Continua la serie degli hard disk sata più veloci al mondo attualmente disponibili sul mercato consumer.
Dopo la serie da 150gb e il primo sata2 da 160gb Wd rilascia la nuova serie di hard disk chiamata ''velociraptor''.

The fastest SATA hard in the world?
21.04.2008 09:55 pm - For years, Western Digital's Raptor is the only SATA hard, with 10,000 revolutions per minute expired, and therefore the first choice for hardcore gamers.
What makes it so special? The Raptor is the only SATA drive on the market, the 10,000 revolutions per minute achieved - a speed that would otherwise only expensive server models with SCSI or SAS interface is reserved for other SATA drives are working with 5,400 to 7,200 rpm. This guarantees (besides a little intrusive noise) high transfer rates, and especially low access times, the only SSD drives surpass. In recent years, the Raptor, however, arg in distress, or at least their transfer rates were from the new generation of the plate competition surpassed: 76.3 MiByte read the Raptor in PCGH Test average per second, while Samsung Point F1 spin on 91 MiByte / s achieved. Moreover, Western Digital's classic with 150 (WD1500ADFD) or 160 gigabytes of capacity (OEM version WD1600ADFD) many simply too small. Time for a successor.
The fact that the Velociraptor WD3000GLFS, starting today, the successor of the Raptor compete, bigger is no surprise to anyone - but it will also lower: Interior submit it to 300 gigabytes (279 GiByte), it shrinks the outside of 3.5 to 2.5 inch . Thus, Western Digital especially the server market, which represents as many drives in close accommodate racks looking for. As notebook panel is the new but not, for this is with 15 millimeters too high - ordinary notebook hard disks come to only 9 millimeters. According to WD is the wheel diameter of current 10k disks anyway, but lower than that of traditional 3.5-inch drives, shrunken is especially the case format.
For the WD3000GLFS also in 3.5-inch bays fits, it is moved to an appropriate aluminum chassis ( "IcePAK"), who is also in the cooling helps: Up to 7 degrees Celsius, according to WD is the temperature difference between "naked" and embedded plate. Removing the Velociraptor you do not - at least, the manufacturers do not.
Performance Promise
10,000 rpm, 16 MiByte cache - the key read like in the predecessor, the acceleration of SATA Interfaces from 1.5 to 3.0 Gbit / s has little practical impact. The higher performance, the New therefore only by the higher data density on its two Plattern. And Western Digital promises much for the supposedly "fastest SATA disk of the Universe": The average reading speed to be about 100 MiByte / s rise, the access times by one or other millisecond decline - from 4.7 to 4.2 ms with reading , from 5.9 to 4.7 ms when writing.
Images and additional benchmarks can be found in the gallery. My readings can we still do not offer, but in the next few days we will have our test samples, and then immediately report how the Velociraptor actually proposes. Then they should, according to Western Digital already available - the dinosaur is not a paper tiger.
