WD My Cloud: Performance Benchmarks


To check the performance of the WD My Cloud 2TB NAS we ran CrystalDiskMark 3.0.3 x64 with the default settings. This is a quick and easy storage drive benchmark utility that shows the peak sequential and random read/write speeds.  We paired the WD NAS with our test PC that included: Intel i7-4930K CPU,  16GB Corsair Vengeance RAM, NVIDIA GTX 770 all running on a Gigabyte X79-UD3 motherboard.


When we ran CrystalDiskMark using 1000MB packet sizes we saw speeds around 44 MB/s and 22 MB/s for Read and Write tests respectfully.  This is slightly slower than the speeds measured for the WD My Cloud EX4 that we evaluated a month or so ago.


We see from this next Crystal Disk Mark test, that the My Cloud NAS performance picks up when using smaller data.  Read performance jumps up to 56 MB/s while Write performance goes to 64 MB/s.  These performance numbers are something you might want to pay attention to especially if you regularly work with smaller file sizes.


Instead of just relying on synthetic benchmarks, we also used Teracopy and copied approximately 4 Gigs in a folder made up of raw pictures, and HD movies. When copying the pictures from our desktop via our Gigabyte LAN (powered by our Netgear R6300 Gigabyte router) to the My Cloud 2TB NAS.  Speeds measured when copying data from our desktop to the NAS were measured at 41 MB/s. The speeds we measured by doing a file transfer were consistent of those of the artificial benchmarks above.


We then copied these files from off of the WD My Cloud NAS back to the PC to get a real-world Write Speed for the My Cloud.  For this test, the copy time took 1:50 to copy exactly 4.09 GB of data – or 38 MB/s. 

These speeds aren’t going to set any records, but they are solid for users who are looking to expand their data storage options at an economical price.  Again when we compare these measured speeds to the WD My Cloud EX4 NAS, the $149 2TB NAS looks pretty good!

    I want to know that this device is supported usb 2.0 or not

  • Mahmoud

    how many users can collaborate and access one account simultaneously

    I’m curious to know if My Cloud works with PCs and Macs at the same time. What I mean is, at home I have an iPhone, iPac, MacBook, and a Windows 7 machine. Can all of these devices be connected to one My Cloud drive, or do the Mac and PC devices need separate My Cloud drives?

    • Nathan Kirsch

      Yes, all computing devices can connect to the My Cloud, including Mac and PC systems (browser and My Cloud desktop app). The mobile app is available on iOS, Android, Windows and Blackberry OS.

        Thank you for your response, Nathan.

    My 2T box is sitting here unplugged. No support, No instructions. Spent 3 days trying to get this thing to work. SLOW, SLOW, SLOOOOOOOOW! Support? There is NONE…

  • Brian

    how many users total? At any one time may log into the device?

    • Nathan Kirsch

      There is not a set limit. WD suggests 10 people at most, but mentioned to us that some users have told them that they have gone beyond that.

  • Carolyn Sasuga

    I have the 3T MyCloud and have problems viewing my files. I work in graphic design, therefore my folders have tons of pictures. Is there a way to change to View of my file from the little camera icon to Thumbnails?

  • Nyela

    Is this compatible with MacOS X’s Time Machine?

    • ivan

      yes it is

  • LinAdmin

    If you had a look in the support forum of WD MyCloud you would have found out that there are a lot of user complaints proving that the firmware of that device is unstable since the first shipments in Oct. 2013.

    I can not recommend to buy that product before a stable firmware is available!

    I have been reading a lot of reviews and description on My Cloud. Nowhere have I seen a word about file protection. Is there a block that will prevent 2 users from modifying the same file simultaneously? I would expect that the first user to opening a file that would set up a block such that any subsequent user could only open the same file as a “read only” file until the original user closed the file. Does My Cloud provide this level of file protection?

    • Binoy Raj

      Your OS will take care of this issue like you are editing a file in your local drive.

    • Nathan Kirsch

      With My Cloud (single bay) each folder has a user control on it that only a particular user has access to it at a time. However, if an Admin does enable multiple users to access the same file, and the users are both editing a file, there is a potential case that they could overwrite one another. This is normal under the fileshare structure (can occur on Sharepoint, Dropbox, etc.).

      For My Cloud Mirror, My Cloud EX2 and My Cloud EX4 there is a document flow management feature – a check-in, check-out feature. WD does support applications on those devices such as Joomla for content (CMS) and Git for version control.

    Thanks for your comments. The My Cloud device is password protected via it’s App. When you are remote, there is WD software that does the “handshaking” and you access it via a password login. There are a few pictures of the GUI in the article, but it’s a step more secure than your DropBox. Not exactly SSH, but it’s not like you can see it from a simple snoop.

  • Guest

    I would have like to have read more on Security of this device. If it’s going to be an online device that’s holding your files I need to know how secure is it?
    Otherwise nice writeup.

    Basically a VPN access though there is no VPN connection
