Take a look at ReadyNAS Pro Series Performance Personally I'd recommend upgrading to the Pro 6 but the choice is up to you. Welcome to the forum!

Sounds like a good recommendation -- thanks for the extensive responses -- excellent community support. I'm curous though as I generally buy hardware that I expect to have a 7yr lifetime how much performance is going to be left on the table with ram of the pro units limited to 1GB, and no units with 10gigE by default, or even as an upgrade. If I knew the pro6 could have its ram upgraded to 4GB and NIC's upgraded to 10gigE later, that would make me feel much more comfortable shelling out the $ for something I plan to use for an extended period and not just replace a few years later.

Also, do the newer units have any kind of battery for the storage controller nvram? I wouldn't think that would add much to the unit cost given how old the tech is now - although I can see how it might a pain for customers who don't want to replace the battery every few years.
