I bought the TS210 after returning a Netgear Ready NAS due to numerous issues.. terrible product .
The TS210 is however a great product, easy to set up and use. I have 2 Macs and a PC each works seamlessly with the NAS. Time machine for Mac works at first attempt.
It took me a couple of hours to set up and understand how the interface works, but after this just a breeze. I configured the two drives for separate access rather than RAID due the way I want to back up large video files for long term storage.
