Free drive offer and ReadyNAS Pro 6

As one who looked at various options years ago, I am glad that I opted for the ReadyNAS NV+ four and half years ago. While I know the offer of a single 3TB drive can make a difference, over the years the reliability and ease of setting up on the ReadyNAS makes it a no brainer for me. My NV+ has now been joined by two NVX units which are a year and a year and a half old. One is the primary and the other the backup target. My trusty old NV+ which has had it's OS updated about four times (but is now again one version older than current) and the drives upgraded twice. It provides the backup of critical files (movies excluded) of the backup unit which is a backup of everything.

I have eyed the Pro for some time my self, but even when the Pro Pioneer and Pro Business were being updated to the Pro 6 and Ultra 6 Plus, I was having a hard time justifying the additional cost of 6 bays over 4. I opted for the NVX because it was half the price of a Pro Business at the time and I still don't have near the data to fill my NVX (currently 2x3TB and 2x1TB drives for a volume of 4.5TB and I am only using about 2TB. Unless you really need the 6 bays, you might want to consider a Pro4.
