Hardware :: PATA Socket Was Replaced With SATA Socket / Transfer Rate Of The Harddisk Would Be SATA Transfer Rate?
Jul 4, 2010My friend bought an old hard drive. He noticed something with the hard drive that it was just replaced with a SATA socket. So meaning, the SATA socket was soldered to the PATA hard disk to replace the PATA socket to SATA socket to make it a SATA.
Now the question is:
1. Does the Transfer Rate of the harddisk (that has been replaced from PATA socket to SATA socket) would be SATA transfer rate? OR would still be PATA transfer rate?
Networking :: NAS Over WiFi Transfer Rate
Mar 27, 2010I have a LaCie NAS which is mounted on my main linux machine over a wifi LAN using the cifs file system. I would stupidly expect the transfer rate between my hard drive and the NAS to be limited by the Wifi speed (54 Mbps) but when I transfer files, the speed tops at 1.9 Mb/s which is roughly 15.2 Mbps. The most puzzling thing is that when I do multiple simultaneous transfers, I reach approximately 3MB/s in total but none of the individual transfers goes beyond 1.8. Does anyone have an idea about what is keeping the transfer rate so low?

View 1 Replies View RelatedNetworking :: Transfer Rate For Gigabit Ethernet
Apr 1, 2010We have a Linux box which acts a a file server. Currently, files and directories are exported using NFS.At the moment, we are a bit concern on its data transfer performance. FYI, we are using a embedded Gigabit Ethernet port on the file server. We ran a few simple write tests between NFS client (also utilizes GigE port) and the NFS server. In these tests, both NFS server and client are both connected directly to each other with a Cat5E cable. Unfortunately, the write/transfer speed results are not as per our expectation. It scores roughly about 11-12MByte/s, where as theoretically Gigabit Ethernet transfer rate is able to reach up to approximately 120MByte/s.I wouldn't expect to reach the theoretical max transfer rate (it would be great if we can , but I would appreciate if you guys can share with us in terms of the following :
1) What's the practical max data transfer rate which you guys managed to observe in a normal Gigabit based connection? What about jumbo frames configuration?
2) Is there any additional tuning/configuration we need to do within the OS to reach those practical max data transfer rate figure?
3) Does PCI-e / system bus plays a role in achieving this speed? For example, we are using the embedded GigE port and we heard some people says embedded ports are actually sharing the system bus and resources with other devices, which might adds into performance issue. Correct me if I'm wrong.
4) Does converting to Cat6 cabling will guarantee an increase in the data transfer performance?
5) In the future (once we are clear on how much single GigE transfer rate we can go) , we are looking into doing bonding since that the NFS server's shared directory/volume read-write speed is way much higher (i.e 400-600MByte/s). Will bonding allow us to achieve higher NFS read/write speed? What are the bonding modes best used for this purposes? Appreciate if anybody who has experience in doing bonding for NFS can share their experience.
Fedora Networking :: Slower Data Transfer Rate In KDE V GDM?
Nov 25, 2010I have a FC13 box that has both Gnome and KDE sessions installed.
I have noticed on the KDE session that data transfer rates are slower than when I use Gnome.
In Gnome, I can transfer files between my FC13 machine and my Ubuntu 10.04 pc at a rate of 6.5 MB/s (52 Mb/s if my maths is correct), but in KDE the rate is only 3.5 MB/s (28 Mb/s).
"ethtool eth0" shows my NIC speed as 100 Mb/s. Obviously I am not hitting anywhere near that speed in either session, (a separate article may be happen in the future to address that), but I am curious as to why KDE is that much slower for file transfer.

Fedora Hardware :: Low Transfer Rate When Copying Large Files Over Wireless
Jan 11, 2010I just bought a HP 3085dx laptop with an intel 5100 agn wireless card.
The problem: copying a big file over the wireless to a gigabit hardwired to the router computer only gives an average 3.5MB/Second transfer rate. If I do the same copy from my wireless-n macbook pro to the same computer. I get a transfer rate of about 11MB/sec. Why the big difference? I noticed the HP always connects to the 2.4 GHZ band instead of the 5GHZ bands...

