We just ordered an MD1200 array maxed with 2TB drives to hang off a Dell T710 with a PERC H800 card. Configured as RAID-6 with an extra Hot Swap drive so we have a little extra redundancy as this setup will be in a remote office. Great speed, easy setup and quality build. We decided on the MD1200 because we can easily ship additional arrays to plug in as space requirements grow, and the ability to spec 2.5" and/or 3.5" drives to meet cost vs. performance for project requirements. This setup has become our remote office server/storage/ESX standard.
