10,000rpm Serial ATA hard disk

Western Digital has just released a 10,000rpm (revolutions per minute) 36GB hard disk drive. The Raptor (WD360GD) is the first 10,000rpm drive to hit the market that features the Serial ATA interface and an 8MB disk cache.

Featuring a rugged exterior, the Raptor is noticeably heavier than its 7200rpm counterparts. A newer Serial ATA power plug is used due to the lower power consumption of Serial ATA hard disks. A legacy four-pin Molex connector is also present, so a power supply upgrade or molex adapter is not needed to get the drive running.

We tested the Raptor against a 7200rpm Seagate Barracuda hard disk using the Parallel ATA interface, with a program called HD Tach 2.61 (www.tcdlabs.com/hdtach.htm). Both hard disks were tested on a system that featured a Pentium 4 3GHz, Gigabyte 8PENXP motherboard, 512MB of DDR400 Corsair memory, and a GeForce4 Ti 4200 graphics adapter.

As the test results indicate (refer to table), the Raptor hard disk falls between the Parallel ATA 7200rpm drives and the SCSI 10,000rpm drives. Early adopters and performance enthusiasts would benefit most from this drive.

Brother QL-820NWB Professional Label Printer

It’s easy to set up, it’s compact and quiet when printing and to top if off, the print quality is excellent. This is hands down the best printer I’ve used for printing labels.

Brainstorming, innovation, problem solving, and negotiation have all become much more productive and valuable if people can easily collaborate in real time with minimal friction.

The print quality also does not disappoint, it’s clear, bold, doesn’t smudge and the text is perfectly sized.
