Serial ATA150, set up in a software RAID0. |

My hdparm gives me: |

Timing cached reads: 2776 MB in 2.00 seconds = 1387.91 MB/sec |

Timing buffered disk reads: 398 MB in 3.00 seconds = 132.48 MB/sec |

For redundancy I use backups to a Seagate Barracuda 7200.8 ST3300831AS |
| 16 |
300GB 7200 RPM Serial ATA150 Hard Drive. |
