Western Digital Raptor

from Wikipedia, the free encyclopedia
Western Digital WD740

The Western Digital Raptor (often simply called the WD Raptor ) was a series of high-performance hard drives manufactured by the Western Digital company. The drive took the niche market for enthusiasts, workstations and small servers. Traditionally, the majority of server hard disks are connected to a SCSI or SAS interface due to their advantages in performance and reliability , whereas the Raptor hard disks use SATA.

Although it appeared as an enterprise-class drive , it won enthusiastic favor because the Raptor was able to reach speeds normally only possible with more expensive server drives. The use of the SATA interface meant that it could easily be used on all modern motherboards at the time without having to buy separate (and often expensive) controller cards. In addition, the integration of the first models was made even easier by using a standard 4-pin Molex power connector in addition to the standard SATA port.

They presented this drive several series, with 10,000 min -1 worked and provided in each case larger capacities. Despite the production and further development of this disk from 2003 to 2015, there were no comparable SATA drives on the market. With the advent of solid-state drives , this hard drive became less and less important.

Models

WD360 (EL36)

In 2003, Western Digital released the first incarnation of the Raptor series: The WD360GD.

Presented with a capacity of 37 GB on a single disk and a Serial ATA interface, it was the first ATA hard disk with a spindle speed of 10,000 revolutions per minute . Like many early SATA drives, the Raptor wasn't a true SATA drive as it was actually a PATA drive using a Marvell 88i8030C interface bridge chip. However, this fact has not reduced performance. WD360GD Raptor hard drives use the 3.3 V of the Serial ATA power supply connection . There is no need to use a SATA power connector as it is underutilized.

WD740 (EL74)

The second generation of the Raptor was introduced in early 2004, with two platters for 74 GB of storage. In contrast to its predecessor, the WD740GD did not have a ball bearing that supported the rotating plates, but used fluid dynamic bearings . This allows the new Raptor, a noise level equivalent to that of a quieter drive at 7200 min -1 to come.

WD1500 (EL150)

Western Digital's third generation Raptor was released in January 2006. It had two 75 GB hard disks (for a total of 150 GB) and an extended system of native command queuing . At the same time, the Raptor X was released with 150 GB. It had the same specification as the standard Raptor, but with a window in the lid covered with acrylic glass and the label on the underside, whereby the window reveals the read / write heads and a section of the data disks so that you can watch the hard drive while working .

WD3000 (VR150M)

An early edition WD3000

The fourth generation of the Raptor by Western Digital was announced in April 2008. From now on the drive will be called VelociRaptor . In contrast to the Raptor, the VelociRaptor was a 2.5 "drive and in the first generation had up to 2 disks with 150 GB each. It was mounted on the IcePack heat sink, which was converted from the actual 2.5" drive into a 3 .5 "drive. In addition, the volume and power consumption of a conventional hard disk with 7200 revolutions per minute were much closer. From now on there was no longer a 4-pin Molex connector. Initially, the models with the ending GLFS were criticized, since the IcePack frame (see photo) made the drive not backplane compatible, so that the drive could not be installed in hot-swap removable frames. Therefore, the IcePack frame was revised and the new models had the ending HLFS. This revised frame remained in In addition, there were the BLFS models, which did not have an IcePack frame and were intended for blade servers . Removing an IcePack frame destroyed a Gara ntiesiegel. In addition, these 15 mm drives are too thick for notebooks and the power consumption did not allow them to be used. Shortly after its introduction, there was a version with a complete Plexiglas cover, but very few models were produced in this version.

WD6000 (VR200M)

The fifth generation of the Raptor was announced by Western Digital in April 2010. The data density was increased and the SATA interface was expanded to 6Gbps. Like its predecessor, this drive was marketed as a 3.5 "version as well as a 2.5" version. The endings of the names of these plates were HLHX (3.5 ") and BLHX (2.5"). Each platter could hold up to 200GB, the largest model WD6000HLHX of this generation had 3 of these platters. Other well-known representatives were the 2-plate WD3000HLHX and the 1-plate WD1500HLHX. But other sizes were also built, such as B. the WD1600HLHX with just 160 GB or the WD4500HLHX with 450 GB.

WD1000 (VR333M)

Two Western Digital 1 TB VelociRaptors WD1000DHTZ

The sixth generation WD Raptor (or 3rd generation VelociRaptor) had a further increased data density and a capacity of up to 1 TB (WD1000DHTZ). It was presented in April 2012. The WD1000DHTZ model had 3 disks, each with 333 GB. The other models of this generation had disks with exactly 250 GB installed.

Corresponding models from this generation (with the ending HHTZ) were: WD5000HHTZ (500 GB) and WD2500HHTZ (250 GB)

The 2.5 "versions had the suffix BHTZ for the models with 250 GB per disk, and CHTZ for the model with 333 GB per disk. In contrast to the predecessor, all models in this series had a 64 MB buffer instead of 32 MB the VR200M and a sector size of 4096 bytes, advanced format. In addition, the volume and power consumption could also be reduced while the performance of the drive was increased. Like all predecessors, the VR333 was offered with IcePack, the 2.5 "versions only released towards the end of 2013. While the data transfer rate increased significantly, the access time did not improve significantly.
