Advice Plz... HD Videos to PS3 with ReadyNAS Ultra 2

It provides you a growth path in the size of your volume. Saving video files eats up drive space at an alarming rate. I started with 2x500GB drives in an NV+ and that 500GB volume was more than enough for years. When I started copying video files, my volume started growing. I expanded my NV+ to 3x500GB and 1x750GB drives for a volume of almost 1.5TB. I then upgraded to an NVX with 4x1TB drives which gave me a 3TB volume. In the space of a year, my data usage expaned from 800GB to 1.7TB.

I recently started expanding my NVX vetically by replacing some of my 1TB drives with 3TB drives. A dual bay unit with redundancy will only give you the space of 1 drive. While you can start with 2x2TB drives, that only gives you a net volume of 1.8TB. If you start with a 4 bay unit, you can start with only two drives and as you need to expand, you simply add additional drives. Then when you max out, you can upgrade to 3TB (or simply add 3TB drives instead of 2TB in the second two bays). X-Raid2 in the x-86 will expand vertically once you have 2 drives of the larger size rather than having to wait until all drives are the new size as is the case in the older X-Raid found in the Duo/NV+.
