http://www.tomshardware.com/news/RAID-5-Doomed-2009,6525.html]]>Jan 27th 2009 9:57AMhttp://www.engadget.com/2009/01/27/western-digitals-2tb-caviar-green-hard-drive-launches-gets-pre/http://www.engadget.com/2009/01/27/western-digitals-2tb-caviar-green-hard-drive-launches-gets-pre/
SomeJoe7777 is on the right track, but failed to explain it completely.

First consider the soft error rate, the rate at which a bit may be read incorrectly one time, but read correctly most of the time. That number isn't really important other than as a context for what uncorrected read error rate is. The URE rate is the rate at which raw bits passing under the read can't be consistently read AND match what was written. Note that we're talking about the raw bit stream from the media. All HDs for at least 15 years have had advanced ECC encoding on each sector which is capable of recovering from at least one bit (typically several bits) error in the bit stream for that sector. This means that the ECC which is built in to the drive will correct that 10 ^ -14 URE.

The URE applies to the raw bit stream, not to the ECC corrected data coming out of the drive, and the ECC can recover from at least 1 bit error in the bit stream for each (and every) sector on the disk.

Because of that, the size of the drive is essentially irrelevant, it is the sector size and the amount of ECC per sector that is relevant. Because of the sector level ECC, the size of the drive has only a trivial effect on the likelihood of a sector becoming unreadable.

RAID (other than the improperly named RAID 0) offers an additional level of recoverability allowing for a failure of any part of a drive (e.g. one sector, one head, etc.) or a whole drive (e.g. motor, actuator, controller, etc.) to fail and still be able to recover the data.

Likewise, the size of the RAID volume is only a trivial factor in the chances that a RAID volume will be unrecoverable. The number of drives in an RAID 5 or RAID 6 array is many orders of magnitude more significant than the size of the drive or of the volume/array. The more drives, the greater the chance of a failure of one or more drives. The same applies to the seldom/never used RAID 2, 3, or 4 and to a few implementations of RAID 0 + 1 (where the data is striped before it's mirrored)

Because RAID 1 (and RAID 10, aka 1 + 0) mirrors pairs of drives, the number of drives and the size of the array are almost irrelevant. In order to be uncoverable, a RAID 10 array must have a failure the identical portion of the two drives that are mirrored within a short enough timeframe that one failed drive is not repaired/rebuilt before the second failure. That probability does not change significantly by adding more drive pairs to the array.

You can find a 1TB internal for $99

Actually you don't "lose" any space. It only depends on the units you are using for reporting the space on the drive. Does 1 GB = 1,000,000,000 bytes (hard drive manufacturer) or does 1 GB = 1,073,741,824 bytes =2^30 bytes (windows definition reported).

Read the side of any current hard drive and it will explain this as there was a lawsuit ove this years back. Or look up gigabyte on wiki for explaination.]]>Jan 27th 2009 2:39PMhttp://www.engadget.com/2009/01/27/western-digitals-2tb-caviar-green-hard-drive-launches-gets-pre/http://www.engadget.com/2009/01/27/western-digitals-2tb-caviar-green-hard-drive-launches-gets-pre/Jan 27th 2009 8:30AMhttp://www.engadget.com/2009/01/27/western-digitals-2tb-caviar-green-hard-drive-launches-gets-pre/http://www.engadget.com/2009/01/27/western-digitals-2tb-caviar-green-hard-drive-launches-gets-pre/Jan 27th 2009 8:44AMhttp://www.engadget.com/2009/01/27/western-digitals-2tb-caviar-green-hard-drive-launches-gets-pre/http://www.engadget.com/2009/01/27/western-digitals-2tb-caviar-green-hard-drive-launches-gets-pre/Jan 27th 2009 8:49AMhttp://www.engadget.com/2009/01/27/western-digitals-2tb-caviar-green-hard-drive-launches-gets-pre/http://www.engadget.com/2009/01/27/western-digitals-2tb-caviar-green-hard-drive-launches-gets-pre/
