Western Digital RE RAID Edition 4TB SATA Enterprise Drive - Full Review

Subject: Storage

Conclusion, Pricing, and Thoughts

Conclusion:

PROS:

  • Outstanding sequential read and write speeds.
  • File performance approaching 10,000 RPM VelociRaptor in some areas.
  • 5-Year warranty with 24/7 support hotline.
  • 1,200,000 hour MTBF (1,000,000 for WD Red Series).

CONS:

  • Not yet available in a 'GP' series (unknown if this will happen).
  • Different tuning might effect some workloads negatively (compared to prior gen RE4).

Pricing and Availability:

Volume shipment to standard e-tailers has not yet happened. As with all RE series drives, the added burn-in and initial bulk order volume makes it take a while to trickle down to the smaller folk. Here are the announced MSRP's:

  • WD4000FYYZ 4 TB, SATA 6 Gb/s $459.00
    WD3000FYYZ 3 TB, SATA 6 Gb/s $349.00
    WD2000FYYZ 2 TB, SATA 6 Gb/s $229.00
  • WD4001FYYG 4 TB, SAS 6 Gb/s $479.00
    WD3001FYYG 3 TB, SAS 6 Gb/s $369.00
    WD2001FYYG 2 TB, SAS 6 Gb/s $249.00
    WD1001FYYG 1 TB, SAS 6 Gb/s $139.00

These are clearly priced for the enterprise, as have all prior RE series units. My hope is that a more cost effective 'GP' variant will be launched. If that price sits somewhere between the Red and RE series, it might put these into the hands of some power users needing that extra 1TB per drive over the Reds (currently only available at a maximum of 3TB).

Warranty:

Standard Western Digital 5-year Warranty.

Final Thoughts:

After perhaps a longer than expected wait, Western Digital has released a 4TB hard disk in the form of its new RE series. RE drives have always carried a 'faster' track geometry than their consumer units, and this same case applies here. A heavier head pack resulted in slightly higher seek times, but our sample was able to keep random access performance in check and turn in some of the best file copy performance numbers we've seen from a spinning disk to date. Here's hoping we see the 4TB capacity point trickle down to the Red and Green lines soon!

It's RAID edition review without RAID benchmarks, right? Did I miss something or maybe you are not provided enough drives for RAID testing?

All of these drive tend to scale similarly when in a RAID, depending more on the RAID controller than the drive itself. WD had a very limited number of samples for the new RE.

To answer the first fellow's question. That is simply the name of the drive not what the review entails. RE is short for Raid Edition.

I have always wanted a SSD....Now i want 4 terabyte of hard drive space....

I am curious, do you think the 2TB and 3TB would perform the same as the 4TB version? Will the lower amount of platters and heads cost some performance to the lower capactiy drives?

What I also wonder about is the new line of specific SAS models. Aou can plug a SATA drive in a SAS controller without any problems, so why the specific SAS line?

Thanks!

You can plug a SAS device into a SATA controller but NOT a SATA device into a SAS controller.

You're backwards on that :). Most SAS RAID controllers can handle SATA.

In fact, it's exactly the other way around.
