How fast are the drives in the My Cloud products, i.e. 5400rpm or 7200 rpm?
Thanks,
MADMELVIN
Thereâs no guarantee of either. WD puts whatever drives in there they choose. Could be a WD red, black, or even Hitachi GST.
What? It is not 100% WD Red? O.o **bleep**?
How can I check it through SSH?

I think Iâm going to play it safe and purchase an NAS drive enclosure and put a FAST, 3.5", 7200rpm, 3TB bare drive in it. That way I know what Iâm getting when I install it in my office.Â
WD shouldnât go out of their way to HIDE the drive speed on their âMy Cloudâ products. The relatively uninformed shopper is not going to know how to accurately compare products â especially if WD manufactures the My Cloud producd with a variety of different drives (and brands?). The techies (such as myself) have to spend valuable time clawing through manufacturer websites and forums to get the answers â and even THEN itâs next to impossible to get the drive speeds unless someone on a forum happens to tell you.
Iâve purchased several out-of-the-box WD and Seagate enclosed drives (similar to the My Cloud and My Drive) and most crashed and burned within a year. Inferior drives? Could be.
Thanks for the feedback, guys! Youâve made my decision a LOT easier!
Have a great day!

Iâm just curious, but what possible difference does it make what the driveâs rotational speed is as long as the drive performs according to its published specs?
I doubt they would put in a non-WD harddrive into their NAS, itâs probably much cheaper for them to use an in-house product than to buy a third party harddrive.
For an office I wouldnât recommend the My Cloud because itâs a single hard-drive solution with no RAID (i.e when the hard disk crashes, you got a problem).
I use the MyCloud mainly for entertainment and backing up non-crucial data. For that purpose the My Cloud is a perfect match.
Also the hard drive is most often not the limiting speed factor⊠Processor/RAM/Network Stack and Bandwidth are most often the bottleneck 
Here are the spec sheets for the drives: http://www.wdc.com/wdproducts/library/SpecSheet/ENG/2879-771442.pdf

it can be like this for WD external products other than My Cloud family. For My Cloud devices shiped from WD with drives only WD RED drives are used (even for single bay product)

Thatâs good to know!
Thanks, Serhio.
My 2 TB My Cloud is using a RED drive as well. Iâm relieved to hear that My Clouds are shipping with actual NAS drives because I heard someone had a cheap green or blue drive in their My Book Live.
This is the drive they used for my âMy Cloudâ itâs model WDC WD20EFRX
http://www.wdc.com/global/products/specs/?driveID=1086&language=1
Thanks WD. Iâve used WD black drives for a long time in my desktops, but this is my first home âcloudâ NAS attempt and so far WD has made it pretty easy. I hope reliability of the unit itself is solid as well.
As a side note to WD. Now that you stated that you are using WD RED drives in the My Cloud line, It would be great if you could be less secretive about it. I saw no mention of the type or model of drive it used when looking at the actual product page. Just saying⊠Thanks.
I take it I need to use SSH to run this command?
hdparm -I /dev/sda
LinAdmin, hereâs a guide I wrote to look for network issues.  Not sure if youâve looked at PHY or TCP errorsâŠ
Itâs PC specific, not Mac, but the concepts would be the sameâŠ
hdparm -t --verbose /dev/sda
/dev/sda:
Timing buffered disk reads: 40 MB in 3.07 seconds = 13.01 MB/sec
hdparm -tT --verbose /dev/sda
/dev/sda:
Timing cached reads: 214 MB in 2.01 seconds = 106.30 MB/sec
Timing buffered disk reads: 46 MB in 3.11 seconds = 14.80 MB/sec
This should be faster, shouldnât it?
Can somebody post his hdparm output using a wd cloud red drive?

drive was idle, should I be worried?

Well, ok, then â maybe yâall are on to something.
If that pans out, then kudos.
I canât for the life of me imagine what could cause such a large discrepency on the mainboard.
DoÂ
/cat/proc/cpuinfo
The bogomips rating is calculated by executing a loop of code when the init is the only process running - even before If thereâs a hardware difference, it may be reflected there.
Whatâs your BogoMIPS rating?
What does this say?:
cat /sys/devices/system/cpu/cpu*/cpufreq/scaling_max_freq
Mine all say 650000000
