An individual won't last that long, they will wear out long before then (unless they are Doctor Who), but for the population as a whole, in that '˜high reliability' portion of There are two reasons to use RAID. 1) Speed - Since a hard drive is a physical device, it can only transmit data so fast. This is a nested or hybrid RAID configuration. my review here However, your math is incorrect.
Moreover, the more disks in the array the worse it gets. Hp Array Configuration Utility User Guide Indeed, in this scenario, if you lose you single 300Gb IDE drive, or you lose one of your two 150Gb RAID 0 drives, then you lose *all* your data, don't you? The drive spins at a certain speed, and the drive head moves back and forth to access the data.
How does one tell that both drives are getting the data such> that there is backup if one disk fails?Well it would seem that what you want to do is simulate
The parity data are not written to a fixed drive, they are spread across all drives, as the drawing below shows.
