SATA revision 3.2 also incorporates the M.2 form factor, enabling small form-factor M.2 SATA SSDs suitable for thin devices such as tablets and notebooks. M.2 (formerly known as NGFF and defined by PCI-SIG) is a small form factor card that supports a variety of applications including WiFi, WWAN, USB, PCIe and SATA.
Additional key features and enhancements of revision 3.2 include:
- microSSD - standard for embedded solid state drives (SSDs) that enables developers to produce single-chip SATA implementations for embedded storage applications.
- Universal Storage Module (USM) - enables removable and expandable storage for consumer electronic devices. SATA revision 3.2 introduces USM Slim, which reduces module thickness, allowing smaller removable storage solutions.
- DevSleep - the lowest yet level of power management where the drive is almost completely shut down, to meet the requirements of new always on, always connected mobile devices such as Ultrabooks.
- Transitional Energy Reporting - provides the host with detailed information about the SATA storage device, facilitating better power management.
- Hybrid Information - provides a mechanism in which the host can communicate data caching information to the drive, improving solid state hybrid drive (SSHD) performance.
- Rebuild Assist - speeds the data reconstruction process in RAID configurations.
