Das ist kein wirklich neues Feature, wie aus dem hier schon verlinkten WikipediaArtikel zu ersehen, sondern seit Jahren Bestandteil im ATA-Standard. Sollte somit jede Platte können.

Also ich hab die Platte seit ner Woche in meinen mbp und merke nix. Weder von gestiegener Wärme, noch Akkuunterschiede. Also von meiner Seite ist das teil ne absolute Kaufempflung..
Lauter ist sie nicht unbedingt, lediglich macht sie nen anderen Ton, etwas höhreres "rauschen". Aber im Vergleich zu meiner 120gb Fujitsu die vorher drin war, kein nenneswerter Unterschied.
Lediglich die Performance ist deutlich besser, und dort vor allem macht sich das in den Randomzugriffen bemerkbar (dank 7.200). Das sind auch die, auf die man schauen sollte. Selten ist es der Fall im Alltag (Außer beim Datenschieben ubers Netz), dass wirklich viel sequentiell zugegriffen wird, weshalb viele hier unnütze Werte vergleichen (aka Kona.. ).
Man schaue vorher:

Nachher:
http://xen.vccl.de/stuff/xbench_wd320.txt
Ca. das Doppelte im Randombereich..
wieso nur habe ich andere werte???
ärgerlich (für mich)
