I've been scratching my head thinking about the best sever storage solution for my web app.

It's a productivity tool where people can upload files - lots of them. I run my own server in a colocation environment. I don't want to use cloud storage services like AWS, Google Cloud or Azure, because my colocation company gives me unlimited traffic for free, ingoing and outgoing.

I want a RAID solution (RAID 1 or RAID 5) that is easy scalable in case I get a lot of costumers.

What is your experience with scaling RAIDs? I'll start with 4 TB and want to be able to expand it to, let's say, 120 TB one day (but virtual no limits)

Thanks, Matthias

In itself I would not call RAID scalable, especially RAID1 (simple mirroring). RAID5 would be managable, but if you add more disks, you need to reorganize the array.

With these requirements in mind, I would consider setting up ZFS with RAIDZ, so you can add extra disks on the fly.

I found a nice solution. I will simply add additional raids to my server and connect the folders via SYMLINKS to the already existing filesystem. So, my OS doesn't care on which RAIDs my files are stored and I can add storage on-the-fly.
