Instead of buying expensive disk.. I might setup a ramdisk (about 2GB) to do 200 calls recordings. Once the call hangup/completed it will then move recording file to SATA HDD.

Benny is right, if writes are smaller than the stripe size, there is no gain in speed in using raid5. Not only, but you can have lower performance than a single disk. The ramdisk can be a good idea, but if the load is somewhat constant, you end only moving the slow write ahead of time. 200 calls at 64kbit/s are just 1.5 Mbyte/s ... even the slowest disk can accomplish this.
Won't 200 simultaneous calls result in a lot of 'head thrashing' that would be avoided by staging the recordings to some form of non-mechanical storage and then copying the the recording at the completion of the call?
