Recently, SATA interface marked its 13th anniversary. Between now and 2013, its performance has increased significantly – from 1 Gbit/s (rev.1.0) up to 6 Gibt/s (rev.3.0). Followed by the growing demand of the market, especially for mobile sector such as laptops, netbooks, ultrabooks, a new revision of SATA – mSATA (rev.3.1) was introduced back in 2011. Basically, it was the same SATA 3.0, in terms of speed, but supporting devices in a compact form-factor (similar to PCI Express Mini Cards, but with different electrical compatibility) that allowed users to use the newest models of solid-state drivers (SSD) and had some additional features, such as:
- Required Link Power Management that reduces overall system power demand on some SATA devices
- Queued TRIM Command, that improves SATA solid-state drives performance
- Hardware Control Features that enable host identification of SATA devices capabilities.
- Support of computer expansion cards with larger PCBs (Printed Circuit Boards) and associated connectors.
- Support of PCI Express 3.0 (through AHCI or NVE drivers), SATA 3.0 (Legacy SATA) and USB 3.0 (with USB 2.0 backward compatibility) bus-supporting devices exposed through the M.2 connector. An outstanding feature, that allows to use of not only storage devices such as SSD, but also Wi-Fi, Bluetooth and GPS modules, NFC (Near Field Communication) devices, digital radio, WWAN (Wireless WAN) and WiGig (Wireless Gigabit) devices.
- Provides up to four PCI Express lanes one logical SATA 3.0 port thought the same connector.
- Enables lower power consumption for the devices that are always on, while being in low-power mode through the DevSleep feature.
- Ensures higher performance for the Hybrid SSDs through the Hybrid Information feature.
