The HDR-SR1E captures the AV stream to an integrated 30GB hard disk, which can store up to 11 hours in 5Mbps Long Play mode. Even in the special super-quality XP mode, which involves a stunning 15 Mbps, the hard disk can hold up to 4 hours of HD video. The Smart HDD Protection system makes sure that your cherished memories are safe. In addition to the specially designed physical shock absorbers in the camcorder, the drive itself can detect the sudden acceleration of a fall and instantly auto-parks its heads, preventing them or the platters from being damaged by the impact. Better still, if you are filming, the camera will buffer the stream until the camera is stable and operational again. Do you want to keep your footage on DVD?
