NEW SATA 3.2 Specification
SATA Express:
– Includes both SATA and PCIe signaling
– Hosts supports both SATA or PCIe storage device.
– With PCIe transfer rates of up to 2 GB/s (2 lanes of PCIe 3.0), compared with
today’s SATA technology at 0.6 GB/s.
M.2:
– 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.
Additional features of the SATA-IO Revision 3.2 Specification 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 level of power management yet, where the drive is almost
completely shut down, meeting the requirements of new always on, always
connected mobile devices such as Ultrabooks™.
