WD Black 6TB HDD Review

 

Even with the rise of solid-state drives, traditional high-speed hard-disk drives still have a place in the market especially in the entry-level and mid-range markets. So it isn’t a surprise that WD has released a new and higher capacity, higher performance version of its Black series HDD to replace the 4TB variant from a few years back. The new variant features a larger capacity at 6TB, a larger cache size, and newer technologies to provide high-speed storage performance for enthusiasts, professionals, and gamers.

The new WD Black 6TB drive features the same 3.5-inch form factor and look as its predecessor with its aluminum and plastic casing coupled with the standard WD product label on top with the company’s logo as well as all the important information about the drive including its capacity, serial number, model number, and more.  It also uses the same SATA 6Gbps interface making it compatible with most desktop systems and enclosures.

On the inside, aside from its increased storage capacity, the WD Black features double the cache of its predecessor at 128MB giving it a rated sustained data-transfer rates of up to 218MB/s, an improvement over the 194MB/s sustained data-transfer rates of its predecessor. Additionally, the WD Black 6TB also comes with WD’s StableTrac and Dynamic Cache Technology which improves data tracking accuracy in spite of increased vibrations from other components and enhances caching algorithms on the fly, respectively.

We ran the WD Black 6TB through ATTO Disk Benchmark and CrystalDiskMark and results were a mixed bag. The results of our ATTO Disk Benchmark showed that the WD Black 6TB was able to beat out both the WD Blue HDD as well as the WD Blue SSHD in both the read and write tests but still performed way below our HyperX Fury SSD in both tests.

In CrystalDiskMark, the WD Black easily outperformed all of the other drives in the Sequential Read and Write tests but the results varied when it came to the 4K Read and Write tests as while it was able to outperform both the WD Blue HDD and WD Blue SSHD in the 4K Read test and the WD Blue HDD in the 4K Write test, it scored lower in the 4K Read tests against our HyperX Fury SSD and the 4K Write tests against both the WD Blue SSHD and our HyperX Fury SSD.

Conclusion

{rating}

The new WD Black 6TB successfully improves on its predecessor’s strengths with better performance due to its larger cache and Dynamic Cache technology. In spite performing lower than an SSD, the WD Black 6TB is still impressive and when coupled with its great price to capacity ratio, it’s a great option for gamers, enthusiasts, and professionals looking for a high capacity drive with the performance to keep up with their high-demand applications.
