Im tied in choosing between these two. My main purpose is to stream 500GB of samples for my project and sometimes editing 10 minutes of 1080p video clips. One thing I mind is the Pegasus's noise fan level. I've read that it's quite noisy compared to the nMP. Then the 1TB PCIe, i've been searching in eBay for 2 weeks now. I've seen quite reasonably priced Samsung 1TBs however, with the import charges included (extra $100) it made them no longer reasonable as I have to take into account $50 for shipping (Total: PCIe+$150). I'm leaning more towards the PCIe but the import charges is a huge huge huge drawback.
