Storage Review vond het nodig om een review te posten van de 37Gig dikke IBM Deskstar 37GP UDMA/66 harddisk. De schijf draait op slechts 5400rpm en moet het in deze performance categorie wat betreft snelheid afleggen tegen de Western Digital 205AA:
An interesting comparison arises when we set the Deskstar 37GP against WD's Caviar WD205AA. Readers may recall that the specs and performance between the Deskstar 25GP and the Caviar AC420400 were quite similar. In this successive generation, however, we're seeing some differences. IBM has packed more data per platter on the 37GP than WD did with the WD205AA. On the flip side, WD states that its incorporated a variety of proprietary improvements in the firmware side that make the WD205AA a drive all their own.
A look at the transfer rates delivered by low-level WinBench 99 tests show that while the IBM packs more data per platter, the two drives sport virtually the same transfer rate on the outer tracks. When the test gets to the inner track, however, the WD proves to be slightly faster. It seems IBM's improved GB/platter arises from more densly packed tracks rather than squeezing in more data per track.
