Data transfer rate requirements for iMovie?

Hi,
I was considering picking up a mobile external hard drive. One that I'm interested in is
http://www.lacie.com/products/product.htm?pid=10691
I was wondering if the transfer speeds would be adequate for use with iMovie projects?
Could anyone recommend this or any other mobile HD for around that price!
Thanks
Powerbook G4, 15", 1.67ghz Mac OS X (10.4.7)

Well, the first one was USB2. I agree with Leo that I'd prefer to stick with Firewire, but USB2 would probably be adequate. (USB1 would be completely unacceptable for this. )
(Oh, and raw DV is 3.6MB per second -- just to get more specific. Any modern Mac should have no trouble doing this. My dual-867 could handle it easily from the factory, and now I have much bigger and faster drives anyway. In the old days, grabbing analog video at 320x240 meant around 5MB/sec, and my old Power Mac 9500 with a SCSI2 drive could almost sustain that.)
Do you have a tower case with a spare hard drive bay? If so, unless you really need the portability, you could just slap another hard drive in the case.
And LaCie has a good reputation, but wow, those are expensive. You could put together a 120GB drive and an external case for just under $100. Or for $250-270 (still cheaper than the second one, and not much more than the first), you could put a 500GB drive in an external case. (And the external cases I'm talking about have both Firewire 400 and USB2.)

How to find the max data transfer rate(disk speed) supported by mobo?

I plan on replacing my current HDD with a new and bigger HDD.
For this I need to know the max data transfer rate(disk speed) that my mobo will support. However, dmidecode is not telling me that. Am I missing something?
Here's dmidecode:

I just checked my BIOS and my current setting is set at IDE although it also mentions that the default should be AHCI. Currently I have a dual boot of Windows 7 (need it for Tax software) and Arch
So I guess, when I get the new HDD, I will first set it to AHCI and then install the OSes on it. See if NCQ helps any, and if not I will turn it back and re-install (if I have to). I am planning to have Windows only in virtualbox in the new drive.
Anyhoo, while I was in the BIOS I found two things which I had questions about :
1) Under Onboard Devices --> Integrated NIC , my setting is currently set at "On w/PXE" and it says the default should be just "On". Would it be ok to change it back to On since its a single machine and its not booting an OS on any server. I just don't want to have to re-install anything now since I will be doing that in the new HDD.
2) How would I know whether my BIOS would support a 64 bit OS in Virtualbox? I checked some setting under Virtualization, but they weren't very clear.
I will edit this post and let you know exactly what settings were present under the Virtualization sub-section.

Determining Data transfer rate through modem in java

Hi,
I want to write an application in java which will communicate with
connected modem of the system and it will detect the data transfer rate.
I want to know how much data is transferring(upload/download)through modem and in a specific time how much data is transferred.
I will give some max upload/downloading limit for a specific time and if data transfer exceeds that limit,it will show message.
e.g if i fix max upload/download data transfer limit by the modem is say 10GB/20GB for a specific time span say for 15 days.Then my program automatically will start when the Modem will be connected and keep a log of data transfer(upload/download)and if data transfer goes beyond limit then it will show message.Also i would be able to see how much data is transferred for any specific day.
I want to know this type of application is possible in java.If yes then
which API's i need to use.
If this type of program is available in some site in other language then also i will be helpful.Pl give the links.

Hi,
i want to do it in java only to explore the power of
java.I agree with Abuse, Java is not designed for such applications. I'm not even sure if you can solve your problems with Java.

