Hi all
I'm not very good in IT but I manage to follow instructions and do good
I'm buying my first NAS at home (synoligy DS416j) , and planing to get 4 hard drives (4tb or 6tb) depends on the budget the 4 will be same model same size
My questions
I was told better to go with WD red hard drives , hope it's an honest suggestion
2nd should I go with raid ? And which one ? Some say raid 0 and some say raid 5 ! Or shall I use the synoligy hybrid raid ?
This NAS will be for my multimedia files (Huge amount of movies and series and music ) and my PCs / phons backup
I'll be connecting it with KODI to stream my media , my home network is a regular 10/100 network useing a 4 port Cisco router for ADSL and network

Sorry for being long but I wanted to give as much Info and details as I can

With 4 drives you will get more space (with less redundancy) with SHR or RAID5. If 8TB (with 4TB disks) is enough space, you get more redundancy with RAID10. If you EVER lose a disk in the SHR or RAID5, you are at risk for data loss until the volume rebuilds. That can take a long time with 4TB disks. RAID10 has the potential to handle a second disk failure during rebuild. That is why RAID10 is gaining popularity.

BUT, I will stress that RAID (any type) is not a substitute for backups. You should ALSO have a USB drive on the NAS to backup any critical files. Movies might be inconvenient to lose, but family photos will cause BIG problems if lost... It is all a question of risk tolerance. My family photos go from my PC to my...

WD RED drives should be fine. The type of RAID, and you probably do want some kind of RAID will depend on how much total space you HAVE to have. SHR or RAID5 would give you 10+TB with 4TB disks. RAID 10 would give you 8TB, but could survive two disk failures.

Remember that RAID is not a substitute for backups. It only protects against physical disk failure. There are lots of ways to lose data. You should also consider a USB3 drive on the NAS as a backup for the NAS.

Popatim :
I just need to store my multimedia (about 5tb) collection and stream from it useing kodi
I was gonna go for a 2 bay NAS but since the data is huge I thought a 4 bay would be better specially if I'll go with raid 5

The default RAID is the Synology SHR. I used it on my two drive NAS. My 4 drive NAS was formatted before Synology included the SHR. But I would allow it to use the default SHR if I did it again.

You say my best option is the synoligy SHR ? Cause I honestly don't understand anything about this I tried to read but I got totally lost
I'm really sorry guys to ask a lot of questions but consider me a NOOB when it comes to IT stuff

My family photos go from my PC to my Synology and it then uploads a copy to cloud storage. That way I have an offsite copy, so that even if the house burns down, my pictures are OK.
