Howdy,
I'm wanting to get a hard drive that is pretty good size. I'm looking for
about 1 to 2TBs or so. Thing is, a lot of them seem to be 5900 or even 5400
rpm drives. I realize that the data on there is packed pretty tight so I
want to ask a few people that may have one or more of these things a few
questions. Are they as fast as a slower RPM drive? Would they be fast
enough to play HD videos and such? I have quite a few 1080 HD videos. I
don't want the drive to cause issues.
Ignoring your question somewhat, since the hdparm test won't actually
get you 'effective' throughput, only 'ideal'.
( (4.4*1024*1024*1024) / (120*60) ) / 1024
640.796
So a 4.4GiB movie that lasts 2 hours would require a sustained drive
throughput of 640KiB/s - which is pretty achievable.
My experience says that it doesn't matter how slow a drive you use,
provided that you beef up mplayer's cache size and minimum cache
threshold, since my laptop has a slow drive that likes to power down,
but loads of RAM.
grep cache /etc/mplayer/mplayer.conf
# cache settings
# Use 8MB input cache by default.
cache = 131072
# Prefill 20% of the cache before starting playback.
cache-min = 20.0
# Prefill 50% of the cache before restarting playback after the cache emptied.
cache-seek-min = 50
I have the same here too. Like minds maybe? o_O
