eSATA does not supply power to external devices. This is an increasing disadvantage compared to USB. Even though USB 3.0's 4.5 W is sometimes insufficient to power external hard drives, technology is advancing and external drives gradually need less power, diminishing the eSATA advantage. eSATAp (power over eSATA; aka ESATA/USB) is a connector introduced in 2009 that supplies power to attached devices using a new, backward compatible, connector. On a notebook eSATAp usually supplies only 5 V to power a 2.5-inch HDD/SSD; on a desktop workstation it can additionally supply 12 V to power larger devices including 3.5-inch HDD/SSD and 5.25-inch optical drives.

Even though USB 3.0's 4.5 W is sometimes insufficient to power external hard drives, technology is what?
Answer: advancing and external drives gradually need less power

Czech has one of the most phonemic orthographies of all European languages. Its thirty-one graphemes represent thirty sounds (in most dialects, i and y have the same sound), and it contains only one digraph: ch, which follows h in the alphabet. As a result, some of its characters have been used by phonologists to denote corresponding sounds in other languages. The characters q, w and x appear only in foreign words. The hacek () is used with certain letters to form new characters: s, z, and c, as well as n, e, r, t, and d (the latter five uncommon outside Czech). The last two letters are sometimes written with a comma above (', an abbreviated hacek) because of their height. The character o exists only in loanwords and onomatopoeia.

What character in Czech only exists in loanwords?
Answer:
o
