WD WD100EMAZ and WD Easystore 10TB External Backup Drive Review


Testing the WD Easystore 10TB USB Desktop Backup Drive

Here is our basic test configuration for the drive. We also wanted to test the WD100EFAX WD Red 10TB solution against this WD100EMAZ WD white label 10TB solution.

Motherboard: ASUS WS C621E SAGE Motherboard
CPU: 2x Intel Xeon Gold 6134 (8 core / 16 Threads)
Cooling: Noctua NH-U14S DX-3647 LGA3647
RAM: 12x MICRON 16GB Low Profile
SSD: Samsung PM961 1TB
OS: Windows 10 Pro

First, here is a quick CrystalDiskInfo 8 look at the WD100EFAX v. WD100EMAZ we are going to compare:

WD 10TB White CrystalDiskInfo
WD 10TB White CrystalDiskInfo

Both have the same Firmware versions and same rotational speeds. We wanted to see how closely they performed.


Next, we started running benchmarks and began with CrystalDiskMark, for a quick check on the disks.

Easystore WD 10TB White Label CrystalDiskMark

Both disks are relatively close in this test. Certainly within a testing margin.

ATTO Disk Benchmark

ATTO may not be the most popular benchmark for SSDs, but it shows sequential reads and writes which are the primary use case for hard drives.

WD 10TB White ATTO

With ATTO we also see both drives are relatively close in performance. There is a slight performance edge to the 10TB Red HDD, but the WD100EMAZ “white label” drive is relatively close in performance.


Parkdale is a fast benchmark which reports Sequential Read and Write performance numbers.

Parkdale shows the WD 10TB White drive to be approximately 10 MB/s slower than the 10TB Red NAS drives. We are starting to see a trend in our results.

PCMark 8 Storage Benchmark

PCMark 8 Storage Benchmark runs several applications and generates an overall score for the drive.

Here again, we see the WD 10TB Red WD100EMAZ is slightly slower than the WD100EFAX “WD Red” 10TB offering. The results are close, but there is a trend.

HD Tune Pro

HD Tune Pro can run several benchmarks on your drives; we unlocked the Pro version to give access to all benchmarks.

Easystore WD 10TB White Label HD Tune Pro Sequential Read
Easystore WD 10TB White Label HD Tune Pro Sequential Read
Easystore WD 10TB White Label HD Tune Pro Sequential Write
Easystore WD 10TB White Label HD Tune Pro Sequential Write

Again, we see a trend where the WD Red 10TB (WD100EFAX) is slightly faster than the Easystore derived white label WD WD100EMAZ.

AIDA64 Disk Test

AIDA64 has become a popular test suite, and so we wanted to run it with the drives. It shows the difference between reading and writing at different radius points on a hard drive which show drastically different performance.

First the read results:

AIDA64 Linear Write test is an extensive benchmark that takes a substantial amount of time to complete, with the 10TB drives this benchmark took almost two full days to run for each disk.

Data from this benchmark can be saved to an Excel file and plotted which we did for both the 10TB Red NAS and the 10TB White Label drives.

Easystore WD 10TB White Label AIDA64 Linear Write
Easystore WD 10TB White Label AIDA64 Linear Write

Both drives are relativity close and range about 8 MB/s difference in sequential write bandwidth.

There is a clear trend that the WD Easystore WD100EMAZ white label drive is slightly slower than a genuine WD Red WD100EFAX 10TB drive.

Next, we are going to discuss the drive temperatures along with giving our final words.

  1. I did this with the MyBook 8TB drives 2 years ago and put them in my OMV Nas. 6 months later one totally died. At that point I got a IronWolf drive as a replacement to have some differentiation. The other MyBook drive has been chugging along for the last 2,5 years though.

  2. I got 6 of the 8TB version about a year ago. Of the 3 that I’ve pulled so far, all are the WD80EFZX. One is being used as purchased and the other 2 are waiting to be opened probably, once I figure out my longer term NAS setup.

  3. My 2 cents – get a good power supply like a Seasonic Gold or Titanium if you’re having problems with drive failures. My combination of 40 plus various Seagates, WD, and Toshiba have never experienced a drive failure. Drives do fail of course, but clean power is important.

  4. I just got two of the 8TB yesterday they were both the EFZX, even between the two one was about 5-10MB/s faster when I did a 4 hour burn-in. Neither had any 3.3v issues in my system. One was straight to the MB the other was in a 3 disk hot-swap enclosure I got off of Amazon.

  5. I have a question, WHY can’t these drives be set up so that there is a DUEL storage system. Like you write to you D: Drive and it automatically copies the data that you just wrote to THIS 10Tdrive? –you have a double backup of your data? ONE on your principal drive and on the 10 T drive.
    With all of this space, you can then keep a separate BACKUP of data every month! BUT the duel back up happens immediately? everyday! every time you access your hard drive.

  6. AJ, if you want redundancy, I use a Drobo 5N2. 5 bays and you can set them up to be redundant against 1 HD failure or Dual HD failure. But note that dual redundancy really eats up drive space. I’m currently running 44 TB worth of drives (2-10s and 3-8s) and have 31 TB available with standard redundancy and 22 TB with dual redundancy. But since I have almost 1200 movies, over 80 complete tv series, over 6000 albums and some photography work on it, dual redundancy is just the thing for me. I would hate to loose that stuff.

  7. AJ, that is called RAID 1. A mirror of the drive, so the data is on 2 drives, if one drive fails, the other takes over.

    There is also software that will do this for you, such as DriverPool for Windows, or on Linux certain filesystems do this for you when you tell them to, such as BTRFS, ZFS and others.

  8. Excellent professional testing and an answer to the eternal question regarding these drives–what are they?

    We purchased 2 for use as is as just secondary backups as they were cheap and it seems they will do their job well.

  9. I have 4 of these (out of 24 drives) in a FreeNAS setup since a few months and 2 of them are already returning a 50-150 “Currently unreadable (pending) sectors”.

  10. I bought 4 of these not knowing they had come from am external kit- I installed them into my Synology 4 port NAS. In 4 months I have had to run Synology repair because of notices that a drive was failing. In fact the NAS. Is running a repair fight now (and it takes at least 36-40 hours. That didn’t for me.I bought a 10 Tb WD Red to replace the troublesome WD White, We will see what happens but I do not like these drives for NAS, Beware

  11. on the black sharpie or magic marker for labeling usb another tip is to cover the writing with tape afterwards as the ink tends to wear off over time

  12. You should correct wrong information in your otherwise great review. In the United States, shucking a drive does not invalidate warranty unless the process of shucking damaged the drive. This would have to be proven by WD. Therefore one could shuck the drive, use it internally, have it go bad then put it back into the enclosure and cigarette a right to claim warranty as long as they did not damage the enclosure or drive while shucking.

  13. VJ you have it right in theory and wrong in practice. It is up to WDC to warranty ANY drive, period. If you have a problem with them, you will find it much more expensive to fight with them about it than to buy another drive by another manufacturer.
