Setup 1 - 9TB (Assume Raid 5)
1 x 421+ - $775
4 x WD Red 3TB - $207 x 4 = $828
Total = $1603

Setup 2 - 3TB x 2 = 6TB (Assume Raid 1)
2 x 212j - $270 x 2 = $540
4 x WD Red 3TB - $207 x 4 = $828
Total = $1368


$1603 - $1368 = $235 (ie 1 WD Red 3TB with spare change)

So in the end you get same diskspace except that in Setup 1 3TB is unprotected per se.

Any other views?

2 drives fail at the same time is quite a rare thing lah. Really just sway sway got power trip at my home out of the blue, switch back on 2 drives uplorry. The drives I'm using also not really built for NAS use anyway, so sway lor.

I got myself an APC UPS, one with a USB connection to the NAS. Mine is APC Power-Saving Back-UPS Pro 900 but no need get until so hardcore one lah. I have this habit of buy one time buy a good unit so no need to think about it again. Think cost me around 325.

Now I configure my NAS to become the UPS server, so my UPS is connected directly to my NAS, my PC also connected to the UPS, and set it up to ping every 30 minutes since my PC is only switched on when I am at home. So if see my UPS start to kpkb know got power trip can shut down liao. :s13:

If I'm reading this correctly, your NAS is configured to let you know when the UPS kicks in during a power failure? How is this information sent to you?

If you check the power setting in your NAS, you will find an option to check if your NAS can communicate with the UPS via an interface (most of the time USB cable from UPS to NAS/PC). So when there there is a trip, the UPS will kick in and tell the NAS that it is on battery power. I told my NAS to shutdown within 5 minutes of getting that signal. :D

My PC will do the same if I happen to not be there.

There is no simple way to do it unfortunately. You have to copy it all to somewhere before you can do it. Upgrade to another Synology NAS is just a matter of plugging out the old drives and putting them into the new one, but changing the drives is an entire different ball game.

Ok cool, I suaku didn't know it can do that. Maybe I will go get a UPS then, sounds like a good investment to protect against trips and such. My study does have a problem with tripping sometimes, think I have too many stuff on the grid. Any recommendations on a simple UPS?

Thanks. It seems, I have to decide now whether to go for maximum capacity or not, which I may not even use up.

Can anyone help me with this problem?

I got a router behind router warning from my 2Wire RG.

My RG is connected to a gigabit switch and rest of my devices (and DS212j too) are connected to the network switch.

The reason you want a 412+ is for the intel processor, faster speeds and transcoding feature only found on the 412+ and other Intel NAS. If none of those features makes sense to you, then don't put the 412+ in your list. Not a very fair comparison. You should replace the 412+ with a 413j.

Setup 1 - 9TB (Assume Raid 5)
1 x 413j - $475
4 x WD Red 3TB - $207 x 4 = $828
Total = $1303

See? It's actually cheaper. I rather just go with a 4 bay NAS with a cheap UPS which is even more secure than running 2x2 NAS.

Few questions.
1. How do i check whether i am on RAID-5 or SHR?
2. I downloaded the Apps DS-File. But when i try to open MKV video file on my iPad, it says video format not support. I then install DS-Video in my iPad, but unable to connect to NAS. Any guide that i can refer to?

Many thanks.
