While Charles reports he’s had one dropout of AirDisk (My name for Airport Disk) since 7.1.1 shipped, I’ve had an entire day of a disk mounted and operating quickly, about 2-3MB/s, over 802.11n and USB 2. Not bad I guess.
I even used ChronoSync to sync 25gb of data to the AirDisk. Its been going for hours now, but no hiccups.
Next test will be in the morning after the drive has had a chance to sleep.
