Windows 7 - Recording live TV - question about configuring hard drives

I am in the process of building an HTPC and am planning on using windows media center and a Ceton Infinitv tuner to record live tv. I have a couple of questions, one of which is related to the configuration of windows media center. Any feedback is welcome -- I am newbie in this realm, and am trying to figure out what hardware I need to meet my requirements:

1. I plan on having a 64GB solid state drive and then a couple of larger traditional HDDs. Can I configure WMC such that I can store the recordings of live TV on the SSD while the recording is in progress and then send the finished recording to another hard drive automatically?

2. This isn't necessarily a WMC question, but is #1 even necessary or will I be ok with the read/write speeds of my HDD without any lag. I'm looking to get a 5900 rpm sata 6.0 Gb/s, but would bump up to 7200 rpm if this is going to make a difference.

Sorry if this is a stupid question, but with the recent jump in HDD prices, I'm trying to get this decision right the first time.
