Looking at a decent NAS solution with some resilience to store/back up about 1TB worth of archived photos at our school (that will increase over the coming years). Was thinking of one of these Buffalo LinkStation Duo 6TB 2 Bay NAS (LS-WX6.0TL/R1-EU) - www.misco.co.uk Set to raid 0 for mirroring. Then backing up to a 3TB external HDD for offsite storage.
If anyone has any suggestions/info on how you are going about it that would be great.
We use the QNAP TS-400 range for this kind of thing. Pretty solid.