Hardware :: Unbelievably Slow Transfer Rate To IRiver Media Player
Apr 7, 2010I recently purchased an iRiver P7 media player which I am using with Rhythmbox under Ubuntu 9.04. The transfer speed when uploading files to the player is phenomenally slow - the first 50 or so MB reported virtually instantly then the speed immediately drops to about 12-15KB/sec yes KB/sec so a 3-400MB video file takes hours to transfer to the player. This happens with the internal memory and the added memory (SD card) too, althoufg it is faster ror the SD card. No other devices have ever behaved like this on this system (and I have used 2 different Creative players, a different iRiver player and numerous memory sticks). The computer is dual booting with windows (for once that was useful) and under windows it doesn't happen, the speed is as expected so it isn't the hardware. I don't want to have to resort to damned windoze just for this. dmesg after plugging in the player shows it identifying both the internal storage and the added SD card but I don't understand the rest of it:
[code]....
This last message gets repeated lots of times, and during transfers it seems to be issued continuously and I suppose this is why the system is so slow because it is always retrying loads of times before a success.
Ubuntu :: Internet Conection - Transfer Rate - When Active - Is About 149b/s Receiving - And About 70b/s Sending

No Internet-related program was running from my part...In an attempt to pinpoint what was causing this, I occidentally removed the tools located left and right on the time and date. I've rebooted since but still no tools. The 0/I button is also gone.

- added a modeline to xorg.conf
- reinstalled nvidia driver
- tried the screen on a windows desktop, this worked so the monitor is fine

The modeline I tried, tried it both in screen section as well as in a seperate "Modes" section:

After restarting X the screen only does 1024x768 max because of the modeline

Ubuntu :: Laptop Refresh Rate Stuck At 50hz With Intel 965gm Graphic Card?
Feb 28, 2011I had an old thinkpad x61s laptop running ubuntu 10.10 with an intel gm965 graphics card. When i checked the monitor today it says the refreshing rate is 50hz and there is no other option available. I vaguely remember it used to be working at 60hz when I was running xp, so I googled and searched the forum for answers but came with no luck. Some people reported a similar problem with their nvidia graphic card and they seems to be able to modify a xorg.conf file to manually solve the issue (sadly I don't know how).
View 4 Replies View RelatedHardware :: Transfer Speed To SDHD Card
Mar 19, 2010I connected a 16GB SDHD Class 4 card to my PC with a dongle reader. A class 4 card is supposed to support a minimum of 4 MB/s sustained speed. I grabbed a couple of large, 4.4 GB each, files and copied them to the SD card with Nautilus. The transfer rate started out at 60 MB/s and rapidly dropped to 50 then 40 and slowly dropped to 3.5 MB/s after about 3 GB transferred and it is still dropping.The PC will copy from drive to drive at 65 MB/s so I do not think the issue is reading from the hard drive.I am confused about the transfer speeds which Nautilus is showing. Obviously I am not really transferring to this card at 50+ MB/s. If I was moving data from hard drive to cache I would expect much more speed - I have 8 GB of RAM on the PC. That said, I have stopped the transfer and attempted to unmount the card. I get the message "Failed to eject media; one or more volumes on the media are busy." This has been going on for several minutes so some activity is going on in the background.

View 6 Replies View RelatedDebian Hardware :: Damaged MicroSD Card During File Transfer
Oct 13, 2015I pulled the MicroSD card out of a non-working Android phone to backup its data onto my Debian system. My Desktop is Cinnamon and I was simply using copy/past from within Nemo. The files began to be transferred but during the transaction a dialog popped up declaring an input/output error. From that point on the card was not readable on my system.
I initially plugged the card into the computer via a USB card reader. I later tried using an SD card adapter and plugging it in my printer's SD slot. Still the system would not recognize the card. I also tried plugging the card into another Android phone. The phone could not read the card and attaching the phone to a computer did not recognize the card either. I then logged into a Windows 7 system but it could not detect it. The partition manager always showed the USB drive or SD slot as "device not connected". The last thing I tried was putting the card, with the SD adapter, in my camcorder. The camcorder prompted to format but failed to do so.
I would like to recover the pictures and videos off of the card but I am afraid that there may have been hardware failure on the card's controller. I have been searching around most of the day trying to find a solution but nothing I have tried has rendered it detectable on any system. If it is controller failure, need repairing or recovering data from physically damaged SD cards?
General :: Sony PSP File Transfer Inaccurate Transfer Progress?
Jan 1, 2010Having a bit of a issue with Debian Squeeze and transferring files to the Sony PSP..Hook up PSP to USB port and Debian mounts it..I go to drag a 125 meg mp4 to video folder..Copy windows takes about 10 seconds to transfer it..Exit USB mode and there is no video there. Go back into USB mode and look at video folder on the PSP memory stick and there is no video..It vanished. From another after copy progress closed I right clicked PSP and unmounted it..
It error-ed saying device was busy and could not unmount..Looking at light on PSP i see memory stick is still being written to..i wait for light to stop flashing..About a minute or so..Then am able to unmount it..Go to PSP video and theres the video ready to be watched. Debian isnt accurately showing the copy progress...Its showing complete when it isnt..I have to watch the light on PSP to know when it is truly finished.

This aint related to window manager, as same is case for KDE and XFCE tried thunar, konqueror, midnight commander, all of em resulted with same problem.
