The Western Digital Caviar Special Edition 250GB internal hard drive is more than just a big disk. At nearly $400, the Caviar Special Edition commands a premium price per gigabyte, but you get what you pay for in this case.
The upgrade kit includes a parallel ATA/100 PCI controller card, a ribbon cable, and screws. The same upgrade kit is also available with 80GB, 120GB, 160GB, 180GB, and 200GB hard drives. Western Digital does not provide separate kits for Macs.
Two floppies hold drivers and installation/diagnostic utilities. Western Digital puts all of the essentials right under your eyes. The poster-size setup sheet, though not model specific, gracefully leads you through several possible installation scenarios, and an additional insert outlines the vagaries of the 137GB-drive size limit. The only glitch was that the jumper-setting diagram on our test drive contradicted the correct diagram on the install sheet.
Like the Maxtor Ultra 7200 series 200GB, the Caviar Special Edition scorched CNET Labs' hard drive benchmarks. It wasn't quite as fast off the mark as the Ultra 7200 series, but its record-setting sustained data transfer rates make it a sure bet for almost any common storage application.
