Choosing a Storage Device Isn't Easy

I'm building a new computer and one of my goals is to get my storage off of my computer and onto an external device. This means a NAS (or a DAS), and something that will soon be one of the most important pieces of equipment that I own, possibly the most important. Caveat: this is just a collection of my notes at this point. I hope it helps me decide and it can help someone else down the road. I'll be periodically updating it, as more ideas/notes come to me. I tend to over-analyze decisions like this so let me apologize preemptively. What do I need:
  • Redundant storage
  • Maximum reliability
  • At least two disks
  • Easy to use
What do I want:
  • Scheduled backups
  • BitTorrent client
  • Reasonably speedy connection to my PC(s)
  • NAS to NAS backup
What are my top choices right now?
  1. Drobo 2.0 - $500 Looks to be ridiculously easy to use. It's available in a diskless SKU and can handle different disks.
  2. Netgear ReadyNas Duo - $400 (with 500GB disk) Very complete feature set. More affordable than other options. It's a NAS.
  3. Synology Disk Station DS207 - $289 Looks good, but I don't know much about it.
Possible Choices, but somewhat problematic
  1. HP MediaVault mv2120 - $299 (with 500GB disk) It's affordable. Should have everything I need. I haven't been hearing the best stuff about it, seems very limited.
  2. Buffalo LinkStation Pro Duo - $279 Very affordable, but reviews are not great. It seems like it failed a simulated drive crash test- that's not good.
Who are some of the other players?
  • Buffalo
  • D-Link
  • Thecus
  • Western Digital
  • Lacie
  • Maxtor
  • Iomega
Other recommended products:
  • Buffalo LinkStation Mini - GigaOm Size isn't really a factor for me and I am concerned that this is fanless. SmallNetBuilder likes it but seems to recommend the ReadyNas Duo over it.
=== Notes === 8.28.08 9.35p - Added Buffalo Linkstation Pro Duo to Possible, downgrade HP MediaVault to possible.
