So far so good. Did a reasearch and settled for DS223j and chose Computechstore because of the price. In Amazon this is Rs. 2700 more. I chose their EMI option to check out how things work. Assembled with a single 4TB HDD from Synology, as i heard their sync is good. Backed up few photos and found it to be good. Meanwhile the only glitch in this whole buy-scenario is the delivery, which took ages(coming from Amazon delivery speed) and mid-way, since no mails/SMS were received, thought this is a scam. Nothing of that sort happened, I trust this website though. I was being a bit impatient here, i think ;)
