Just one partition.
To illustrate, the read on the hard drive is about 100 MB/s. High definition video like blu-ray has a maximum bitrate of 54 Mbit/s. There are 8 bits to 1 byte. Even older hard drives won't have any problems playing high definition video.
Thanks for the feedback. I know the bit/byte conversion, but wasn't certain what speed HD video was read at, so that's quite helpful. Logically, I would assume that if the source media maxed out at 54 mbits, encoded containers such as .avi or .mp4 would play at even lower bitrates? If so, I really don't have anything to sweat it would seem.
I am curious how I ended up having issues on occasion with video playback off the older disks that I had been using. Could it be that the issue was caused by attempting to play existing data on the same disk that was simultaneously the source/destination for torrent transfers? *disclosure- not into pirating; I only download recent episodes of certain programs to suffice until the season is available on DVD/BluRay*
Heck, maybe the drive was just getting glitchy from old age, considering it was a hand-me-down from another rig that had been using it for years.
