The SATA-IO group recently confirmed revision 3.2 SATA includes ensuring support SATA express. The standard SATA goes into high gear with the version 3.2, which has been approved by the SATA-IO association, the umbrella organization of the SATA standard.

SATA Express takes

SATA Express Versus SATA

The SATA standard associated with the internal storage in PC, such as SSD, hard drives and optical drives, The SATA Express (originally announced in January 2013) comes up with a new specification that enables the coexistence of SATA and PCIe.

This is a major innovation as it increasing the bandwidth of the internal bus of PC covers the way for integration of storage devices swifter and therefore more efficient PC.

While the speed of the SATA 3 capped at 6 GB/s, PCIe Gen 3 on two ports (PCIe x2) up to 2 GB/s or 16 GB/s. To operate at these speeds, the host controller and storage device must support this new version of SATA.

3.2 extends the safeguard of SATA

It seems SATA technology continues to evolve to reflect the changing requirements of the storage industry, updates contained in the specification of 3.2 as support SATA Express and improvements for emerging SSHD are driven by current market trends. These new features demonstrate the continued commitment of SATA-IO to provide storage solutions at low cost and high performance.

With the revision 3.2, the SATA standard goes indeed to date with the introduction of new features.

Specifically, the new specification supports the following:

Support Micro SSD: a standard single-chip SSD for embedded storage
  1. Support the Universal Storage Module, a removable storage module for laptops and ultra books
  2. The compatibility factor M.2 form linked to consumer electronics
  3. DevSleep, a new low-power state in which the reader is almost completely extinguished
  4. Transitional Energy Reporting: Provides detailed information on the host controller SATA storage device to facilitate energy management information
  5. Hybrid Information: provides a mechanism in which the host can communicate information cached data to the drive to improve the performance of SSHD (solid state hybrid drive)
  6. Rebuild Assist: helps accelerate the reconstruction process data in RAID
Specification of revision 3.2 SATA is now available (free to members of the SATA-IO group and a fee of $ 40 for non-members).
