In the beginning, MP3 players relied heavily on memory-card expansion slots, because built-in memory was painfully scarce. My, how the times have changed. Nowadays, internal flash chips offer up to 64GB of storage, and memory-card expansion slots--which almost exclusively take some form of SD media--are merely offered as an extra feature.

Luckily, there's a decent array of MP3 players currently on the market offering this extra, so if you're keen on the option of adding more space on a whim--or you just want to use memory cards a la MiniDiscs, swapping them in at intervals--you have plenty of worthy choices.

Check out the expandable MP3 players.
