Very fast transfer speed (58.6 MB/s)


#9

To add on, I’m connected via LAN cable(Cat6e). I noticed the upload speed will be much more slower if I were to use WD My Cloud Apps to do the uploading. After some troubleshooting, I decided to give up on using WD inhouse app to do the file transfer.

Though I still cannot see your screenshot but as TonyPh12345 mentioned above, the reason you are probably getting such slow speed (as possibly many others are) is because you are likely using the wifi connection. In Windows 7, even if you have a wired ethernet cable plugged in, I realized over a year ago that for laptops (which almost all have wifi today) the default connection used is wifi - if for some reason wifi fails THEN does Windows 7 switch over to wired connection. And obviously a wired connection will give you much higher speeds - wired connection is the whole pupose most of us wanted to use a NAS in the first place. To use wifi to transfer files defeats the purpose of having a NAS hooked up to your network via a wired connection.

BTW, to check wthther or not your Windows is using wired connection when plugged in, go to Network and Sharing Center control panel and then from menu choose Advanced -> Advanced Settings (see pic below or this alternate pic is it’s not visible below ->  http://imgur.com/mcPuqy7 )

Then in Advanced Settings ensure that Local Area Connection is listed at the top of connections (like in pic below or in this alternate link -> http://imgur.com/tfoFjQF )- IF IT IS NOT then use the arrows on the right (circled in the pic) to move the Local Area Connection to the top of the list. ONLY THEN will your Windows computer be using the wired connection over wifi anytime the cable is plugged in.

In addition, you are using RAID 1. RAID 1, which performs simultaneous identical writes on both drives will especially hurt the speed of writing files. So combine RAID 1 write speed with a wif connection and you will get a pretty dismal speed, even on newer AC wifi routers than compared to wired connections with JBOD mode. There are always going to be tradeoffs - do you want to use wifi for convenience over wired for speed? Do you want to use RAID 1 for drive redundance (data protection from failures) versus JBOD for speed? Only you can make those decisions.

Thank you for replying. I would like to clarify that I’m using a wired connection speed not wireless as I have my wireless connection disabled at all times. I have done some research on raid configuration knowing that it does contribute to the speed of writing files and I’m quite satistied with the decent speeds now comparing to tortise slow speed when using wd apps :smiley: Cheers 


#12

By the way, i notice that the snapshot of my EX2 is always indicating the same without any changes in temperatures/fan speed even the physical HDD is burning HOT and the fan speed shows 0 rpm all the times. Is this normal? I have attached a screenshot for your reference. 


#13

Okay, so you have completely disabled your wifi then. Sorry, I didn’t see that in time so I editedmy last post adding some more info to make sure you are using the wifi connection. Well, it might be useful for somebody else perhaps in the future…so Ill leave that additional info and screenshots. But I think you should be getting much better speeds if you are indeed using wired connection, than what you are getting now…even if you are satisfied with the speed you are currently getting :slight_smile:

I think even when the drives get very hot after long sustained disk reads/writes, they are usually within the normal operating temperature range. I am not sure why your fan shows 0 RPM - but the best way to know ifthe fan is working or not is to bring your ear close to the back of the unit…you would feel slight warm air flowing out and would hear the very low noise of a fan blowing. Most of the time my fan doesn’t kick in but I have seen it sometimes kick in - although never really checked on what the dashboard diagnostics say.


#14

Ya, not until it bothers me again  ;D

Well, from what I have observered the fan never kick in even when the temperature is freaking hot that I can even fry an egg with it. I’m thinking of getting a cooling pad to place under it to deal with the heat.

Anws thank you very much for sharing the info.

Pull a diagnostics report fromt he Web UI.   There’s a file in the report with the name “smart” in it.

Paste the contents of that file (but redact the serial number.)

I’m curious just how hot your system is.

TonyPh12345,

I found out that you can run this test from dashboard’s Settings -> Utilities -> System Diagnostics -> System Test.

But I only got the result in a popup browser window and that too it was just a bunch of green checks. Based on your comment above it sounds like there is a report file generated somewhere. Can you please clarify where and what filename is it? I am curious and want to look at my stats too.


#17

Yes, and I just remember you can get SMART data directly from the UI on the EX4.  I think the Mirror has the same UI?

Go to main menu, select STORAGE, Disk Status, and click the SMART DATA link.

It will show the drive temperature.

To get the diagnostic report, log in to the UI, click the HELP (?) button at the top, select Support, and then select “Create and Save” system report.


#18

To get the smart data go to the storage menu item, click on disk status on the left then click where it says Smart Data.  I must tell you though that I dont believe what it says.  MIne says that the current temp of drive 1 is 107C (224.6F) and drive 2 is 106C.  The “Raw” value is 45 and the “Worst” is 99.  Since the curent value is higher than the worst and the drive is certainly not 200+ degrees according to my calibrated finger tip I have to assume that this data is highly suspect.

**EDIT**

One other thing, I have never seen my fan run on this unit and it is warm enough that I do think it should be running.  WD needs to address this issue.


#19

Hi Tony, as requested I have paste the details below. The current temperature is taken in idle mode.

Vertech: Which column are you reading?  The “Current” or the “Raw” value?   I think “Current” column is misnamed.  The column should just read “Value.”

sequalancer:  Your temperatures are normal; only 52C.


#21

Tony, I am reading the “current” column which says that it is 107.  The value for the “raw” column was 45 and the “Worst” was 99.   These are WD red drives that were preinstalled in the unit.  Should I be worried?


#22

I think the RAW column is the actual value. Mine reads 108 under current and 42 under RAW. My drives are not 108… That’s hotter than boiling and would severely burn skin. :slight_smile:

#24

Thanks WSGVET!! Wow, that IS superfast!! Will keep this in mind if and when I add a second disk…might just format both drives then and convert to RAID 0. I don’t care about loss of fault tolerance…don’t have that now either with my JBOD mode. I guess the speed gain over JBOD is balanced out by loss of a little bit of storage space, as I think in RAID 0, you don’t get all the available space of the two drives…you lose some of it…but that would be ok. I do have a question for you though - did you buy yours diskless? And if so, what drives did you put in? I’m curious to know if the speeds were impacted by you putting in some fast drives like WD Black drives, which wouldn’t be good for a NAS environment. But if you either put in WD Red drives…or just bought them pre-loaded with the default Red drives, then your speeds are all the more impressive. Please let me know this info. And thanks for your post. I am glad you and others have shared their positive speed experiences of the EX2 on this post. So now there is a slightly more balanced picture of the speeds, because I got tired of seeing folks grumbling about slow speed :slight_smile:


#25

I bought pre-loaded 2TB + 2TB product.

WD RED HARD.

And RAID0, RAID1, JBOD speed is almost same.

read : 90~100MB/s

write : 50~70MB/s


#26

Thanks, that helps in understanding your setup a bit more. My guess is that your ASUS RT-AC66R is making the real difference. I’ve been holding back on upgrading my router to an AC router, but I’ll have to put router on the planned replacements now. Since my highest speed N router from Netgear was already gigabit, I didn’t think I could get much improvement for wired connections by moving to an AC router, because I thought the only improvement would be on the wireless side. But now I realize that the benefit of a faster chipset does seem to make a difference even with wired connections. I already had the same ASUS router you have along with Netgear’s top AC router on my shortlist for many months. So when I do buy, it’ll come down to one of these two.

Interesting to know you have got comparable speeds between RAID0, RAID1 and JBOD. Thanks again for sharing these very helpful info.

Hi,

you have the same error that I have on my EX2…
