Video bitrate for modern harddrives

[tke444]

I am not familiar with everything bitrate so I would like to know what the highest (rough average?) possible bitrate that can be played from a computer hard drive without it getting choppy, sloppy, or melt my computers insides.

Example: Backing up one of my DVD's to my harddrive and playing the movie straight from the Harddrive is around 8000 kbps and is fine all around. I would like to back up a BluRay of a movie to the harddrive and then play it from there. So...

1)Is the bitrate (25,000~40,000) for the BluRay going to be too high for the computer to take, (the choppy, sloppy, thing i was mentioning above).

2)Is there a way to calculate what a decent range for the bitrate should be for a modern harddrive?
2a. Such as MKV or AVC at or around 10,000 ~ 15,000 kbps

I did try to search but either there is nothing to answer my question or I just truly have no idea what i need to look at. Thanks.

As of 2010, a typical 7200 rpm desktop hard drive has a sustained data transfer rate up to 1000mbps. a dvd - 10mbps, blu-ray - 50mbps.

not much to worry about there, hard drives are not a data transfer problem.

You may still experience playback problems (especially with HD and/or H.264) if you have a weaker video card, weaker settings, lacking software, lacking hardware, etc, but it won't be from a modern hard drive.

According to your computer specs you can play high bitrate hd files on your harddrive.

Hard drives are usually spec'd as mega bytes per second. Video bitrates are usually reports as kilo bits or mega bits per second. Even the slowest hard drives these days can sustain 20 mega bytes per second -- that's 160 mega bits per second. As was pointed out faster drives can deliver 1000 mega bits per second. DVD maxes out at about 10 mega bits per second, Blu-ray at about 50 mega bits per second. Your 480 GB Hitachi drives can probably sustain 300+ mega bits per second.

Just for the record, yes DvD does max out around 10mbps with the DvD standard. But actually DvD can handle higher than that, up to 15mbps, like DivX/Xvid in higher bitrate HD or blu-ray content on DvD blanks.

Whether it plays or not is up to the player since they are non-standard with, both, DvD and BD but the physics of DvD and its red laser can handle it.

Not that relevant to this thread, but thought I'd point it out for those that may need it.
