WD Red 6TB Retested - Performance Restored

Subject: Storage
Manufacturer: Western Digital


I won't go into every single test as this is only an update piece. Instead I'll step you though tests which showed the greatest differences in performance.

While sequential performance is virtually identical between unpatched and patched Reds, Queue depth performance was an issue, so much so that differences can be seen in the access time reported by HDTune:

Next up is a look at File Creation times, where the updated Red showed a definite improvement:

Next up is PCMark, showing similar improvements:

Lastly, a look at Iometer:

As you can see from the above results, the updated (and currently shipping) version of the 5TB and 6TB WD Red have corrected the performance issues noted in our initial review. Since only a small portion of initially shipped drives were affected, Western Digital has chosen to provide the update to those users via their 24/7 support system.

I've just bought one of these drives and checked the WD support website. There's no mention of the firmware update.

Allyn, could you please post a link to the firmware update, or could someone point me in the right direction.

Check the link at the end of the story, I'm assuming that would be helpful to you.

Thanks, I got pretty much all the way to the end, but missed that last part.

I have to say I like the new chart style Allyn!

Thanks! Going for a cleaner look since some of our upcoming testing is going to present a lot more data.

Any idea if this firmware is applicable to the 5TB reds also? I understand it wasn't tested along with the 6TB and 4TB-Pro reds, but given they both had NASWare 3.0, I was hopping it would apply to the 5TB reds.

It should, and the model number convention should be similar as well.

I have a case open with WD for weeks and they are stalling to send the firmware. Last contact from them was 10 days ago. Don't know why they simple don't put the firmware on their website.

It took more than a month but I finally got the file.

Can someone please share the new firmware.

Wd support gets 1 million thumbs down by me, stalling communication for weeks with no end in sight.

Firmware update 68MYMN1 for WD60EFRX-68MYMN0
