That depends on how dense the data is. Do you mean un-compressed video, black-and-white video, high-definition video? Un-compressed CD quality music takes about 20 times as much room as MP3 files, but has higher quality. The same applies to video; the more compressed it is to save space, the lower the overall quality.
For example, I'm converting Batman Begins from .wmv at 320x240 to .mp4 at 640x420 to play on my iPad. The .wmv version is 462MB, the .mp4 version is 686GB. It's runtime is just shy of two hours, so we'll say 470MB for the .wmv and 700MB for the mp4. Thus, you can get around 4,400 hrs of video with the .wmv compression and just shy of 3,000 hrs at the .mp4 compression. (That's assuming you have all 1,024 GB to play with on the drive).
Short answer: A lot. It all depends on how compressed the file is, and that's really your choice for what you want to use it for (will it be played on a HDTV or a laptop?) and depends on a lot of factors (i.e. Pre-conversion quality, original file size, etc.)

It can at least hold up to 4 hours of video on the 8GB.
The amount of video that 4 GB can hold depends on the video quality and compression used. For example, standard definition video at a bitrate of 1,000 kbps can hold approximately 4 hours of video, which is about 240 minutes. In contrast, high-definition video at a bitrate of 5,000 kbps would hold roughly 48 minutes. Therefore, the duration varies significantly based on the video settings.
The amount of video that 256MB can hold depends on the video's bitrate and resolution. For example, standard definition video at a bitrate of about 1,000 kbps can yield approximately 30 minutes of video in 256MB. However, high-definition video at a bitrate of 5,000 kbps may only allow for around 5-10 minutes. Therefore, the duration varies significantly based on the video quality and compression settings.
The number of document files that one terabyte can hold depends on the average size of the files. For instance, if the average document file size is 1 MB, one terabyte can hold about 1,000,000 documents. If the files are smaller, such as 100 KB each, then one terabyte could accommodate approximately 10 million documents. Conversely, larger files would reduce the total number of documents that can be stored.
To determine how many minutes of video can be stored in 64 kilobits (Kb), you need to know the bit rate of the video. For example, if the video has a bit rate of 1 Mbps (1,000 Kb per second), then 64 Kb would only hold about 0.064 seconds of video. If the bit rate is lower, such as 128 Kbps, it would hold around 8 seconds of video. Therefore, the duration varies significantly based on the video quality and compression used.
An hour of standard video takes up about 1GB, while an hour of high-definition video sucks up 4GB
The amount of space needed to store video files will depend upon the amount of compression applied to the file. In general one terabyte will store around one thousand hours of compressed commercial movie quality video.
