- Serial ATA150, 150MB/sec
- 8MB cache will have better proformance than 2MB like Maxtor,
IBM, Seagate HDDs
- 10K RPM, and only 5.2ms Average read time compare to Seagate
SATA 80GB and 120GB have 8.5ms
- WD provides 5-years warranty. Others only provide 1-year
warranty.
- Built for speed, the WD Raptor has 10,000 RPM rotational
disk speed and 5.2 ms average data seek times.
- Built for reliability, it has a rugged, enterprise-class
mechanical platform with high-end bearings and actuator.
- Built to last, this Enterprise SATA (ESATA) hard drive
is made for years of high-performance operation around the
clock. MTBF has been calculated at 1.2 million hours.
- Built with a backing, WD Raptor ESATA hard drives carry
Western Digital's five-year warranty.
- Built for value, WD Raptor is priced nearly a third lower
than Parallel SCSI enterprise hard drives.
A NEW BREED OF HARD DRIVE:
Serial ATA is poised to replace Parallel SCSI in the mid-range,
but only if there's a drive that can meet the performance
and reliability requirements of that market. That drive is
the WD Raptor! The WD Raptor is a new class of hard drive
that matches SCSI performance and reliability and provides
simplified connectivity, all at 30 percent less cost than
Parallel SCSI drives.
