No matter which system you choose if you don't follow the old rules about backup you get to (re) learn why they came up with that.
Too many people today use such systems as STORAGE and forget about the all important second copy and backups.
I like that HP but for me a simple low wattage LINUX BOX is doing my NAS.
Been looking at HP's MV2020, Netgear ReadyNAS, and Iomega StorCenter. I would entertain other options as well. Things that are important to me are: data security (redundancy, we had a HDD fail and lost lots of pictures of first baby), speed, and media streaming. Any thoughts?
