I have issues getting open NAT for both my Xbox one and the PS4. My settings are Modem>Router1 (Router2/Router3-Bridged)>Device.

I have a tablet and it has a 3500 MAh battery. If I fully charge the battery then Battery Doctor says that it will last for 12 hours. In real, it lasts for only 5 hours in maximum if I use it at normal level. Is it normal? Why is the battery draining too fast as far as I know?

I have an old pc with a dated motherboard which does not permit any major updates. I heard that such systems can be easily used as servers to host shared files.

I bought 3 SSDs, 2 of which are 850 evo and the other 840 evo 256GB. Each individual drive has half a GB in speeds. I am using a Raid controller but it can not allow me to raid them. I am now looking for a new Raid controller that is on new egg but I still do not know if it is worth it. Will I get 1.5 GBs out of it when in raid 0? Since I have only the PCI 2.0 4x slot to use with the 970 and a x16 slot, should I go ahead to get the new controller?

Last night, I found my old 80GB hard drive which I had formatted and disposed few years back after I bought the new PC.

If imaging is the best idea, help me out to image it perfectly.
