The Ultrastar 2ES is IBM's entry-level 4.5 GB drive.
Entry-level does not necessarily mean low-cost, though, as the 2ES weighs in at a hefty
$500. The drive is conspicuously the only 5400 RPM drive in this roundup, with performance
to reflect its slow spindle speed. It posted the second-slowest Business WinMark 98 score
along with the third slowest High-End Winmark showing of the group. The drive's manual was
thorough and easy to follow. Even so, the Ultrastar 2ES' pokey performance combined with
its fairly high price make it a very hard recommendation. Users looking for an entry-level
SCSI drive would be better serviced by Quantum's Viking or Seagate's Hawk 4XL.

IBM's Ultrastar 2XP weighs in as the most expensive drive
in this roundup, an astonishing $800 in price. IBM provides a thorough multi-lingual
manual. One would infer top performance from this drive, especially in the light of IBM's
showing in the UltraATA drive roundup. The 2XP does indeed provide decent performance, but
nevertheless disappointed given the price. Seagate's Cheetah and Barracuda both bested the
Ultrastar 2XP in performance and both cost significantly less. This drive cannot be
recommended due to its lofty price.
