T530 - Insanely Slow SD card transfer rate

I'm curious if anyone knows why I might be experiencing insanely slow transfer rates from a particular 8GB Transcend SDHC 6 card? If I click on details while it is reading from the card, it will say 'Calculating...' forever. It will take like 5 minutes to transfer 3 - 1MB files. There are less than 200 pictures/videos on the card. The weird thing is that accessing the same card from my old laptop and my wife's laptop works perfectly fine.
And if I take my 16GB Micro SDHC card from my cell phone and put it into an SD card adapter and put that into the SD slot on my T530, no issues, it transfers files at normal speeds?! So it doesn't seem like the reader is bad, it just doesn't like that one card.
Any ideas?

Hi there dudeman,
Are all the card reader drivers up to date?
One of the drivers for the T530 listed here: http://support.lenovo.com/en_US/research/hints-or-tips/detail.page?DocID=HT073832 was recent, from August, under Camera and Card Reader. This may not solve your issue but I just wanted to suggest installing the latest drivers if you haven't already.

Super slow USB stick transfer rate. 2 Gigs in 2 hours ?

How can i speed up my USB memory stick transfer rate.
I'm using 2.4 GHz intel core i5 with 4GB 1333 MHz DDR3
Yet my 1 GHz windows laptop is much faster in copying files for the same memory stick.
How can i fix this?

You will not be able to use it on the Windows box if you change the formatting. But then you can buy another flash drive for Windows since they are cheap.
Drive Partition and Format
1. Boot from your OS X Installer Disc. After the installer loads select your language and click on the Continue button. When the menu bar appears select Disk Utility from the Utilities menu.
If you are preparing an external or a non-startup drive, then open Disk Utility in your Utilities folder.
2. After DU loads select your hard drive (this is the entry with the mfgr.'s ID and size) from the left side list. Note the SMART status of the drive in DU's status area. If it does not say "Verified" then the drive is failing or has failed and will need replacing. SMART info will not be reported on external drives. Otherwise, click on the Partition tab in the DU main window.
3. Under the Volume Scheme heading set the number of partitions from the drop down menu to one. Click on the Options button, set the partition scheme to GUID then click on the OK button. Set the format type to Mac OS Extended (Journaled.) Click on the Apply button and wait until the process has completed.
4. Select the volume you just created (this is the sub-entry under the drive entry) from the left side list. Click on the Erase tab in the DU main window.
5. Set the format type to Mac OS Extended (Journaled.) Click on the Security button, check the button for Zero Data and click on OK to return to the Erase window.
6. Click on the Erase button. The format process can take up to several hours depending upon the drive size.

Incredibly slow firewire transfer rate

Hi fellas
my firewire drive (formatted ext3) has an incredibly slow 2MB/s transfer rate?
Is this normal? Anything I can do about it?
Cippa Lippa

I have a FireWire 400 HD, it has a JMicron chipset (pretty generic but works great). I worked wonderfully on Leopard without a single glitch ever.
Now, after upgrading to SL, I experience the same as you and the drive is not responding well, hanging constantly and experiencing really slow transfer rates, that make it unusable (all applications that try to open something from it eventually hang). It's not a temporary glitch, even after several reboots and connecting/disconnecting the drive. The same drive under USB2 (it also has USB2 interface) works perfect (but I really want my firewire back).
I hope Apple fixes it! Definitely a bug.

How can I check the data transfer rate of my FW800 port

I have an iMac 2.4 20 inch (MB323LL/A) with a Lacie external rugged hard drive (320 GB). I have attached it using my FW800 port with the cable supplied with the drive.
It seems slow to me so I was wondering if there is any way to see what the current data transfer is for a backup in progress. Of course it should be 800Mbps but is it really moving at that speed ? How can I tell what speed it is transferring at ? Can I use the same method for USB ports too ?

When you move a large file, you are more likely to see a sustained transfer rate than a small file. Small files have to be individually read/write back and forth, thus slows the actual transfer rate down. If you are moving any file up to 4 GB and probably over 1 MB you'll see more realistic transfer rates. Furthermore your hard drive access time, and RPM figures into the equation too, as well as how much RAM you have. 800Mbps works out to 100 Megabytes per second under ideal conditions.

