In 1998, digital audio players (DAPs) based on [[flash memory]] or [[hard disk]] storage became available (The [[Rio PMP300]] from Diamond Multimedia is widely considered to be the first mass market DAP). Files are usually compressed using [[lossy compression]]; this reduces file size at the cost of some loss of quality. The [[trade-off]] between degree of compression and file size can be varied, although this is not an option for existing compressed files. The advantage of solid-state DAPs over hard disks and CDs is resistance to vibration, small size and weight, and low battery usage. Early solid-state DAPs had capacities of a few tens of kilobytes; {{As of|2009|lc=on}} capacities of many gigabytes are available.{{Citation needed|date=August 2009}}
