ObjectiveFS takes a different approach to high-availability durable file system by using S3 as the storage backend and building a log structured file system on top. This leverages the durability and scalability of S3 while allowing e.g. git cloning/diffing of a large project (even cross region) to remain fast. To compare we have some small file benchmark results at https://objectivefs.com/howto/performance-amazon-efs-vs-obje... .