Transfer of Requirements for Return Orders

Hi,
Please I need help on TOR management with Return Orders in SD.
I've already red all the threads realted to TOR and ATP but I couldn't find a solution. As we know TOR is dependent on the following data: reqts type, reqts class, checking group and schedule line category.
The reqts type and class are determined in the strategy group (material master - MRP3).
Now if I switch on Transfer of Requirements for Returns, at Schedule Line level and Reqts Class level, the result is that I can see requirements related to Returns in the availability check overview of Sales Orders (ATP count) but if I check in the requirements list (i.e. transaction MD04) these requirements related to Returns are not recorded. Why?
And also another point please: requirements generated from Return Orders, into ATP count are considered as normal Sales Orders (negative sign, reducing ATP quantity, when it should be the contrary because a goods receipt is expected).
Can you help me please on these 2 points (perhaps something related with Sales Document Category)?
Thank you very much
Kind Regards
AP

I practically did a sample order / returns order to see your requirements and these are my observations
a)
If you create a standard sales order, then the availability check registers a minus sign with stock required in Rec./reqd qty field.
Once you save the sales order, this is not seen again as the total quantity is reduced by sales order quantity.
It was indicating a minus sign when you created a returns order because you checked the Transfer of requirements and availability check indicators in schedule line category.
It was simulating a requirement as you checked the indicators in schedule line category.
If you create returns order with standard DN (i.e. Transfer of requirements and availability check indicators are not checked), then you would not see any requirement for stock i.e. you don't see any new entry in availability overview screen.
b)
You are not seeing returned quantities in MD04 because of Movement types. This has nothing to do with Transfer of requirements.
Schedule line DN uses movement type 651.
Using movement type 651, you post returns from a customer with returns delivery to blocked stock returns.
The blocked stock returns are are neither valuated nor part of "unrestricted-use" stock.
Hence you are not seeing the returned stock in your available stock.
If you click the magnifying glass on total stock i.e. top line of your stock/requirements list (transaction MD04), you could see the returned quantity in 'Returns field'.
If you want to post returns from a customer with returns delivery directly to the valuated stock, you could use the following movement types in schedule line category.
653 Returns from customer to unrestricted-use stock
655 Returns from customer to stock in quality inspection
With these movement types, you could see returned quantities in stock/requirements list.

Difference in data transfer rates between winXP and Linux server?

Hello all,
I am using a winXP laptop to act as my server (all usb external hard drives are connected to it) but the data transfer rates can be really slow. Is Linux faster in that regard? Can a Linux based server provide faster data transfer rates?
Thanks for any help.
Bmora96

Linux cannot make hardware go any faster - so if WinXP and its drivers are making optimal use of those USB drives and the USB data transfer pipe, Linux will not make it faster. (but installing Linux and going Tux are always excellent ideas that need no real reason either ;-) )
Real question you should be asking is if using a notebook in a server role is wise thing to do?

Disk data transfer rate - iMac 2013

Good morning Apple fellows
First of all, sorry for my troubled English speaking, I'll do my best to explain the issue I'm having in the best way possible.
Yesterday I finally received my new iMac (I'm a proud Apple user since 2006), the machine has these specifications: 16 GB Ram, i7 processor, nVidia GT 780M, and a SSD drive of 1TB of capacity.
Under Mavericks everything runs smooth and fine, no issues at all, just perfect, the fastest machine I've ever had. Unfortunately, I had to install Windows 7 via Bootcamp (I'm a mechanical engineer and I use Autodesk Inventor to do my stuff).
After completing the installation of the Microsoft OS, I instantly noticed some laggy performance while running Windows: I installed as asked all the Bootcamp drivers with the USB pendrive that I prepared, but both the startup of the system and the normal use were a bit slow, even slower than my old '09 iMac.
In order to understand what the problem was, I ran the system performance test included in Windows: all the ratings I have are maxed out at 7.9 (7.9 is the top I think), in exception of the "Disk Data Transfer Rate", that is 5.9. As far as I remember, this value is typical for a mechanical disk drive, not for an SSD drive supported with PCIe connections.
Does anybody here got a similar issue? Is there any driver package that I have to install in addition to the Bootcamp drivers?
Thanks in advance

That is because the WEI uses your boot disk as the default device to measure performance, and, for instance, a Velociraptor 10 K disk, does not score more than 5.9. The story changes when the test is run on other disks, like my array:
However, this measurement is totally worthless in real life. You should look at practical benchmarks like PPBM5 Benchmark

Limit Hyper-V Replication Data Transfer Rate

Hello,
i need to limit data transfer rate for Hyper-v replication because between two Datacenter have bandwidth limitation.
Please suggest

