Comment low energy efficiency? (Score 1) 603

by marmusa (#26210789) Attached to: EEStor Issued a Patent For Its Supercapacitor
Vague memories from my physics degree suggest that as much energy is wasted while charging the capacitor as is actually stored in it. See eg. http://en.wikipedia.org/wiki/Capacitor#Power_dissipation. Does this mean that this system could only ever be 50% efficient? Does anyone know whether similar physics applies to battery systems?

Which OS Performs Best With SSDs? 255

Posted by CmdrTaco from the io-io-it's-off-to-work-we-go dept.
Lucas123 writes "Linux, Vista and Mac OS perform differently with solid state disks. While all of them work well with SSDs, as they write data more efficiently or run fewer applications in the background than XP, surprisingly Windows 2000 appears to be the winner when it comes to performance. However, no OS has yet been optimized to work with SSDs. This lost opportunity is one Microsoft plans to address with Windows 7; Apple, too, is likely to upgrade its platform soon for better SSD performance."
