The Organization Serial ATA International Organization (SATA-IO) has announced the ratification of SATA 3.2 specification. The new version includes a standard SATA Express - a new specification that ensures coexistence drives with SATA and PCIe. In addition, the standard made improvements to power management, new form factors SATA and optimization, to improve the operation of hybrid drives.
Specifications of SATA Express which began in January , provide the ability to use SATA and PCIe in client data stores. Host corresponding to these specifications will be able to simultaneously work with hard drives, equipped with a SATA or PCIe. Using PCIe provides a speed of up to 2 GB / s (two lines PCIe 3.0), which significantly exceeds the capabilities of SATA 6 Gb / s (0.6 GB / s). This creates the potential for further increasing performance SSD and SSHD. Drives that do not need such a high speed, for example, HDD and optical drives will be able to use SATA.
In SATA 3.2 fixed form factor M.2, designed for drives used in ultra-thin notebooks and tablets. Earlier it was known under the designation NGFF.
In addition, the audit included 3.2 standard microSSD, which will create a monohull built in storage interface SATA, and the specification of Universal Storage Module (USM), which describes the removable and expandable storage for consumer electronics devices, supplemented by a description of modules of reduced thickness USM Slim.
Standardized by the lowest level of power consumption DevSleep, in which the drive is almost completely off. This mode is designed for devices that are always on and connected to the network, such as laptops Ultrabooks.
Other innovations include the function Transitional Energy Reporting, which tells the host detailed information about the device interface SATA, which improves power management, the function Hybrid Information, which provides a mechanism by which the host can transmit information about the hybrid drive caching to improve performance SSHD, and feature Rebuild Assist, accelerating the recovery process data in the RAID array.
The new version of the SATA specifications is available at SATA-IO.
