WD VelociRaptor 450GB 10000 RPM SATA Drive
The WD VelociRaptor WD4500HLHX is a 450GB 3.5-inch internal hard drive spinning at 10000 RPM with a 32MB cache and SATA 6.0Gb/s interface. It targets server environments and high-performance desktop workloads that demand fast mechanical storage. The bare-drive packaging suits system integrators and builders who install drives directly into chassis or backplanes.
IcePack Frame 2.5-Inch Drive in 3.5-Inch Carrier
The 2.5-inch mechanism sits inside an IcePack mounting frame that provides a backplane-ready 3.5-inch form factor for hot-swap bays and standard drive cages. The frame acts as a heatsink, helping the drive consume less idle power while maintaining similar active power to the previous generation. Enterprise-class construction targets 1.4 million hours MTBF for high duty-cycle reliability.
15 Percent Speed Gain Over Prior Generation
The SATA 6.0Gb/s interface combined with 32MB cache delivers up to 15 percent higher performance than the award-winning previous generation VelociRaptor. Capacities across the series reach 600GB, doubling the prior maximum. No cables, brackets or software utilities are included with the bare drive.

Questions about this item
What does the SATA 6.0Gb/s interface cap in practice?
The SATA 6.0Gb/s interface caps the maximum theoretical transfer rate at 6.0 Gb/s. Actual sustained throughput depends on the 10000 RPM platters and 32MB cache, but the interface itself will not exceed that ceiling.
What physical space does the 3.5" IcePack mounting frame require?
The drive uses a 2.5-inch mechanism inside a 3.5-inch IcePack frame, so it fits a standard 3.5-inch drive bay and uses standard SATA data and power connectors.
How is the bare drive installed, and what step is often missed?
Mount the 3.5-inch frame in the bay, connect SATA data and power cables, then initialise and format the 450GB volume in the OS. The step often missed is initialising the disk before formatting.
