Page 10 - Conclusion
When it comes to hard drives, Western Digital and Seagate has been great competitors in the last little while. In fact, in the end of my Seagate Desktop SSHD ST4000DX001 4TB review a few months ago, I have alluded to the Western Digital Blue SSHD WD40E31X 4TB, and guess what? Here we are today with both drives in our hands, with performance data collected for both hybrid drives. Based on the benchmark results, it is hard to define a clear winner. In uncached mode, Seagate's entry delivered better linear performance for better results in synthetic benchmarks compared to Western Digital's SSHD. Furthermore, its higher spindle speed -- 5900RPM versus WD Blue's 5400RPM -- gave it a slight advantage in PassMark PerformanceTest's advanced workload simulations. Seagate's HDD small file transfer rate is some of the best in the industry, and the ST4000DX001 was no exception. However, when it comes down to real world desktop workload tests, Western Digital's Blue SSHD WD40E31X 4TB started to flex its muscles. Not only did it hold its own against the Seagate Desktop SSHD in uncached mode, when caching kicked in, it either matched or considerably outperformed the Seagate in every test. Simply put, the ST4000DX001 is a better raw desktop drive, but the WD40E31X is a better SSHD. The WD40E31X is also about 20% more power efficient than the ST4000DX001, which is significant. My only complaint, like I have said in my Seagate Desktop SSHD review, is having 8GB of flash memory for a 4TB drive is a bit stingy in 2015. A cache miss means your SSHD is no better than a regular HDD. Retailing for $175 at press time, the Western Digital Blue SSHD is $25 more than its direct competitor from Seagate. But if power consumption is important to you, and you want something that performs better as an SSHD in regular desktop workloads, then the WD40E31X is the drive to buy.
