Look at his screenshot. See the partition type "Other" rather than "NTFS"? I suspect those are recovery partitions created by the manufacturer.

There are good reasons for partitioning a drive. One is keeping all your active data (OS, Programs, Games) on the edge of the drive, and storing non-essential stuff (Pictures, videos, etc.) at the slower end of the drive. When drives start to get quite full, it makes a huge difference.

Picture a drive where it's 90% full. If you have one big partition and download a Steam game, it ends up at the end of the drive. That means max ~60MB/sec sequential speeds, and that means long loadtimes. After all, that's roughly what old PATA drives got. Now, if you partitioned smartly (say 25/75%, or whatever percentage gives you enough room), when you download that game it ends up much closer to the edge, and has max ~150MB/sec sequential speeds instead.

The loadtime difference is quite large. If you control where data ends up, it could mean having loadtimes of 20 seconds or 45 seconds for a game. There might be less stutters/jolts as well (depending on the engine), since drives seek faster closer to the edge.

And instead of 2 physical hard drives that can access data on 2 drive letters at the same time on a partitioned drive you will run slower as it is fighting to access 2 drive letters over the same disc and possibly the same platter which in the long run would be even slower access times, This is why I have several hard drives and store things on those drives according to what I need to access. Media and stuff I rarely access goes on drives that only spin up when accessed and my games and such stay on the main drive, I rarely need to defrag using my drives this way as stuff is not thrown all over the main drive.

Dedicated drives is even better.

Sharing storage (static data) with active data won't slow a drive down, as long as you segregate the data. (Keep the stored data at the end, keep active stuff at the front) But a drive sharing active data with other active data will slow it down. (For example, OS/Apps + Games)

Having a shared OS+Games drive is a good way to increase the odds of having stutters. Games generally take up a lot of space, so as you fill the drive with new games that you enjoy playing, the head will have to seek further and further in and sequential speeds will drop. While playing occasionally your OS or background apps will require reading or writing something - the drive will have to seek all the way to the front of the drive to do it, then all the way back. While short seeks can take around 7-8ms on a 7200RPM drive (under half a frame @ 60fps) and ~10-11ms on Greens, long seeks take about double that, and then the drive also has to long-seek back. 30-44ms may not seem like a lot, but it's 2-3 frames that a game couldn't stream data in. If the games had a dedicated drive to run off of, there would be no such interruption, and it could continue streaming textures/models/mapdata in without any delay.

Note: The Games drive could be shared with pictures/video/etc; I would partition the drive in two, keeping the static stuff closer to the end of the drive. But never do that with active data - don't put OS/Apps on the Games drive if you can avoid it, and don't put stuff like music on the Games drive if you listen to it while playing. HDDs hate multitasking, so you don't mix active data on the same drive if you want the best performance. If stuff is simultaneously accessed and you need the best performance, split it off to its own drive. thumb.gif (Although in the case of music, I would probably just stick it on my OS/Apps drive - assuming you don't have a ludicrous quantity, of course.)
