ja znalazłem coś takiego http://digitalphoto.maccreate.com/20...al-hard-drive/
w szczegolności: "I measured impressive write speeds of 40MB/sec when copying images from a Lexar 300x UDMA card using the Lexar UDMA FireWire 800 reader connected directly to the My Book Studio drive. I was able to transfer 2.62 GB of RAW image files (14-20 MB each) in just 65 seconds. A huge time savings for any photographer using large UDMA cards."
co prawda nowszy dysk ale powinno być podobnie
