I will get Intel X25-M 80gb but need another drive for storage.
Looking for: Quality, Reliability, Longevity, Speed. (Preferably Western Digital)

WD Velociraptor 10k rpm is by far the best bet for performance... you didn't specify your price range tho.
the best storage drive is the samsung spinpoint f3 1tb it's a recommended here at tom's it's much better than western digital it's high quality reliable beats the the velociraptor 300gig drive in some benchmarks
