First off, I love the article and idea that getting ready for tomorrow is not as expensive as you think. If I was suggesting a SMB storage area there would be a couple items concern regarding the NAS:

1. Since the is a business NAS and not for personal use, survivability of disk failure will be a must; so given the parts above, 16TB will never available storage regardless of array model when some level of mirroring is required. I would hate for this or any other article to somehow insinuate that RAID0 is an option for a SMB's off-system file storage.

2. Regardless of the SMB IT solution, reliability has to be a key part. These organizations typically do not have the staffing or redundant systems that the companies hav. Extended downtime or loss of data can be catastrophic to their survival. One investment in reliability has to be the quality of the disk placed in the NAS or SAN. If I were building a solution costing thousands of dollars, I wouldn’t cheat reliability for a few hundred dollars discount. The drives need to enterprise grade which in the case of the mentioned vendor would be something like their Constellation Enterprise Series.

That is just my two cents on this. I have always found that when small businesses skim on the right infrastructure parts up front to save money, they typically end up losing more money within two years due to downtime.

Do it right and weather the storm...
