USB suplik bez externiho napajeni
zajimalo by me, zda-li existuji USB 2.0 supliky na HDD, ktere nevyzaduji externi napajeni.
premyslel jsem, jestli by neco takoveho neslo vyrobit napr. zapojenim vice USB konektoru, ze by se 1 pouzival jako datak+napajeni a ostatni jen jako napajeni.
mate zkusenosti

Existuje to, ale len na 2.5" disky. S 3.5" diskom nie je sanca - potrebuje aj 12V a navyse vela zerie.

se podivej na datasheety k 3,5" diskum a uvidis, ze maji kolem 10W
navic rainbow uz jasne rekl, ze je potreba 12V a ty na USB teda rozhodne nevycarujes
EDIT napriklad seagate B7200.7 ma 12,5W pri seeku

WD400BB: 5V...0.63A, 12V...0.35A a pri rozbehu to bude este viac. Navyse "vyrobu" 12V by si potreboval nejaku elektroniku, co ma dalsiu spotrebu.
