SATA 3.5 specification released: bandwidth has not grown, but there is a chance for performance growth
Eleven years ago, the SATA Revision 3.0 specifications were released, which made it possible to double the peak speed of one of the most common interfaces for connecting hard drives. Today, the revision of the SATA specification has reached version 3.5. The maximum exchange rate remained unchanged and froze at 6 Gbit / s. But the developers of the standard promise to increase overall performance and improve integration with other I / O standards.
In general, innovations in SATA Revision 3.5 boil down to three additional features. The first is the technical function of Device Transmit Emphasis for Gen 3 PHY. It allows you to focus on the transmitter, which equates SATA with other I / O solutions when measuring their characteristics. This function should help at the stage of testing and integration of interfaces of new devices.
