SSDs, I'd currently buy Samsung 850 pro or evo, depending on how they |
| 12 |
are going to be used. |

Well, you get what you pay for. To me, all the hassle a failed disk (or |
| 18 |
other hardware) will give me isn't worth saving a bit of money on it. |
| 19 |
|
| 20 |
Since you got it cheap, why not buy another one and use RAID-1 (and/or |
| 21 |
zfs)? When one fails, shutdown, replace the failed disk, restart --- no |
| 22 |
hassle involved. |

When you get sector errors reported in the log file when accessing the |
| 28 |
disk, the disk has failed (provided that the cabling and power supply |
| 29 |
are ok). This goes for hard disks --- are SSDs any different in that? |
| 30 |
|
| 31 |
Other than that, I don't need any more diagnostics. It would only tell |
| 32 |
me what I already know. |

Without physically destroying it, I won't give any disk out of hand |
| 37 |
which has had my data on it. Unfortunately, that probably means that |
| 38 |
there is no warranty on disks. I only take the duration of the warranty |
| 39 |
as some indicator of what the manufacturer entrusts the disk with, as in |
| 40 |
"5 years may be better than 3". |
| 41 |
|
| 42 |
In practice, hard disks either fail not long after new, or after about 3 |
| 43 |
years, or virtually never because they are replaced for other reasons |
| 44 |
before they fail. SSDs might be different; I don't have much experience |
| 45 |
with them yet. |

Again we must be afraid of speaking of daemons for fear that daemons |
| 50 |
might swallow us. Finally, this fear has become reasonable. |
