It is, however, supported for compatibility reasons by nearly all currently developed operating systems for personal computers and many home computers, mobile devices and embedded systems, and thus is a well suited file system for data exchange between computers and devices of almost any type and age from 1981 through the present. It offers good performance even in very light-weight implementations, but cannot deliver the same performance, reliability and scalability as some modern file systems.
