The U5's poor access time
leads it to a pounding in the seek-intensive IOMeter Workstation
Index (a normalized average of our Light, Medium, and Heavy
loads). Its score of 100.9 falls over 27% behind the IBM Deskstar 40GV
. Even a comparison against the Quantum Fireball lct15
, hardly a star in our IOMeter suite, shows the Quantum besting the Seagate by 12%.
