The VelociRaptor Doubles In Capacity

Western Digital (WD) today announced its first new enthusiast-oriented VelociRaptor hard drive (HDD) in nearly two years with the launch of the 450GB and 600GB capacity drives this morning. These new drives not only double the capacity available for this 10,000 RPM enterprise storage drives, but they also introduce support of the SATA 6Gbps interface and increase the drives' cache from 16MB to 32MB!  Thanks to these specification improvements the VelociRaptor has doubled in storage space and has gained roughly 15% in overall drive performance compared to the VelociRaptor WD3000GLFS 300GB hard drive that we reviewed in April 2008 here.  To make top it all off we are told that the new drives consume no more power than the previous generation WD VelociRaptor! Today, we have the WD VelociRaptor 600GB (WD6000HLHX) IcePack Hard Drive and we'll be taking an in-depth look at the drive's features and the performance of the drive compared to the previous generation VelociRaptor HDD and other popular SSDs.

WD VelociRaptor 600GB WD6000HLHX Hard Drive

The VelociRaptor has always been aimed at high-performance PC enthusiasts who demand the ultimate SATA drive. Western Digital has built the VelociRaptor hard drive with enterprise-class mechanics that provide 24x7 durability under high-performance demands, and as a result they are rated at 1.4 million hours Mean Time Between Failures (MTBF). The WD VelociRaptor drive is also available in the IcePack enclosure, a 3.5-inch mounting frame with a built-in heat sink – a factory customization that fits the drive into a standard 3.5-inch system bay and doubles as a hard drive cooler as well.  If you remove it from the IcePack housing the drive is only 2.5-inches in width, but WD only sells the 2.5-inch bare drives to OEM customers. Don't think about stuffing one of these in a netbook or notebook, though, as the 10,000 RPM drives feature a 15mm z-height, which make them too thick to fit in a standard notebook storage drive bay. The drive pictures above and the one we are reviewing today will be using the WD IcePack.

WD VelociRaptors SATA 6Gbps drives are available in two capacities:

The 2.5-inch WD VelociRaptor is enclosed in a backplane-ready 3.5-inch enterprise-class mounting frame with a built-in heat sink that keeps the drive cooler when installed in any chassis that has decent airflow. The new 450GB and 600GB VelociRaptor drives feature a brand new 3-platter design with 200GB per platter. The previous generation VelociRaptors used a two platter design with a pair of 150GB platters. This new 3-platter design, along with the newly added SATA 6GB/s interface support, is how WD was able to get the data transfer rate (buffer to disk) up from 128 MB/sec on the 300GB model to 145MB/sec on the new 600GB model that we are looking at here today.

WD VelociRaptor Product Specifications:

Here is a better look at the SATA 6Gbps header and the SATA power connector on the VelociRaptor series. The SATA 6 Gb/s storage interface is backwards-compatible with SATA 3 Gb/s interfaces, so no worries about that. For maximum performance you will want to run the VelociRaptor 0 in ‘AHCI’ mode in the BIOS and on a SATA 6 GB/s controller.

WD VelociRaptor 600GB WD6000HLHX Hard Drive Specifications

The overall performance and features of the VelociRaptor remain unchanged and the only thing we haven't mentioned yet is that the head load and unload cycles of the drive are rated at 600,000.  The drives come with a 5-year warranty just like the previous generation! Let's move on to performance testing to see how the drive performs!

The Test System

SATA 6GBps Marvell 91xx SSD Test System

Before we look at the numbers, here is a brief glance at the test system that was used. All testing was done on a fresh install of Windows 7 Ultimate 64-bit. All benchmarks were completed on the desktop with no other software programs running. The Intel Core i7 test system was run in triple-channel memory mode at 1600MHz with 8-8-8-24 memory timings. The ASUS P6X58D Premium motherboard was run using all the latest drives and BIOS 0702. The ASUS P6X58D Premium motherboard uses the Intel ICH10R south bridge chipset, which we used to run our 'boot drive'.  The boot drive used in our test system was an Intel X25-V 40GB model with TRIM enabled. We then used the Marvell 9123 PCIe SATA 6Gbps controller that is on the motherboard to test the SSDs and HDDs that are used in the benchmark charts. All of the SSDs and HDDs were tested in a fresh, out of the box (FOB) state and the system had the latest firmware installed on it when testing was done.

SATA 6GBps Marvell 91xx 1031 Driver

The Marvell 9123 SATA 6G Controller was tested using driver version, or 1034 for short.  This driver is said to be the first Marvell driver able to pass the TRIM command from Windows to the drives.

Final Thoughts and Conclusions

The Western Digital VelociRaptor 600GB hard drive (WD6000HLHX) has been rumored for many months now and it is great to finally see the drive come to market. The drive doesn't bring many new features other than SATA 6Gbps and the larger 32MB cache to the table, but WD has doubled the capacity of this 10,000 RPM drive series and did manage to boost performance as advertised. In fact, we noticed more than a 15% performance increase in some benchmarks, which was great to see. It was also interesting to see how large the performance gap has come between hard drives and solid-state drives. The VelociRaptor series is an enthusiast class product and is ideal for those PC users who don't want to jump into the SSD market right now. The new 450GB and 600GB VelociRaptors would also make for great secondary storage drives to those that have an SSD as their primary storage drive.

Western Digital VelociRaptor hard drives are available through select distributors and resellers starting today. All of the WD VelociRaptor drives come backed by WD’s five-year limited warranty. Manufacturer's Suggested Retail Price (MSRP) for the WD VelociRaptor 450 GB (model WD4500HLHX) is $299 USD and the 600 GB (model WD6000HLHX) is $329 USD.

That breaks down into something like this when it comes to cost per gigabyte:

When it comes to pricing, the new VelociRaptors actually cost less per gigabyte than the previous generation, so there really isn't much to complain about with the new VelociRaptors! The capacity has doubled, the performance has increased and the price per GB has decreased by nearly 18 percent! If you are looking to buy a hard drive and want a SATA 6Gbps drive with performance as a key feature then be sure to give the new 450GB and 600GB VelociRaptors a really good look!
