We took a look at both of WD’s 4TB hard drive options in the past month, so it’s a great time to get some Seagate action going. The Constellation ES.3 competes with WD’s RE in the enterprise space, but it brings an interesting feature to the table: a 128MB cache. So let’s give the the drive a good test and see if it can topple the RE drive we raved over.
Synthetic: PCMark 7
Futuremark’s PCMark benchmarking suite should need no introduction – it’s been a staple of PC benchmarking for the better half of a decade. PCMark offers a range of tests to gauge every aspect of a computer’s performance and presents it in a simple final result. Thankfully, it also breaks down the overall score with individual subsystem scores (such as Memory, Storage, et cetera) in addition to providing individual test results.
As we’re not too concerned with the performance of the PC as a whole, for our testing here we deselect all default tests and run only the “Secondary Storage” suite, with the hard drive in question as the chosen drive. Tests in this suite range from the loading of applications, running a Windows Defender scan, editing video, gaming and more.
The results seen here reaffirm the idea that Seagate’s drive must use (in all likeliness) 1TB platters, although the extra cache could be playing a role as well. Oddly, Seagate’s drive did under-perform notably in one test, Video Editing, but that was the lone exception. Overall, PCMark 7 deems Seagate’s ES.3 drive to be 7.4% faster than WD’s RE.
