Design
When you're designing an external optical drive, you need to keep a couple of things in mind. Being external, it needs to be relatively small; people buy external drives for portability, after all. It also needs to be reasonably robust; unlike an internal drive, an external drive is likely to undergo more knocks than average. Sony's slim DRX-S70U drive addresses both of these areas neatly. It's a slim (135.5x19x154mm) and light (440g) drive in a rigid black metal casing. As such, it should slip into most notebook bags without creating too much of a bulge -- if it weren't for the AC power adaptor and USB 2.0 cable, which expand its bag size noticeably.
Features
The DRX-S70U is a combo DVD/CD burner with support for every format you'd care to throw into it, from humble CD to DVD+R DL. Rated write speeds are 8x (DVD+/-R), 8x (DVD+RW), 6x (DVD-RW) 4x (DVD+/- R DL) and 24x (CD/CD-RW).
The DRX-S70U requires AC power to operate and a 5.2V AC adaptor is provided, along with a short length of USB cable. On the software side, Sony provides Nero 7 Essentials for Windows. That gives you the very cut down Nero 7 suite, substituting Nero Express for Nero Burning ROM, and the lower specification "essentials" versions of Nero Vision, Showtime and MediaHome. The notes on the drive declare it to be Mac compatible, although no Mac software is provided with the drive itself.
Performance
The drive within the DRX-S70U was revealed to be an Optiarc AD7540A drive -- Optiarc is a joint venture between Sony and NEC -- and basic testing revealed it to run at at an average of 5.3x on a 4.7GB DVD-R disc, a touch lower than the stated 8x that Sony states it's capable of. DVD discs created with the DRX-S70U took around twelve minutes to complete in our tests.
It's worth noting that the cut-down Nero utilities will cover most basic burning tasks, but those who hanker for control will need a more robust package -- perhaps the full Nero suite, or Roxio's Easy Media Creator 10, for example.
There's definitely a market for drives like the DRX-S70U, whether you're enhancing the abilities of a system that doesn't have a drive or just keeping an older notebook with a defunct drive in service. The DRX-S70U isn't the cheapest external drive we've ever seen, but it's reasonably priced given the solid build quality.

Dud DVD players aren't that common, so the people who would buy this product need this as their primary DVD. Macbook Air and EeePC users for example. Oh, that right, this is for PC users only...
Pros: Nice product
Cons: No market without drivers

Why would Sony want to support MAC for, considering PC's are more popular. As for AC Adapter, well common sense is you cant fit a power supply in a drive that thin, and USB power wouldnt be enough to power a burner.
