Záleží, jestli si stahoval dvě fotografie, nebo milion, jakou měli velikost, jestli je to USB 2, nebo 3 atd.
Chová se to stejně i v jiném OS, jestli ano, pak to není problém Ubuntu.
Těžko radit.
Koukni na tohle, to ti snad něco napoví

Connected to a computer with USB 2.0, the Sony RX100 II's download speeds are decent, though not particularly fast. Note that we used fast 95MB/s UHS-I SDHC card, so slower cards may result in slower download speeds.
Bottom line, the Sony RX100 II is very fast at autofocus, shutter lag, single-shot cycle times and JPEG continuous mode, however powering up and shutting down is sluggish, and burst speed drops when shooting RAW (though still not bad).