You can use the New-NetQoSPolicy cmdlet to set the throttling limits -
http://technet.microsoft.com/en-us/library/hh967468.aspx. Based on the destination port (the port on which the replica server has been configured to receive replication traffic - maybe it's port 80 in your case) or the destination subnet, you can specify
a throttling value (-ThrottleRateActionBitsPerSecond) or assign a weight (MinBandwidthWeightAction).
Eg: New-NetQosPolicy "Replica traffic to 8080" –DestinationPort 8080 –ThrottleRateActionBitsPerSecond 100000
or check the link to Thomas blog

K9N SLI PLATINUM low data transfer rate

Hi, (sorry for my pour english) I had to go back to Winxp native SATA/IDE drivers and my pc crash & BSOD problem it's gone! :D (BSOD when i install some programs or some games, listening music and moving data at the same time, etc.) now i'm available to execute multitasks without any troubles. But now the transference it's quite poor , I think this is an easy and temporary solution for this big problem.
I bought my PC on 2006 and the Windows XP drivers are from 2001, aren't new Nvidia/MSI drivers to fix this annoying problem?
Thanks.

I've got nearly the same problem, but a little worse. My data transfer rate seems very slow for a 100mb network and if I start copying files over the network, after only a couple of megs I lose connectivity to the network completely! I've removed the network cable and windows notices this, and when I put it back in windows also notices the change, but the green and orange lights on the port itself stay on solid. If I reboot windows everything comes back. I don't have problems browsing the web, seems to only happen when the ethernat port is running close to full load (for the connection speed of 100mb as apposed to 1gb).
Anyone else seen this? I'm on the latest drivers, the latest bios and I've tried disabling on of the network ports in the bios but his didn't work.

Data transfer rate Airport Extreme

which is the data transfer rate of the USB port in the Airport Extreme (4ta. Generation)...???
The HDD installed in that port, reads and writes very slow

I executed the test and I have a rate of data transfer of 1.9 escrtura of Mb/s and 2.7 reading Mb/s…. this is very under… What I can do.?
I even reinitiated the Airport and itself with the problem. I directly tested with the ports of iMac, and have DRT of 25.8 and 18.4 Mb/s
Ok, I am assuming that your measurements are in Mega Bytes per Second (MB/s) and not Mega Bits per Second (Mb/s). Even so, I would agree that you are getting low data transfer rates.
What is the make and model of the USB HDD that you have attached to the AirPort Extreme? Is it formatted in HFS+ or FAT32?
Also, the 25.8 & 18.4 readings when you have this drive attached directly is a bit low as well. I would expect something more like: 35 MB/s (read) & 25 MB/s (write) for a USB 2.0-connected HDD.

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.

Change data transfer rate ?

Hi there,
I have installed a new WD 1tb internal hard drive in my late 2006 iMac . I've managed to get over a problem I posted about earlier namely getting the Snow Leopard disc out and using my original Tiger 10.4 discs. Trouble now is despite following the instructions for formatting my new hard drive I keep getting input\output error coming up . I've googled a lot and I believe it may be because my intel Mac supports 1.5gbs a second transfer rate whilst the hard drive is 6gbs . I have a caviar blue advanced drive that has no jumpers to change , but I'm led to believe that would be the answer . I'm relatively new to all this but are there jumpers in the mac itself ? Or is there a way to change the rate so my Mac accepts and formats the drive ? On various sites it says the drive is compatible but not how to do this. Hope it makes sense lads I'm sooo stressed .
Cheers

Transfer rate won't cause this problem. Your Mac will only transfer data as fast/slow as it can, 1.5gbs. The HD transfer rate will automatically slow to 1.5gbs.
What did you use to format the HD and what format did you use? It should be formatted to 'Mac OS Extended (Journaled)'. This can be easily done using the Disk Utility app that comes with OSX.
Usually the jumpers are for making the HD a master or slave drive. You shouldn't have to mess with the new HD settings to make it work.

