Seagate Desktop SSHD ST4000DX001 4TB Review (Page 10 of 10)

Page 10 - Conclusion

Coming from a Seagate Laptop SSHD ST500LM000 500GB hard drive, I already knew what to expect from the Seagate Desktop SSHD ST4000DX001 4TB. What was unexpected, however, was its raw performance compared to other desktop hard drives. The Seagate Desktop SSHD was very competitive even in uncached mode. Once again, in PCMark 7, where we had the opportunity to see how the Desktop SSHD approach the problem with caching enabled, there was clearly a considerable amount of performance gain, once it "learns" what data to cache. This will definitely translate to real world speed improvements. As I have said in my Laptop SSHD review, while the Desktop SSHD -- even with cached data -- will not be as fast as a true SSD, the ST4000DX001 will no doubt be faster than a pure mechanical hard drive with no flash components in boot speed and application loading. That said, I think having an 8GB cache is a bit stingy, especially considering we are talking about a 4TB desktop drive here. The Seagate Desktop SSHD will be capable of keeping only a small amount of data in its flash memory; ask for a little more, and you are off the turbo. As a 3.5" hard drive, I do not believe it is unreasonable ask for a bigger cache, since there is not a whole lot of space or power consumption constraints, and flash memory is pretty cheap in 2015. That said, retailing for about $160 at press time, the Seagate Desktop SSHD ST4000DX001 4TB comes at a surprisingly good price. It commands a price premium of only $25 over a regular Seagate Desktop HDD with the same capacity, and is $40 cheaper than the new Western Digital Blue WD40E31X 4TB SSHD.
