 ## Choosing a Storage

-| ----------------------- | ----- | ---------------------------- | ----------------------------- |
-| **MemoryStorage**       | Sync  | Development, small datasets  | Zero config, bundled          |
-| **FsJsonStorage**       | Async | Persistent local cache       | File-based, survives restarts |
-| **NodeCacheStorage**    | Sync  | Production single-instance   | TTL support, multi-ops        |
-| **LRUStorage**          | Sync  | Memory-constrained apps      | Auto-eviction, size limits    |
-| **RedisStorage**        | Async | Distributed systems          | Shared cache, redis v4        |
-| **RedisIOStorage**      | Async | Distributed systems          | Compression, modern ioredis   |
