I have read of many peoples computer builds online, and I commonly see that in the higher end builds, many of their OS's are installed onto an SSD while another HDD is used as a data disk. I was wondering what the advantages of this are.
I am slightly confused because I thought that in such a configuration, the drives write data at the speed of the slowest. I probably am mistaken though.
Also, I am uncertain of the advantages of having the OS on the SSD rather than other data. Is it for faster system start ups?
Could any of you offer your knowledge?

SSDs do not have any moving parts. That being said they offer faster read/write speeds because they do not depend on spinning disks. SSDs are also less vulnerable to failure (although not necessarily always the case) and use less power. SSDs are still new and more expensive per GB compared to HDDs
The speeds will only revert to your slowest drive if:
they are configured in a raid array
they are connected via IDE where there is a master and a slave drive

No, they only write at the speed of the slower drive in RAID arrays, which is why two of the same kind of drives are often used for these arrays.
If an OS is installed on an SSD, the OS will boot MUCH faster. Not only that, but if there is any space left over, it can become a sort of 'cache' for you to store certain files. For example, if you were going to a LAN party, you might want to put a few game files on the SSD so that the games load faster. You may want to keep IDE's there if you are a developer. This kind of setup gets the best of both worlds: a small, relatively inexpensive SSD to install your most-used files on, and a large, slow HDD to put your pictures, movies, music, etc.

the main advantage is the speed, the read and write speeds are much higher, usually double or more then a standard hard drive. this makes loading times much faster.
some people like to keep there computers quiet, since SSD's have no moving parts, there silent.
in a laptop they are more power efficient and will extend battery times.
less chance of failure since there are less moving parts to get worn.
