AFAIK, the only technical difference between a consumer drive and an |
11 |
enterprise one is that the enterprise one doesn't tell lies. Or at |
12 |
least, it isn't supposed to. |

Consumer drives will acknowledge writes before they have hit the |
15 |
platter, even if the cache is disabled on the drive (and some consumer |
16 |
drives do not even allow the cache to be disabled). |

The only scenario this seriously guards against is unexpected power |
19 |
loss, where the drive has told the OS that the data has been written to |
20 |
disk, but it is somewhere in-between (e.g., on cache, but not on the |
21 |
platter) and then the power is disconnected from the unit (specifically, |
22 |
the drive itself). Even an unexpected reboot from the computer won't |
23 |
affect this, unless the computer removes power to the device during |
24 |
early boot (and on x86 systems, that is a virtual impossibility). |

A man who reasons deliberately, manages it better after studying Logic |

than he could before, if he is sincere about it and has common sense. |
