For the DRX-S90U's software bundle, Sony has turned to Nero. The CD that comes with the drive contains a stripped down version of the Nero 10 Essentials suite which includes Nero Express, Nero MediaHub, and Nero CoverDesigner.

Nero Express - With Nero Express, Nero has taken the features and performance people have come to expect from Nero Burning Rom and combined them with a user friendly interface. Designed to maximize ease-of-use, Nero Express gives users the ability to quickly and easily burn audio, data and video to CD or DVD.

Nero MediaHub - Nero MediaHub lets you conveniently play back your music files, plus manage and create playlists. It lets you easily create cinema-style videos and photo slide shows with integrated movie themes, plus conveniently manage your multimedia projects. You can play back your photos and videos right on your PC with all the convenience of a built-in DVD player.

Nero CoverDesigner - Nero CoverDesigner is a powerful application for creating custom cover elements such as booklets, inlays and labels. Nero CoverDesigner supports cover elements for a wide range of disc types, such as CD jewel cases, DVD cases, multi-boxes, maxi CDs, slim packs, business cards and more. Nero CoverDesigner also supports LightScribe and Labelflash recorders, which you can use to print labels directly on compatible media.

While small in size, Sony's new portable DVD writer isn't short on features. Along with a great looking design, the DRX-S90U offers some of the fastest reading and writing speeds available on a portable unit. The drive is capable of 8x DVD±R, 8x DVD+RW, 6x DVD-RW, 6x DVD±R DL and 5x DVD-RAM writing speeds and a maximum DVD read speed of 8x. The DRX-S90U also includes features like Power-Burn buffer underrun protection and built-in dual USB cables that provide power for the drive. Unfortunately, it lacks bitsetting support for single layer DVD+R and DVD+RW media. Even then, the Sony DRX-S90U scores a solid 8 out of 10 for its features.
