Database servers using NAS as storage? (alien.top)

I am thinking of running multiple database/messages servers such as postgres, redis, mongo, influxdb on old computers and use a centralized NAS to store the data.

One advantage is that I don't need to worry about getting appropriate local storage for the computers that host these services. For example, I could run postgres on an old desktop with spinning disks or even a raspberry pi.

But I am still concerned about the I/O speed and reliability. I wonder if anyone has experience doing it like this. Can you share the pros and cons? I really appreciate it.

Thanks, everyone. My motivation was to turn the many little computers with tiny or slow disks into servers by adding some centralized storage. But it looks like NAS today is not a good solution for this -- at least not yet. I appreciate all the insights.