Slow Wireless and Erratic Transfer Rate

Alright, I just got a new Macbook Pro 15 inch last week because my iBook G4 kicked the bucket... again.
All has been well except for wireless. Any Wifi spot has had horrible transfer rates. The TX Rate goes up and down from 54/54 Mbits/sec to 0/54 MBits/sec over and over. This affects local transfer speeds (horribly slow), download speeds and even makes websites not load the first try.
It isn't the router being bad as I've confirmed the problem on more than one router and this is the only computer with the problem on all routers. An Intel iMac with the same (I think anyway) wireless-n card has no trouble at all either with the TX Rate to the same base station.
I tried booting into Windows (XP Professional SP2) but I can't seem to find any utilities to give me as detailed wifi information as AP Grapher does. It was hard to tell if there was a difference.
So is my wifi card at fault here, or OS X? This is a big issue for me and I can't seem to find any solutions online. Also giving a link to AP Grapher to show the TX Rate (the white line) going nuts.
http://socamx.net/tmp/apgrapher.png

i've got mbp with 10.4.11, that just started SLOWING down madly today..after all the research i see many have it much worse with complete loss of wifi...but this is HORRIBLE
i ran a speed test of IBM laptop side by side with MBP and downstream difference was 3X
HELP!

IPad2 - transfer rate USB to Win7 (direct acces) extremly slow

Hi Guys,
I´ve an iPad2 and like to download 50GB of raw pictures (used the Camera Connection Kit for this) to my Windows7 PC.
Connection via USB work, so I have direct access to my pictures but it´s incredible slow (1.6MB/s).
I´ve also tried it with another PC (also W7), same issue.
Any ideas?
Cheers

Hi Fred,
yes, 50GB is indeed a lot - but that´s the consequence of travelling around with a DSLR :-)
Nevertheless, it took not long to transfer them from my SD Card.
I´ve using of course a USB2.0 port, other devices like my portable HDD are running quite smooth.
I´ve read some tests done by photosgrafs and all of them are fine with the USB transfer rate.
Still no clue what´s wrong.
Cheers

E3200 slow transfer rate to synology NAS

Hello .
I just bought a synology NAS ds212j . I updated to DSM4.0. I purchased 2
Seagate ST2000DM001 Barracuda 7200RPM 2 TB SATA 6 GB/s NCQ 64 MB Cache 3.5-Inch Internal Bare Drive
My e3200 has the latest 1.0.04 firmware
I'm backing up via time machine(mac book pro) in MAC 10.7.4 which has a wireless N card.
in Utilities (activity monitor)I'm only getting 9 megabytes per second , why is it so slow? I feel like it's taking forever. e3200 says it does up to 300 megabytes per second. any possible settings causing this?
a backup of 202 gigs has been running for about 4 hours and still going
Solved!
Go to Solution.

The 300 megabits per a second claim is also dependent on the wireless interference around your area and the maximum link speed that the macbook pro's wireless chip can handle.
First, I would suggest visiting the wireless tab in the router's online interface and change the channel width to auto. That will allow the router to increase it's maximum speed to 300mbps if there isn't too much wireless interference.
After that, you can check the macbook's wireless link speed. Keep in mind that the usable speed (throughput) is usually around half of the link speed. That's just how 802.11abgn works.
I'm sure that if you tried a wired connection to the router, you would experience faster transfer rates compared to using a wireless connection.
I don't work for Cisco. I'm just here to help.

KT3 Ultra ARU Slow HD Transfer Rates

Hello,
First, please see my system information at the bottom of this message.
I have a MSI KT3 Ultra ARU motherboard and have installed a Maxtor ATA133 60GB hard drive with 2 MB cache. The hard drive is jumpered as Master and is connected all by itself on the IDE1 ribbon cable. On IDE2 I have a CDRW (Master) and a CD-ROM (Slave). My other hard drive (WD 120GB ATA100 8 MB cache) is on IDE3 and is set up in RAID 1+0 stripe.
I recently ran the Sandra file system benchmark on my hard drives with what I think are very discouraging results. My Maxtor drive on IDE1 scored 32 MB/s and my WD drive on IDE3 came in at 23 MB/s. Those are some stinky results aren’t they?
I checked my Device Manager under IDE ATA/ATAPI Controllers and it indicates that for my Primary IDE Channel the current transfer mode for device 0 is Ultra DMA Mode 6. I don’t know how to check the transfer mode on my IDE3 hard drive.
Question #1: Are my 32 MB/s and 23 MB/s results slow for my hardware?
Question #2: If these results are slow, how can I increase the transfer rates?
Please help!
Thank you!!!!
My System
AMD Athlon XP 3000+
MSI KT3 Ultra ARU MOBO
2 x 256MB DDR PC2700 SDRAM
ATI Radeon 9600XT 256MB

These tranfer rates seem fine for sequential read rates. The maxtor drive is at mode 6 and the WD should be at mode 5 if its ATA100.

