Western Digital VelociRaptor WD1000DHTZ Review

Western Digital recently sent us its latest-generation VelociRaptor, a 1 TB update to what was already the fastest 3.5" disk drive available. Once again, it stymies the mechanical competition with significantly higher performance.

Benchmark Results: Sequential Data Rate And Interface Bandwidth

There is no faster hard disk. At a maximum read and write rate of 209.1 MB/s, the Western Digital VelociRaptor WD1000DHTZ surpasses all other mechanical 3.5” drives. We can verify the company's claim of a 25% performance gain over its predecessor. Actually, it's closer to 33%. Hitachi's Deskstar 7K4000 takes second place. At a maximum data rate of 163.7 MB/s, though, it is decisively beaten.

We measured minimum sequential read and write speeds of 114.7 MB/s for the WD1000DHTZ, which ensures plenty of throughput for demanding applications.

    The Velociraptor at this price is simply not workable for me and for most people. For the cost of 1TB and some money saved, one can buy a good 120GB SSD and a Seagate 3TB. Seagate 3TB is not in the charts but I bet it will be only 10% slower than Velociraptor. This solution smokes out Raptor as a boot device and nearly matches it as a storage device.

    Even on a standalone basis, for me Seagate 3TB at $145 and 85-90% of Raptor's performance makes more sense that Raptor 1TB at $300.

    WD is living in a fools' world if they think that the premium they are charging on normal hard disks (because of `shortages') will be extendable to Raptor.

    Did you test it without the heat sink ?
    What would be its temperature if you'd have done it ?
    Could it fit into a performance desktop replacement notebook like a M18x or a Clevo mobile workstation ?

    Where is the noise test? I bet anyone $1Million dollars, its louder than any SSD. :)

    Yes, its a fast drive. It is most likely the last Raptor to ever be made. For video work, a typical 5400~7200RPM 2~3TB HD will do just fine. Can buy two 2TB drives + a 120Gb SSD for a tad bit more money... and still have a much quieter running system.

    For the price you could get a 1TB drive and the Crucial Adrenaline 50GB and combo them for a 1TB+50GB SSD cache. Half the price and probably just as fast.

    Why would I want an SSD in a gaming system? I need bulk capacity and this offers it in a fast package.

    Damn that's a fast drive. Would make a great high performance scratch disk.

    The market for these drives has certainly shrunk in the past few years, and I doubt many enthusiasts and gamers would even consider buying one anymore. It's value is limited to those who need more performance out of their storage devices than your typical 7200RPM 3.5" drive can deliver. Production pros working with large volumes of high res assets and complex project files would probably see the most benefit from a drive like this.

    I'm just confused...what is this drive for? It would get absolutely destroyed by an OCZ Agility 3 240GB, which I've seen for $130, I think--$140 for sure.

    If you're doing something where you specifically need 1TB of data accessible quickly all the time, this may have a niche, but it's a VERY SMALL niche. Almost everyone would find better performance paring a 240GB SSD with a 1TB HDD, using up 60GB on Intel's SRT, and 180GB for the SSD to be used as usual (Windows, programs, +60GB for projects/scratch).

    Considering the 256GB Vertex 4 is at $165 and the 256GB M4 hits $150, I'm just completely puzzled by Western Digital throwing money into developing such a device.

    acyutaSeagate 3TB is not in the charts but I bet it will be only 10% slower than Velociraptor. This solution smokes out Raptor as a boot device and nearly matches it as a storage device.No, the raptor is actually quite a bit further ahead than that, especially in random i/o, where it has as much as a 2x performance lead on the 3/4TB Barracuda XT's. Even in sequential reads/writes (generally the performance strong point of 7200RPM drives) it still has around a 50% performance advantage.

    The enthusiasts already have SSD's for at least their boot drive (or the whole system like me), a few might consider those for "bulk" storage drives but beside that i doubt its much market for the drive sadly. It don't no matter how impressive it is as a mechanical drive because it cannot compete with the SSD's. Still remember the first raptor, darn was it fast compared to the HDD's of that time before the SSD's came and change everything.
