Many reasons........

No real benefit (companies excepted), and issues like you have been posting.

If the RAID controller bites the bullet you are usually toast unless you 
have another RAID controller (same manufacturer and type) as a spare.

I have zero luck replacing one companies raid controller with another 
and ditto on raid built into the motherboard.

I really don't need any help losing my data/files as I do a good job of 
that all by myself ;)

I found it is better to just have my data on several backup disks, that 
way if one fails I get another disk and copy all the data to the newly 
purchased disk.

After removing raid, I completely redesigned my network to be more 
inline with the howtos and other information.

I have little to nothing on the client system I use daily, everything is 
on networks systems and they have certain things they do.

I have a "git" server that has all my setup/custom/building scripts and 
all my programming and solidworks projects.

I have DELPHI build apps going back to about 1995.

It all backed up to a backup server(master and slave) and also a 4TB 
offline external hard drive.  I have not "lost" any information since.

I also found that DHCP and NetworkManager is your friend.

Maybe you should review your network setup as you seem to have a lot is 
issues with it?
