The linked spec doesn't talk about power loss, and I don't have time to read it all. But the way this article is written I read it as the spec requires handling it somewhere other than on the drive. Or phrased differently, the drive doesn't need caps to meet the standard; not that having caps is forbidden by it. That said I am curious what the standard is myself; is it just some sort of super journaling/etc, or moving power loss control up from individual drives to the drive array (eg the enclosure) as a whole.
If you read the datasheet in the link, there's a section that reads "an exclusive power loss data management feature that does not require supercapacitors." Not really any information that isn't already in the AT article. I'm also curious what they're using instead of supercaps.

"...as well as a special power loss data management feature that does not use supercapacitors."Why disallow super-capacitors?
