Storage Review heeft de IBM Deskstar 25GP gereviewed. De 25GP is het 25GB model uit de oude 5400rpm serie van IBM:
As expected, the Deskstar 25GP performs quite similarly to the latest Caviar from WD. This does mean, of course, that the 25GP ranks right up there with the WD disk as the fastest 5400rpm drive currently available. Performance differences between the 5400rpm IBM and WD units were even tighter than the correlation between the companies' 7200rpm drives. Differences in the Business and High-End Disk WinMark tests running under both Windows 95 and Windows NT were held within a negligible 1%.
