With a Stordigital tower duplicator fitted with an optional hard drive, you have the convenience of up to 2TB of on-board storage. This allows you to save your important masters digitally, to be recalled on-demand without having to search for a delicate CD/DVD disc that is easily scratched, smeared, or lost. In addition, an internal hard drive fitted in your duplicator should enable you to safely burn your discs at a faster burn-rate than using the DVD ROM drive as your source. This is because the moving parts in the Reader are more prone to throwing-up errors than the more solid hard drive. This means a higher output of correctly duplicated discs and less rejected ones.
