Description:
The exploding growth of enterprise data storage puts tremendous pressure on IT managers, who must accommodate ever-greater volume with ever-tighter budgets. This increased need for enterprise storage, coupled with the decline in IT budgets, creates a need for reliable, low-cost solutions. Enter Serial ATA (SATA), a new interface developed with enterprise storage in mind. Some hard drive companies design desktop-class hard drives with the SATA interface, but WD is going one better. To meet the demands of enterprise storage, Western Digital is the only company to combine an enterprise-class hard drive with the SATA interface to meet all the demands of the enterprise environment—reliability, performance, and reduced cost.
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 up to 30 percent less cost than Parallel SCSI drives.
WD RAPTOR PRODUCT BENEFITS
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 up to a third lower than Parallel SCSI enterprise hard drives.

Quote
I've worked with 4 different companies in the past two years as a technician (between moving from Edmonton to Calgary and finding a company that makes me personally the happiest) and each of them sold tons of Raptors. Looking at the return/RMA history, these drives fail very rarely - I'd go so far as to say you may have some issues with your power supply or something that killed both of your drives. I have no reservations about putting these drives in RAID0 and trust my data to both drives. I'd agree with you that WD had a bad run of IDE hard drives when the 120JB's first came out but overall they have a decent product. I hold firm that the Raptors are the best hard drives on the market though
