Best use of 10k drives - media storage or running an OS?

My system has 2 drive bay arrays, each with very different characteristics. One is a 1.1Tb array of 10k SAS drives. The other is a 4Tb array of 7.2k SATA drives. Both arrays are RAID10 and everything is running on a wired Gb network.

The obvious options are to
1. use the SAS drives for the media server (W2K8) and the SATA array for storage OR
2. Vice versa.

As it is, with W2K8 running on the SATA array I get network file transfer speeds of around 65-75Mb/s between the W2k8 box and a FreeNAS box. This is according to the applet in Windows Explorer that pops up when you move files around. The W2K8 server will likely be called upon to do a fair amount of transcoding.

Anyway, where am I going to realize the greatest benefit from the faster drives? 1.1Tb is not a lot of storage space, I realize. Under the storage scenario I'd just use it for more demanding applications. Or does it even matter? I understand nothing about the bottlenecks in networked systems like this. :??: Comments welcome, thanks.
 
Solution
The 10K drives would be better suited as your OS and the SATA drives as the media server. SAS drives will have much faster seek times making them much better for random access (loading an OS/program etc.) but likely won't have much advantage for serving up media unless you plan to stream to 3 or more devices at the same time. Reason that web servers use the 10K drives is to accommodate dozens of people downloading small files simultaneously.
