I got a wd 1TB eacs recently. Transferring data from my 1TB 7200.11 and an older 200gb 7200.7 ( or was it .8? maybe its .9) is quite slow, between 40-50MB/s :( I thought I would get at least 70mbps between the newer 1TBs. :ashamed:

Are these transfer rates ok?

P.S. Using teracopy for data transfer.
 
Hmmm could this be because of the slower 200GB drive? I dont use Teracopy/Burst Copy. Prefer the normal copy instead. :P

Here's a screenshot of the HD-Tune of my EACS 1TB:





I'm getting the following real-time transfer rates:

~78.5MB/s transferring a 1080p movie from a 640GB AAKS to the 1TB EACS.

~95MB/s transferring the same from the 1TB EACS to the 640GB AAKS.
 
i think its something to do with teracopy.

i use teracopy too and i get speeds like 35MBps on my 640AAKS, although these are transfers on the same drive but different partitions.

faheem also had a similar problem with his seagate hdd.

hdtune and hdtach show normal good speeds.
 
I'm guessing that you're getting slower transfers cause the older drive cannot write fast enough :huh:

@viralbug : transfers on the same drive will allways be slower as it has to read and write from/to the same drive

I guess none of us read b/w the lines lol. :P

Anyhow I hope there's no jumper issue on either of the drives. Are all the drives connected to the same SATA controller on the board?
 
Do new drives come with jumpers? :huh: Never bothered to check :P

Yeah and all drives are on the same controller.
 
40-50-60MB/s is normal speed. it's average transfer speed, while u transfer b/w.

Barracuda 7200.11 SATA 3Gb/s 1-TB Hard Drive

Delivers 1-TB capacity

Ships with the industry's most reliable and proven perpendicular magnetic recording technology

Delivers high performance

105 MB/s sustained data rate --> does n't mean it will always give 105MB/s. depending on the sector allocation on the file this will differ. Depending on the size of your File also. Depending on your Controller performance or Quality, also this will change.

Ya the word sustained means "continuous" , but depending on the situation and load this will change yaar.



32-MB cache buffer

Environmentally friendly

Idles at only 8.0 watts, enabling customers to build low-power systems

Meets strict RoHS environmental requirements

Leverages best combination of technology (areal density, PMR) and proven components for volume availability

EDITED for the Sake of layman's

=========================

The statement "Depending on your Controller performance" implies that SATA Controller(Chipset) you are using.

Some old NVidia Chipsets and ATI Chipsets and intel chips, the performance differs.

That's because of the technology and architecture implemented in the particular ChipSets.

That's all i can say from my knowledge and experience.

Rest is up to you guyz.. Thanks Guyz.

Can we have a screenshot of the HD-Tune supporting the claim please? Or a real-time bench.
 
Here are HDD tune test for WD640 AAKS.

I am getting over 100MB/S in copying from WD640 to 500GB Seagate.
 
It also depends on the size of the files that you are moving, i.e the smaller files usually take up a lot more time to copy that a single large file :)

Either back up your claims with benchmarks/ articles in the present context or stop acting like everybody's a fool here.

On topic, checked your controller settings and such? Maybe driver updates?

I'm sorry u guyz may be the kings. i accept that. i never said every body is a fool here. if u feels like that it's not my problem, or you didn't understand what i'm saying. :)

i'm just trying to help that fellow. in HDTAch and those thing it will show that data rate. but in real time while you copy a 4 or 10 GB files in between, how much transfer rate are you getting that's the point.

U copy some 10-20 GB data large files (chunk of 3,4 MB Each) and try that's all i can say.

The benchmarks on HDTach are based on small files like 100-300 MB, i will say copying 100MB - 300 MB files are very faster.

By the way i'm not retrieving my post. those who accept it and have faced it will under stand it.

:D

Bye the way one more thing. I didnt ever act like others are fools here. i shared what i know.

if u have any objection complaint to moderators.

if u r a moderator. if others are also feeling i'm wrong. delete my post.

:rofl: :cool2:

one more thing

Check that HD Tach Screen Shot above posted by @virus32win

Why the Data Transfer rate is reducing when it reaching up to 100%. It's depending on the sector right?..

Does it give full 120MB/s , not na. Average of 91. So think logically n act..
 
Nitin, dude, did I say anything about hdtach or hdtune? :P I said i get 40-50mb/s, people said they get 80-100mb/s (though with other hdds). Nobody here knows what you're talking about. :)
 
^^Exactly. 40~50 is way off. I'm getting an average of 60~70MBPs even from a Seagate SV35.2 750 which is one of the slower drivers considering it's mainly recommended for surveillance video recording.

@nithinmohantk, dude, we are all talking about real time transfer speeds.

Edit: Seagate Technology - SV35.2 SATA 750-GB Hard Drive

It has sustained rate of 78 Mbps (manufacturer specs). Now see the teracopy speeds connected thru a Vantec Nexstar e-SATA dock:
