What is UASP?

USB Attached SCSI Protocol is a more efficient technology for the transfer of data over a USB connection. Although USB 3.0 is much faster than USB 2.0, its full performance cannot be unleashed without also upgrading the existing data transfer protocol, known as Bulk-Only Transport (BOT).

Most USB 3.0 devices will operate using BOT unless specific drivers are installed and UAS compatible hardware is used at each end of the connection. Some vendors, such as Asus, have released UASP drivers for Windows 7; full native OS support was introduced with Windows 8.

What is an Ultrabook?

A marketing term for a laptop that has been built to a specification set by Intel, in order to ensure a high-quality user experience. The requirements change as new chips are released and, for Ivy Bridge systems, currently include fast startup, a maximum thickness that varies according the screen size, and a battery life of at least 5 hours.

What is Unix (operating system)?

A popular multi-user, multitasking operating system developed at Bell Labs in the early 1970s. Created by just a handful of programmers, UNIX was designed to be a small, flexible system used exclusively by programmers.

UNIX was one of the first operating systems to be written in a high-level programming language, namely C. This meant that it could be installed on virtually any computer for which a C compiler existed. This natural portability combined with its low price made it a popular choice among universities.

What is USB 3.0?

Version 3.0 is the fastest USB standard to date, and is increasingly becoming available in the latest PCs and laptops. USB 3.0 provides connection speeds around 10 times faster than its predecessor, and offers more power to external devices.

USB 3.0 ports tend to be blue, but some are black.
