The Western Digital Black is a symbol of storage performance. Even if we go back to the days before solid state was king, the drive you wanted in your system was, next to the Raptor, a WD Black.

Now that we have reached what seems to be peak capacity for the time being, with both Seagate and WD having reached 4TB across their entire product lineup (minus the WD Blue), you may wonder what is next. Well, if you are Western Digital, you increase the performance of your flagship product.

The WD4003FZEX is the second generation, 4TB high performance solution from Western Digital. With this drive comes increased performance using a new High Resolution Controller and dual-core processor to increase drive precision and performance. Additionally, WD has added Vibration Control Technology to compliment StableTrac, resulting in more accurate tracking during read/write operations.

Let's dive in now and take a close look at it.

Specifications, Pricing and Availability


Looking at the specifications above, you will notice the new WD4003FZEX placed next to the first generation FAEX drive. Running down the specs list, we find the drive using the SATA 6 GB/s interface with a capacity of 4TB.

In addition to the new technologies we mentioned above, Advanced Format capability was added to this second gen drive as well. Moving on, we find a slight increase in spec'd transfers rates, with the new drive reaching 171 MB/s over the previous 154 MB/s.

The WD Black still enjoys a nice 64MB cache and its 7200-RPM spindle speed across five 800GB platters. Additionally, the load/unload cycles have stayed consistent at 300,000. The bit-error rate stands at 10e14, along with an industry leading five-year warranty.

The WD Black is available in four capacities ranging from 1TB to the 4TB, which we have in house today. Pricing of the 1TB model is a set at $89.99 with the 2TB, 3TB and 4TB models coming in at $159.99, $209.99 and $269.99, respectively.
