Let the hive mind of Engadget get that for you.
"I'm looking for a solid state drive, around 32 to 64GB, for use in my web server. The drive will contain my web sites and the operating system, either Windows Server 2008 R2 or Ubuntu. Large storage is handled by a separate RAID array, so capacity is not an issue. Rather, I am looking for the fastest, longest-lasting, and most reliable drive under $150 that is suitable to my application. Any thoughts? Thanks!"
The linked article completely ignores the most common use of the Combo disks -- households with children and a mixture of HD and SD equipment. It's almost as if the author wasn't aware that people with different needs and situations than himself exist. "If I don't need it, no one does" could well be the title of the article.
The Engadget blurb seems to also make a mistake. The current combo format (one format on either side) is NOT the same as the recently-approved dual-layer combo format, which has both formats on ONE side and is presumably no extra cost. And certainly no confusion, since all Toshiba players (or at least A2 and later) have a setting for which layer they play if they encounter such. Since the DVD Forum approved it, one has to believe that normal DVD players also play their version automatically.
The idea of the combo format is a good one, hobbled by the extra cost and the two-side confusion. If you eliminate those issues, what's not to like? Yet another thing HD can do and BD cannot.
