Is 38MB/s with Esata correct?

[shevanel]

Just bought an external esata enclosure for a 32mb/500GB sataII hdd for my laptop to use as a media drive.. I am copying files over from the 500gb to my 7200rpm notebook drive via esata port and the speed is about 38MB/s

I was wondering if the transfer rate depends mostly on the destination drive?

How come the box of the enclosure advertises up to 3GB/S, this is why I am wondering if 38MB/s is acceptable?

Thanks for any info

Try running ATTO, HD Tune or HD Tach and share the results. eSata should be no different from regular Sata... It's the same thing.

Another problem I am having is the transfer is causing the PC to be laggy and unresponsive..

For instance, as it is tranferring and I am typing.. some of the text delays then pops up in a complete sentenace.. or a tabbed browser page delays for a couple seconds...

I'll run HDtune on the drive now. BRB

38MB/s from a notebook drive isn't too bad if it's a slightly older drive or damaged.
How long is your cable, sometimes longer cables can cause issues.

Its < 2 feet in length.

I ran error scan. All green in HDtune. Every so often though it would pause for a second and resume.. don't remember that.

For the 500GB "esata"
In the heath tab I get OK beside "Health Status"

Under benchmark I get

min: 49.5
max: 109.9
avg 87.8

12.4ms access time
burst rate 50MB/s
cpu usage -1.%

LOL, the laptop drive is laughable.. although there arent any errors showing up, the benchmark shows this

min: 1.1
max: 66.7
avg: 46.8

access time 15.5
burst 70.7
cpu usage -1

i will have an SSD in a day or so.. then I can use this 200gb drive just for music/movies.. i guess average was on par with the 40gb transfer @ 38-40 MB/s which took about 10-12 mins i think

so i guess you could say that besides a rather slow laptop drive that everything seems to be working as it should?

It all depends?
1. How fast does the notebook drive read?
2. How fast is the external drive at writes?
3. Are the drives defragged and optimized?
4. Do you have the cache enabled or is it set off and as quick swappable?
38 avg ain't bad though. Make that 87.8... nice.

My 500g wd green drive on esata does vvthisvv, running on a ASUS U236 PCIe x4 usb 3.0\SATA III (running at SATA II) card using HDTune.

You put the green drive to shame...


Edit: If you have drops and lags; it is probably some background tasks running or A\V or such. Run Taskmanager and see if something is using resources.

Forgot - 3GB/s is a theoretical limit for SATA II (pretty advertising point though), something I have yet seen obtained by a platter.

This is normal

 

[shevanel]

ok thanks alot. It's not often I have to move large amounts of files but I just wanted to see what was up with the 38MB/s and if it was average.. Now I have learned some new stuff day for my Bday lol. Thanks everyone

 

[95Viper]

Oh, then;

Let's us know how the SSD goes...

 

[niko084]

So we think 80mb/s is a normal throughput rate of a hard drive huh.

You guys are funny.
Do me a favor and copy data from one drive to another, do a 10gb file because 80mb/s is 4800mb per minute, NOT going to happen from a laptop drive, sorry. Use a stopwatch not a useless benchmark.

3 1/2 inch hdd..

intenal i/o chipset plug in

full speed of hdd..

say avg (hdtach) 80+mb/sec) new latest 2010 hdd, ie wd 500g green/blue black + seagate 7200.12/es2 hdd

notebooh hdd (latest models 2010) 55/60 mb/sec (5400 blue 640g wd hdd+ 320g 7200 rpm black scopio hdd 2.5"


via e-sata should be same ..

but transfering files from e-sata external hdd to internal notebook.. slows doen to (slowest hdd div by 1/2??? some times)

notebppk hets 60mb/se, avg to e-sata hdd prob 30-40mb/sec depending on / o/s + file sizes etc..


run hdtack v3.xx. try in on you internall hdd + e-sata hdd(must be plug in via e-sata) drivers must be fully working?

The fact the average on the drive you are copying to is 46mb/s is where your problem lies hence the 38mb/s you were getting, the notebook hdd is holding the transfer rate back, if they were identical drives you would be able to hit closer to the 87mb/s of the 500gb

 

[ISSA2000]

NdMk2o1o, spot on. i agree.. note book hdd= are 2 generation behind desktop hdd.

Ok, I moved the 200gb 7200rpm drive over to secondary bay and replaced with an OCZ vertex 60gb... I am about to see what the rate is when moving a file from the esata drive to the SSD compared to the previous results when I was using the stock 7200rpm hdd..

ill post results shortly

Ok I copied over 2 movies over to the ssd.. total size was about 8.5GB, transfer rate stayed at 106MB/s for a few seconds then ran consistently @ 90MB/s until the 2 movies were copied over and it took 68 seconds total to complete the transfer.

Also depends on what you were copying, 10,000 files at 1MB would take longer than 1 file at 10,000MB.

That's interesting.

I was copying over 49GB of music to the laptop hdd. It took around 12-14 minutes iirc

I just copied over 16gb of music to the ssd to see how long it would take.. 2 min 34 seconds
