What is the | This is a new name given to a slightly new technique for |
about? | relocating bad sectors on the disks. Rather than relocate the |
| actual sector, a pointer for the sector number is used. |
| When a bad sector is found, the pointer updates to skip that |
| area - this is done while the drive is reading/writing. If you |
| were to watch the performance of this bad sector, as the |
| performance appears to increase, it could be said the sector |
| was "cured." |

What is journaling and should I use it? | Journaling is where the computer (in the background), logs all |
| disk transactions, such as file open, file write, file read, file |
| close. |
| In the event of volume corruption, this journal is easy for |
| recovery programs to find on the disk and make repairs, |
| based on this file. We recommend journaling (if your OS |
| supports it), in case of such corruption. |

I've heard journaling makes the array run | Journaling only slows down the array by about 2KB/sec. For |
