The WD Red 4TB offers capabilities for all customers with one-bay to five-bay NAS units. With a 64MB cache, and with its Intellipower low power spindle, the Red family is sure to meet your storage needs. The Intellipower technology for this WD Red 4TB is important, as its drives in this portion of the market experience continuous 24/7 use and are designed to require low levels of power.

Red disc storage offers more memory than competitor brands with the same size and interface. The My Cloud brand features 1TB, 2TB, and 3TB models as well. But the 4TB maximum capacity is available only for Red discs. Perhaps one of the most notable features available with this Red 4TB drive is WD’s Intellipower low power spindle. Low voltage will allow for significantly reduced consumption–a necessity when it comes to these drives that constantly run 24*7.

Hard drives are more expensive than they used to be, and for most of us the main consideration should be warranty and reliability.

Originally published on Careerizen.com when you compare the WD Red to other drives in general, performance is not as important of a factor because its manufacturer provides quoted transfer rates.

A WD Red drive is equipped with features to improve the performance and reliability of the device. 3D Active Balance Plus technology, a dual-plane balance control that reduces vibration and improves in overall performance and reliability by reducing deterioration on internal components. The WD Red 4TB HDD is specifically designed for NAS use with the latest NASware firmware. Not only do these drives deliver up to an impressive 190TB workload per year, but they also have reduced noise and power consumption as well as a spectrum of capacity options from 1TB to 10TB.

Design and Build

The WD Red 4TB includes the same design as the smaller 3TB model. It features six screws near the top of the drive’s case, whereas there are just four on the 3TB model.

WD Red HDDs offer a solid metal construction, standard power and SATA connectors on the outside of the appliance, and require four screws to remove the circuit board ##

The circuit board includes thermal pads for passive cooling of inner components.

The WD Red 4TB HDD utilizes the Marvell 88i9446-NDB2 controller together with 64MB of DRAM cache from the SKhynix H5PS5162GFA.

In the first work load, we measured an extended sample of random 4k performance with 100% write and 100% read activity. The WD Red 4TB scored 107 IOPS read and 137 IOPS write, placing it in the center of the distribution of results and notably outperforming its predecessor (the Red 3TB).

The WD Red 4 TB drive again landed in the center slot of our latency table.

The Red 4TB’s read and write latencies place it solidly in the middle among similar devices.

Charting standard deviation illustrates that the WD Red 4TB is competitive among large HDDs suitable for NAS applications.

In the following benchmarks, we have mixed workload profiles that can be scaled across 2 threads and 2 queue depth to 16 threads and 16 queue. The WD Red 4TB generally performed near the middle of its comparables in this 8k 70/30 test, with strong performance for two threads and a relatively deep queue.

The WD Red 4TB had a lot in common with the Seagate Constellation CS and WD Se 4TB.

Apart from a jump in maximum latency at two threads and high queue depths, the same as 4TB WD Red achieves high throughput, the 4TB Red takes about average performance through all 8K maximum latency. However, at the best workloads its performance is closer to that of the Constellation CS 4TB and Se 4TB than it is to other comparable models.

The WD Red 4TB surpasses the other items in regards to 8K benchmarking, but does not supplant either of the Seagate NAS or 3 TB models.

In the 128k test—a large sequential benchmark that measures data throughput for a drive with 100% write and 100% read activity—the Red 4TB performs as well as its 3TB sibling, though it has slightly better sequential throughput in both read and write operations.

The File Server profile puts the drives under a varying workload with a thread and queue count that scales from 2T/2Q up to 16T/16Q. The WD Red again exhibits high performance with two threads and deep queues, but otherwise remains at the median position.

However, in the file server average latency evaluation, the WD Red 4TB was not as impressive.

In addition to strong performance in low thread and low queue scenarios, the Red 4TB maintains its middle ranking through the entire maximum latency benchmark.

The deviation chart further emphasizes the strong performance at a thread count of two and queue of sixteen. Otherwise, it will not stand out among comparables but consistently outperforms the Seagate NAS 4TB and the Red 3TB.

The Net Server workload is made up of 100% read activities across our selection of threads and queue depths. The Red 4TB performed well in comparison to the Seagate NAS 4TB, WD Red 3TB, but not as good as the Constellation CS 3TB or Seagate SE4 TB

The performance of the Red 4TB beats out the other NAS-tuned drives in the net server benchmark.

The WD Red 4TB put in a regular performance, but it was weak on the default two-thread web server during the max latency test.

In our latest benchmarks, we found the Ridata Net Server to offer much better performance than the Seagate NAS and smaller Red drives.

Synology DiskStation DS1513+ Performance

In half of this review, we compare the performance of both the new 3.5 and 2.5 inch WD Red HDDs with RAID 5 configurations inside StorageReview’s Synology DS1513+. We can observe the performance of a 50GB test sample size on each storage array we created by leveraging SMB/CIFS shares.

The Western Digital Red 4TB and 2.5-inch Western Digital Red 1TB both showed a slight increase in performance when compared to the 3TB version of WD’s Red, while still not quite matching its competitor Seagate NAS 4 TB HDD. The brand new 1TB WD Red offered the fastest read performance in our group, but it had slower write performance than some of its competitors.

The new WD Red 4TB and 1 TB drive utilize a revamped head positioning system to combat stuttering.

Comparing performance, the 1TB and 4TB WD Red both came in near the top of peak read latency, with the 2.5-inch models coming in at bottom end due to higher write latency.

The 1TB WD Red ranked near the top of latency consistency, but at came in last when it came to write performance.

In our next test, we look at how performance scales from 2T/2Q up to 16T/16Q in a mixed 8K 70/30 workload. The drive which delivered the very best throughput for this system was RAID5 inside of a Synology NAS when configured with one disk. Comparing first and second generation Red HDDs, the 4TB model does offer some gains over the 3TB version according to workload intensity. It is slotting among other models of 1TB and 2.5 TB that offers its benefits.

Neither the 1TB WD Red nor 4TB Seagate NAS could beat out the 4TB WD Red or 4TB Seagate NAS in our 8K 70/30 test, with all of them basically ranking neck-and-neck.

Our 8K 70/30 test showed a lot of variance in performance across our different thread and queue levels.

We modified our standard deviation test to increase simulated system loads. The 1TB 2.5 Red, previous-generation 3TB 3.5 Red and 2MB VR were the best performers in these tests with a little more consistency than other models,

Performing 8K sequential operations, we found WD’s 4TB and 1TB Red models performing similarly to the 3TB version in read speeds but with faster write speeds. The Seagate 4TB NAS offered both higher write and read throughput in this test.

Our last test, which measured the performance of larger blocks of data being written to or read from the disk, showed that both 1TB and 4TB WD Red led this group. The two 2.5 model offered the best sequential read performance by a slim margin, but when you compare write speed it came in third place. The brand new 4TB WD Red though came in with the next highest read speed and best-in-class write performance.

The WD Red Disk drives were designed to answer the question “Which hard disk do I install in my NAS?”. The answer is this one, because of its constant performance in benchmarks. It is perfect for people who own and run their own NAS server. Seagate NAS 4TB, WD Red 3TB and Seagate Constellation CS 3TB HDDs performed better than the WD Se in single-drive benchmarks.
