[EN] Self-encrypting drives (SED)
Esse assunto andou me perseguindo durante a semana. Começou com o Google Compute Engine, informando que *todas* as gravações, sejam em disco temporário ou permanente, são criptografadas automaticamente. Achei estranho (e desperdicio) gastar tempo criptografando dados que não requerem esse tipo de segurança, são voláteis, etc, mas deixei quieto. O assunto retornou, de outra forma, analisando um dos servidores que o Google está instalando nos ISPs, o Dell PowerEdge R720xd, um bicho que além de ter *24* DIMM slots (768GB RAM), tem como opções de storage:
Hot-plug hard drive options:
2.5” SAS SSD, SATA SSD, SAS (15K, 10K), nearline SAS (7.2K), SATA (7.2K)
3.5” SAS (15K), nearline SAS (7.2K), SATA (7.2K)
Self-Encrypting Drives available
SAS e SATA SSD, tem isso é? Mas de novo SED? Novamente ignorei.
Por pouco tempo.
It’s taken nearly a decade for SEDs to approach a tipping point, but that moment seems to have arrived. Seagate, Samsung, Hitachi GST, and Western Digital all produce SEDs today, and self-encrypting support in solid state drives (SSDs) is quickly becoming universal. Compatibility issues have vanished, and SED retail prices are now at near-parity with non-encrypting models. (In the enterprise market, Seagate has erased the price difference altogether.) Perhaps most significantly, Microsoft’s Windows 8 is the first operating system to offer native SED management support.

Windows 8 is the first operating system with native SED awareness, but Microsoft has wisely left its OS and eDrives open to compatibility with third-party security applications.
Security keeps getting better and easier. Windows 8 will likely prove to be the catalyst that pushes SEDs into and through their tipping point. If you haven’t given on-drive encryption any consideration before, now is the time to make the change and ensure that your files stay safe forever.
