Somehow you might miss the notice.

Actually it is not main concern.

I would like pretty much use the cloud. But some con that make me against it.

1) I can't share the pic with family and friend. I want them just simply open the apps in the phone and view my pic/video. Don't need everytime ask me post/FB my pic/video.
2) Troublesome to upload/download video with big size. Specially video.
3) Once you go terabyte, it is not cheap to maintain the cloud. Paying such fee every yrs, can makan roti.  I have 1+TB of file. 

Cloud storage is reliable.

What is not reliable is the networking down and speed.

1) the fee is high for big storage like me. I need at least 2TB which can cost RM86/mth. RM1032/yrs. 
2) NAS server photo sharing is much more easy to share and permanent compare google drive or others. Different kind of sharing and experience.
3) Upload is still pain in the ass. upload speed is much more slower than download. Last week want to backup a 7gb of data into my iCloud cause 3.5hr. Upload to the NAS is less than 10min. A 3days holiday can have a size of album of 20gb.
4) Another good about NAS server is the enjoyment of watching it from TV in your home. You can instantly access it rather from the net.

Currently the famous is this 2, Qnap and Synology.

I m using Synology.

If you using the cost to calculate, A simple 2hdd 4tb NAS can cost RM3k. Probably last you for 6-7yrs lifetime.

Google drive for 2tb a yrs cost RM1032/yrs x 6yrs = RM6192. 
But you still need an external backup even have NAS. Against physical damage and lost.
