Hello I did check existing threads - but the other person asking a similar question bought something else So....this is my first foray into buying a NAS. I have been doing a bunch of research, and I think the above two fit my requirements [read budget]. They currently cost exactly the same price, and I am struggling to determine which is better for me. Requirements 1. Streaming media - at the moment only music, but I do have all the toys like Wii, XBOX360 and PS3 and a HD 1080p TV - so video streaming may be an option later 2. I have 2 PCs and 2 iPhones [with a laptop and/or tablet in the near future] 3. Back up My understanding is that running in RAID 1 will give me a back up - but reading elsewhere this is actually just a redundancy disk and I would still need to back up my data. If that is true, then would a 1 bay suffice? The following are all priced similarly QNAP TS-112-US and Synology DS112j . This one has a 1.6 processor QNAP TS-119P+-US, has the most memory at 512 MB and is priced the same as the 2-bays above. Comments? Advise? Thanks for any feedback.
