There’s a relative lack of 4TB hard drive options on the market at the moment, but those looking for enthusiast or enterprise models are well taken care of. We’ve already taken a look at WD’s enthusiast part, the Black 4TB, so now it’s time to shift our attention to the feature-packed and enterprise-focused RE.

Synthetic: AIDA64 2.70

Similar to HD Tune, AIDA64’s built-in disk benchmarker is one of the easiest to run. The developer also keeps up on top of architectural trends so that you feel confident that the algorithms don’t get much better than this. This spreads beyond the storage benchmark, as AIDA64’s system stress-testers is one of the best, if not the best, out there – thanks to it being able to take full advantage of any given CPU architecture.

For our testing, we run the Linear Read and Random Write tests. Because AIDA64 by default automatically chooses a cluster size (which changes at random), we force it to use 64KB for our testing.

AIDA64 2.30

Our HD Tune test results showed that the RE 4TB’s write performance was about 13% faster than the Black 2TB, and AIDA64 helps make it definitive.

Overall, nothing can touch the VelociRaptor latency-wise, but as for the RE and Black drives go, we might as well call it even.

    Regarding the folder copy and folder transfer. What’s in them? Big chunk of files or small files?

      It’s all over the place. It’s meant to mimic a typical user’s “Documents” folder, so it includes a slight dab of music, lots of pictures and a ton of random documents. The largest file is about 300MB, the smallest is 1KB. Here’s a verbose look at the folder if you’re truly interested in the nitty gritty:

      windows has a rather high copy latency with 8.3 filenames… if you don’t need it disable legacy 8.3 support. I watched large directories that took days to transfer finish in under 4 minutes without legacy 8.3 support…

        I’ve never heard of this before. Will give things a test soon and see how our copy processes fare.

        Thanks!
