1 Enterprise Flash Drive A evolução do armazenamento de dados Tutorial sobre as tecnonologias SSD (Solid State Disk) e sua implantação pela engenharia da EMC, denominado EFD (Enterprise Flash Drive), onde foram eliminadas as restrições para o seu uso nas aplicações críticas 24x7. EFD foi lançado pela EMC em janeiro/2008 e já é um sucesso de utilização nas áreas de TI em pequenas, médias e grandes empresas (inclusive no Brasil).