Slow transfer rate to time capsule - 2nd generation - mb pro 5ghz

alright
have time capsule with dual networks, macbook pro with n enabled connected to 5ghz network with full bars, yet while copying files to the time capsule, it seems slow
500kbs per second
about 7 min to copy a 744mb file to time capsule (according to finder)
time capsule connected via ethernet to 2wire 2701hg modem + wireless router ( wireless turned off )
configure ipv4 using : dhcp
ethernet wan port: automatic
connection sharing : share a public ip adress
ipv6 : link local only
wireless options
country - mexico
multicast rate - high
transmit power - 100%
use wide channels
any ideas?
thanks in advance

Hi,
In the Manual Setup->Advanced->Logs and Statistics page of Airport Utility you'll find information on wireless signal quality for each client connected. Primarily, signal quality will determine the connection speed of your file transfers, the best you can do to improve things is to find a wireless channel with the least interference, Manual Setup->Wireless.
My Macbook Air connection is showing -66 Signal, -89 Noise, 122 Rate which gives me a wireless file transfer rate in bursts from 500kbps to 22Mbps. Time Capsule is not the fastest combo device, even file transfers over LAN Ethernet are around 50% slower than a regular Airport Extreme and I've found transfers to the disk from a GigE connected Mac Pro top out at around 60Mbps.
The Time Capsule is more useful as a convenience tool than speed I think so just be patient.

FTP/SFTP/FISH (etc) slow file transfer rate over LAN

Hi everyone,
I have a problem with transferring files over my home network that has been bothering me for quite some time.
I have a 802.11n router which should provide me with the transfer rate up to 150 Mbps (afaik). When I download files from the Internet, 3 MB/s data transfer rate is of no problem.
However, when receiving or sending data over LAN, the transfer rate is much slower (1.8 MB/s).
My rough guess is (after reading some papers on this topic) that TCP protocol is causing this (its flow control feature to be exact), since TCP max window size is too small on Linux by default.
So, setting TCP max window size to a greater number should solve this.
I tried putting this:
# increase TCP max buffer size setable using setsockopt()
# 16 MB with a few parallel streams is recommended for most 10G paths
# 32 MB might be needed for some very long end-to-end 10G or 40G paths
net.core.rmem_max = 16777216
net.core.wmem_max = 16777216
# increase Linux autotuning TCP buffer limits
# min, default, and max number of bytes to use
# (only change the 3rd value, and make it 16 MB or more)
net.ipv4.tcp_rmem = 4096 87380 16777216
net.ipv4.tcp_wmem = 4096 65536 16777216
# recommended to increase this for 10G NICS
net.core.netdev_max_backlog = 30000
# these should be the default, but just to be sure
net.ipv4.tcp_timestamps = 1
net.ipv4.tcp_sack = 1
in /etc/sysctl.conf but to no avail.
So either there is no problem with the max window size setting, or the Linux kernel ignores it (maybe because /proc is no longer supported?).
Thanks for any neat ideas.

Extremely slow transfer rate from iOmega eGo to iMac

I am using a brand new 27" iMac and an iOmega eGo 2TB hard drive (http://www.pcmag.com/article2/0,2817,2374133,00.asp). The drive has it's own power source and is connected to my computer via USB.
I'm trying to transfer files from the hard drive to my new iMac and the transfer rate is painfully slow. They are files from my old MacBook which I sold last week.
When the disc is not mounted, it seems to function normally - it's blue indicator light is consistently on and it sounds right. However, when I mount the disc and begin using it - in this instance to transfer files, it goes extremely slow. The blue light will mostly remain off, then interminnently flash on and onscreen a small amount of data will move.
Through disk utility I was able to successfully verify and repair the disc, but it's still behaving this way. Can anyone help? SOS!

Solaris 10 u5 Samba slow transfer rates?

Hi!
I've installed Solaris 10 x86 (Core2Duo - x64) server, with Samba over ZFS RAID-Z. Samba is a part of Active Directory Domain. I've managed to join it to domain, to get the users and groups from A.D. and to translate them to Unix IDs. Everything works really good. Samba is installed from the packages from Solaris 10 DVD.
Only problem I have is the performance :( It's disastrous!
On 100Mbit Realtek NIC, Samba can manage around 4 MB/s if log level is set to very high (10). If I lower it to 0, then transfer rates go up to 7.5-8.5MB/s and they fluctuate in that interval.
On the same network, there is a Debian Samba server, and transfer rates go high as 10.5-11.0MB/s.
Next test I did was switching to Gbit interface. That increased transfer rates up to 25 MB/s, but that is still 5 times slower than the theoretical limit.
So, next thing I've tried was to switch to Blastwave (CSW) Samba instead of SUNW Samba.... My transfer rates went back to normal immediately! It was a bit of shock for me... I could transfer about 10MB/s on 100Mbit interface, and around 45MB/s on 1Gbit interface. 45MB/s is theoretically limit of the workstation hard drive I was doing transfers from.
Sun packaged (SUNW) Samba is 3.0.28 patched today to the latest patchlevel, and CSW uses 3.0.23. I used CSW Samba with the exact same smb.conf file. Only problem is - I never managed to connect CSW samba to ADS on my network :( So I gave up on that, and I'm facing a dilemma. Managers request full speed of the Samba server (comparable to Linux/Windows shares), but I just can't connect to Domain with CSW package.
So I'm asking you guys - any ideas what could be the problem with SUNW Samba and performance? Is it just the 3.0.28 vs 3.0.23 issue, or what? Why is there so big difference in transfer rates? :(
Please help!

