Firstly conceived and still used today for optical storage devices (CD-RW drives, DVD drives, etc.), several manufacturers offer external portable USB hard disk drives, or empty enclosures for disk drives. These offer performance comparable to internal drives, limited by the current number and types of attached USB devices, and by the upper limit of the USB interface (in practice about 30 MB/s for USB 2.0 and potentially 400 MB/s or more for USB 3.0). These external drives typically include a "translating device" that bridges between a drive's interface to a USB interface port. Functionally, the drive appears to the user much like an internal drive. Other competing standards for external drive connectivity include eSATA, ExpressCard, FireWire (IEEE 1394), and most recently Thunderbolt.
answer:
Several manufacturers offer what?

question:
The Protoevangelium of James, an extra-canonical book, has been the source of many Orthodox beliefs on Mary. The account of Mary's life presented includes her consecration as a virgin at the temple at age three. The High Priest Zachariah blessed Mary and informed her that God had magnified her name among many generations. Zachariah placed Mary on the third step of the altar, whereby God gave her grace. While in the temple, Mary was miraculously fed by an angel, until she was twelve years old. At that point an angel told Zachariah to betroth Mary to a widower in Israel, who would be indicated. This story provides the theme of many hymns for the Feast of Presentation of Mary, and icons of the feast depict the story. The Orthodox believe that Mary was instrumental in the growth of Christianity during the life of Jesus, and after his Crucifixion, and Orthodox Theologian Sergei Bulgakov wrote: "The Virgin Mary is the center, invisible, but real, of the Apostolic Church."

question:
In addition to debates on religion, societies discussed issues such as politics and the role of women. It is important to note, however, that the critical subject matter of these debates did not necessarily translate into opposition to the government. In other words, the results of the debate quite frequently upheld the status quo. From a historical standpoint, one of the most important features of the debating society was their openness to the public; women attended and even participated in almost every debating society, which were likewise open to all classes providing they could pay the entrance fee. Once inside, spectators were able to participate in a largely egalitarian form of sociability that helped spread Enlightenment ideas.

From a historical standpoint, what was one of the most important features of the debating society?