Why Data Sort is required for Merge Join Transformation

hi,
In my understanding Merge Join works very similar to T SQL joins. But I am trying to understand why Sort is a compulsory requirement? I have looked into following article but not helpful
http://technet.microsoft.com/en-us/library/ms137653(v=sql.105).aspx
aamertaimor

Merge Join is going to walk through two sets in the order that you gave in your input or using the Sort transformation. So, it loads one record from one input and one record from the second input. If the keys match, it will output the row with information
from both inputs. If the left input has a value that is less than the value in right input, then either the row from the left input is sent out with no right input information (if there is an outer join) or if the join is an inner join, the
Merge Join component will get the next row from Left input. If the right input has a value that is less than the value that in the left input, then if there is a full outer join, output the right input with no left input information otherwise, get the
next row from the right input.
Here is the beauty, SSIS only needs to retain a couple rows in memory.
What if Microsoft decided that there is no requirement for sorting? Then in order for the Merge join to work is that it would load all of the rows from one input into memory and then the Merge Join would look up the row in memory. That means
a large amount of memory would be needed.
By the way, if you want Merge Join behavior without the sort, use a Lookup component.

Installed SSD but data transfer rates at 8mb/s and unresponsive

Sigh, just installed the Crucial m500 480gb SSD in my macbook pro 17" early 2011. Everything seemed well on bootup and the SSD is detected and formatted successfully. But when I run CCC, it took 2hrs to transfer 2gb.
After stopping the cloning, the SSD became unresponsive. Even disk utility crashed and cldn't start up. I had to reboot.
Then I tried manually coping a 10gb file from my existing HDD to the SSD, it started at rates of 8mb/s then dropped. It wld stop for awhile (20-30s) and continue. All the while, transfer rates keep dropping till 2-3mb/s. I stopped the transfer halfway as it was taking so long. Then the SSD became unresponsive again.
Is it safe to say that there is a problem with the SSD??
Argggg. Tks.

You might want to contact Crucial support - make sure you have the latest firmware for it too (although no available updates are listed on the Crucial site).

What are the system requirements for iMovie 11

On the product support page for iMovie, the link to the system requirements is for iLife '09, not '11 so I'm not sure if that information is correct.
Basically I have Mac OS 10.6.8 and I want to upgrade to iMovie '11, but I do not want to update the OS as a requirement.

One more thing. If you Mac cannot be upgraded to Mountain Lion, there is another option. You can go on Amazon or eBay and look for the iLife 11 Retail Package, which includes iMovie 11, along with all the other iLife Apps. You can install this on 10.6.3 and above. The downside is you can only upgrade it to iMovie 9.0.4 (I think). To upgrade to 9.0.8, you need at least Lion.

Data Transfer rate on IPLC link

Dear Experts
I have one link (IPLC) from india to african countries and the link bandwidth is 150 Mbps. This link i am using for my data transfer from servers connected on both side of the links. Now the problem is that i am able to get only 500 to 700 KBps of file transfer speed with FTP protocol even if the link is free.
The END A and END B distance would be around 9000 Kilometers and the response on the link is aroung 200 to 230 ms.
As per my past experience i have few links with in the country and the link distance is around 2000 Kilometers and the response time on the link is only 30 to 40ms. Here i use to get the file transfer speed upto 17 MBps. Now i understand that if the distance is more the file transfer may take some time but want to highlight that we are using RFC 1323 tunable settings on server NIC cards . With this RFC i should be able to achieve more then 10Mbps of the speed.
I don't have any experience on working on the IPLS link for huge data transfer so woulf need your expert suggestions on the issue. I want to achieve the maximum speed on the link if it is possible.
Thanks

I can't believe it. It's a 2 week old harddrive. a western digital suposed to be good quality.
Have I broken it or what ?
I have made a badblocks scan before trying to use it and found no problem. I'll try again but I fear loosing data any moment now :-(((
Western Digital is great but every manufacturer ships out defective drives now and again. Run a hard test with Sea Tools or the WD equivalent and if anything comes up, call them immediately. Your drive is still under warranty if it's brand new so they should replace it for free.
