Ignoring your question somewhat, since the hdparm test won't actually |
| 13 |
get you 'effective' throughput, only 'ideal'. |

|
| 15 |
( (4.4*1024*1024*1024) / (120*60) ) / 1024 |
| 16 |
640.796 |
| 17 |
|
| 18 |
So a 4.4GiB movie that lasts 2 hours would require a sustained drive |
| 19 |
throughput of 640KiB/s - which is pretty achievable. |

My experience says that it doesn't matter how slow a drive you use, |
| 22 |
provided that you beef up mplayer's cache size and minimum cache |
| 23 |
threshold, since my laptop has a slow drive that likes to power down, |
| 24 |
but loads of RAM. |

# cache settings |
| 28 |
# Use 8MB input cache by default. |
| 29 |
cache = 131072 |
| 30 |
# Prefill 20% of the cache before starting playback. |
| 31 |
cache-min = 20.0 |
| 32 |
# Prefill 50% of the cache before restarting playback after the cache emptied. |
| 33 |
cache-seek-min = 50 |