OK, here goes my smb.conf:

Time Capsule Ethernet Transfer rate very slow

Hello,
In order to transfer a 65Gb file from an iMac to TC, I decided to use the Ethernet port instead of wireless. The transfer rate is about 1-2Mbs /s instead of a regular Ethernet 100Mbs /s. It's been 4 hours so far and will probably be 7 hours when it's completed.
Facts
I turned off Airport.
I'm using an Ethernet CAT5 cable.
Why is it so slow?? Is there a setting I'm missing?
Thanks,

In the real world if you have ethernet 10/100/1000 and are using a cat 6 cable then expect no more than 11M/sec
8 M/sec if wireless N
4 M/sec if wireless B/G
Cat5 you'd use for ethernet 10/100 narrow band width.

WRT54Gx2 with GX400 wireless card, what type of wireless transfer rates you guys getting?

is this normal or really slow?
with the router in the same room or 3 rooms away with full signal.
i am tranfering a 100MB file, it usually takes me around 60 seconds to transfer it each way. thats around 15Mbps correct?
if so why is it so slow when 1 its should transfer around 54Mb and the laptop wireless status saying its connected at 108Mbps.
how do i speed this thing up or do i have a bad unit?

Hi , when you are connected to a 100Mbps network, you do not in effect get pure 100Mbps transfer rates.....the like will give you more of an idea .... http://kb.iu.edu/data/aeud.html

Hanging iMac, slow transfer rates

Hello,
I'm experiencing two problems with my iMac which I think are probably linked as they began around the same time. I've scoured these forums and several other websites for answers but I haven't found many people whose problems sound exactly like mine.
My iMac was running Tiger up until around a year and a half ago. I then upgraded to Leopard without any issues, and everything ran smoothly. About a year ago I began to experience some strange behaviour - Flash would repeatedly crash, my mouse seemed unresponsive, and the system began to hang as though it was having trouble processing things. I reinstalled Leopard and things seemed ok, though the hanging remained (at this stage it was just the umbrella spinning and things taking longer to load). I upgraded to Snow Leopard hoping this would fix the issue when it came out and things got incredibly bad. Starting up and loading to the desktop took upwards of twenty minutes!! Doing ANYTHING seemed to be a massive strain on the system. I'd literally have to spend an hour or so monitoring it just to check my email and shut down in the correct way. Additionally the USB transfer speed, and download speed, had dropped to the point where a 20mb file had an estimated time of 2 hours to or transfer from my external hard drive. Internet downloads were similar.
After as many tests as I could manage I thought it might be RAM related, and upgraded to 3gig. It had no noticeable effect. Recently, whilst trying to solve the problem, I gritted my teeth and backed everything up. I wiped the system entirely, and tried a clean install of Leopard (the last functioning OS I had). It worked, in so far as the catastrophically slow behaviour stopped, but I'm STILL left with the slow transfer speeds, and the hanging. I've since re-upgraded to Snow Leopard, and this time it functions in the exact same way as Leopard.
To describe the problem in detail: Every few seconds - the time between varies from 2s - a minute - the system stops responding for a seemingly arbitrary amount of time. Often the umbrella appears. However, when it appears frozen the dock usually responds without any issues (though is entirely impotent as I can't open anything, including Finder) and if I'm typing then when it returns to my control anything I typed will usually appear. My USB transfer rates remain, even when there's no issue, extremely low. Same with downloads. The most bizarre thing for me is that during the times the system is responding (during which is can often manage multiple tasks without any complaint) it moves and respons in an incredibly speedy, efficient way - as though the RAM upgrade has really helped.
I've tried repairing disk permissions, checking activity monitor to see what may be a strain on the system (everything looks entirely normal), I've run several diagnostics (including tests on the new RAM and the old RAM and on the external hard drives), defragged, turned out absolutely EVERYTHING unnecessary... Nothing I do seems to have any effect on this behaviour! Does anyone have ANY ideas? It's going to be a real pain to get it to an Apple store.
Edit: The reinstallation of an OS, or wiping of the hard drive took between 18 and 24 hours a time, despite it usually showing a countdown from 30 minutes the whole time.
