WD Red Pro 4TB Enterprise NAS HDD Review

128k Sequential Read/Write




We write to every LBA to highlight performance degradation from the outer to inner tracks of the drive. The drive begins with much higher speed on the outer tracks, and loses speed as it works inward. It required 7 ½ hours to write the entirety of the capacity of the drive, and a sequential read test following the same methodology results in nearly identical results.




128k sequential speed reflects the maximum sequential throughput of the SSD, and is indicative of performance in OLAP, batch processing, streaming, content delivery applications, and backup scenarios. Today's HDDs are increasingly used for sequential workloads as SSDs encroach upon the application space.


The WD Red Pro easily leads the test with 171 MB/s, distancing itself from the SE's average of 160 MB/s. The WD Red offers the lowest sequential read speed with 139 MB/s; the Seagate NAS HDD provides a staggered performance profile with an average of 163 MB/s at QD256.




The WD Red Pro offers the best overall latency during every segment of the test.




Sequential write performance is important in tasks such as caching, replication, HPC, and database logging. The WD Red Pro provides a leading 170 MB/s at QD256; the WD SE provides 160 MB/s, the WD Red provides 139 MB/s, and the Seagate NAS HDD provides 162 MB/s.




The WD Red Pro again provides the best latency performance during the measurement window.




The WD Red Pro continues to display its leading sequential performance in our mixed read/write workload testing.




The WD Red Pro continues to draw more power than the other solutions with an average of 9.64 watts.






The WD Red Pro offers 17 MB/s for read and write MB/s-per-watt.
