A 3.5-inch Serial ATA hard disk drive A 2.5-inch Serial ATA solid-state drive. SATA was announced in 2000 [4] [5] in order to provide several advantages over the earlier PATA interface such as reduced cable size and cost (seven conductors instead of 40 or 80), native hot swapping, faster data transfer through higher signaling rates, and more efficient transfer through an (optional) I/O queuing ...
[3] [6] The SATA revision 3.2 specification, in its gold revision as of August 2013, standardizes the SATA Express and specifies its hardware layout and electrical parameters. [1] [30] The choice of PCI Express also enables scaling up the performance of SATA Express interface by using multiple lanes and different versions of PCI Express.

The SATA revision 3.2 specification, in its gold revision as of August 2013, standardizes M.2 as a new format for storage devices and specifies its hardware layout. [2]: 12 [8] Buses exposed through the M.2 connector include PCI Express (PCIe) 3.0 and newer, Serial ATA (SATA) 3.0 and USB 3.0; all these standards are backward compatible.
Device interfaces where one bus transfers data via another will be limited to the throughput of the slowest interface, at best. For instance, SATA revision 3.0 (6 Gbit/s) controllers on one PCI Express 2.0 (5 Gbit/s) channel will be limited to the 5 Gbit/s rate and have to employ more channels to get around this problem. Early implementations ...
In September 2004, revision 3.0 was released, bringing to the ACPI specification support for SATA interfaces, PCI Express bus, multiprocessor support for more than 256 processors, ambient light sensors and user-presence devices, as well as extending the thermal model beyond the previous processor-centric support.
The COM Express specification is hosted by PICMG. It is not freely available but a paper copy may be purchased for $150USD from the PICMG website. [3] However, the COM Express Design Guide is free to download. The original revision 1.0 was released July 10, 2005. Revision 3.0 (PICMG COM.0 R3.0) was released in March 2017.
When used with an SSD, UAS is considerably faster than BOT for random reads and writes given the same USB transfer rate. The speed of a native SATA 3 interface is 6.0 Gbit/s. When using a USB 3.0 link (5.0 Gbit/s), which is slower than a SATA3 link, the performance will be limited by the USB link.
