane-build-quali/http://www.engadget.com/2010/05/07/homemade-16tb-nas-dwarfs-the-competition-with-insane-build-quali/

It does not matter how high the potential might be, if the circuit is not complete it will not damage any component.

Similar to birds sitting on a high voltage transmission line, but they never get electrocuted.]]>May 7th 2010 5:38AMhttp://www.engadget.com/2010/05/07/homemade-16tb-nas-dwarfs-the-competition-with-insane-build-quali/http://www.engadget.com/2010/05/07/homemade-16tb-nas-dwarfs-the-competition-with-insane-build-quali/May 7th 2010 5:47AMhttp://www.engadget.com/2010/05/07/homemade-16tb-nas-dwarfs-the-competition-with-insane-build-quali/http://www.engadget.com/2010/05/07/homemade-16tb-nas-dwarfs-the-competition-with-insane-build-quali/May 7th 2010 5:48AMhttp://www.engadget.com/2010/05/07/homemade-16tb-nas-dwarfs-the-competition-with-insane-build-quali/http://www.engadget.com/2010/05/07/homemade-16tb-nas-dwarfs-the-competition-with-insane-build-quali/May 7th 2010 5:49AMhttp://www.engadget.com/2010/05/07/homemade-16tb-nas-dwarfs-the-competition-with-insane-build-quali/http://www.engadget.com/2010/05/07/homemade-16tb-nas-dwarfs-the-competition-with-insane-build-quali/May 7th 2010 5:49AMhttp://www.engadget.com/2010/05/07/homemade-16tb-nas-dwarfs-the-competition-with-insane-build-quali/http://www.engadget.com/2010/05/07/homemade-16tb-nas-dwarfs-the-competition-with-insane-build-quali/

I was going to comment the same thing. Back in the day, a case with 50 of those 5.25-inch floppies was a mere 60 MB. Now we're talking 16 TB. In other words, about 300 THOUSAND times the storage in the same size/shape. Amazing stuff...]]>May 7th 2010 7:10AMhttp://www.engadget.com/2010/05/07/homemade-16tb-nas-dwarfs-the-competition-with-insane-build-quali/http://www.engadget.com/2010/05/07/homemade-16tb-nas-dwarfs-the-competition-with-insane-build-quali/May 7th 2010 10:03AMhttp://www.engadget.com/2010/05/07/homemade-16tb-nas-dwarfs-the-competition-with-insane-build-quali/http://www.engadget.com/2010/05/07/homemade-16tb-nas-dwarfs-the-competition-with-insane-build-quali/May 7th 2010 10:40AMhttp://www.engadget.com/2010/05/07/homemade-16tb-nas-dwarfs-the-competition-with-insane-build-quali/http://www.engadget.com/2010/05/07/homemade-16tb-nas-dwarfs-the-competition-with-insane-build-quali/May 7th 2010 3:22PMhttp://www.engadget.com/2010/05/07/homemade-16tb-nas-dwarfs-the-competition-with-insane-build-quali/http://www.engadget.com/2010/05/07/homemade-16tb-nas-dwarfs-the-competition-with-insane-build-quali/
