hdparm results - performane

martinm 06 Dec 2007 21:26

hi there,

I am just started with a MyBook WorldEditionII (1,5 TB) and I am quit frustrated because of transfer speed. I tested on 100mbit and 1000mbit LAN, and I have to say that there is NO difference between. The box is so slow that I am really angry about WD.

I logged in via SSH and checked the share dev (md4). the hdparm performance tool gives the following:
__

[root@MyBookWorld /]# hdparm -t /dev/md4

/dev/md4:
Timing buffered disk reads: 46 MB in 3.13 seconds = 14.70 MB/sec
[root@MyBookWorld /]#

___

what the hell is that??? these WD harddrive should give a result of 70 MB/sec. so it´s quite clear that the network performance is also so bad.

Anyone around who can confirm this? is there any other system around giving a better performance?

thanks,
martin

Yes Martin, I confirm the same lame figures on all the MBWE and MBWEII models I've seen. Keep in mind that it is a cheap consumer grade NAS device; the MBWE are sold here in supermarkets, displayed between vacuum cleaners and TV sets. It's a poor design - hottest drives I've seen for years -, prone to failures, easy to brick … and funny to hack :-)

Looking for a performance comparison? Have a look on http://www.smallnetbuilder.com/component/option,com_nas/Itemid,190 … and you'll find WD products down down down the page.

Kind regards

The big question for is is, of course, how do we speed it up? :D

I'm interested in that as well.
I'm not asking for much, but at least it should be able to sustain a transfer rate of 50Mbit, not 35 as I have on mine and I fail to see any reason to why it performs so bad during transfers.

So, what can be done to its OS and possibly hardware through modification to speed it up?
