alt Hacker News> Redis is as reliable as the storage you persist it to.
For a single node, if you tank performance by changing the configuration, sure. Otherwise, no, not really.
I don't get why you'd want a file system that isn't durable, but to each their own.

With the wal redis runs with perfectly reasonable performance. Of course you're not going to have the performance of an in-memory only DB if you're flushing to disk on every write.
There's no vacuuming, there's no need for indexing. You can see the time complexity of most operations. Key-value operations are mostly O(1). You'll never get that kind of performance with other databases because they intentionally don't give you that granularity.
The metadata of the filesystem isn't the performance bottleneck in most cases.
