Recently got an 8GB MicroSDHC card for my Connect. Synced 1526 songs on it (7.3GB). Syncing the songs onto the card was remarkably fast. Unfortunately, once the card was inserted, it took 6 1/2 minutes (that’s 390 seconds) for the Connect to read the songs and add them to its database.
Not necessarily unacceptable, just an FYI … I’ll be sleeping my Connect instead of shutting it down from now on.
