Slow File Transfer Death

[shmoes]

Hey all,

I have Vista 64bit and I'm connecting to a 1tb terrastation.

I've been trying to move files off the terrastation as it's been giving me issues and I don't want things crap out.

Well the terrastation only has 600gb of data on it, and i've been transfering since last week. As it turns out I discovered that using an FTP program is a little more reliable then a direct copy.

What i've noticed though is if I restart my computer and transfer I get lightning transfer speeds for about 2 hours. Then it drops to a dead crawl for no reason. There is no other real network usage and no reason for the crawling speeds.. Once I restart the computer again I'm good to go for a while..

MSKB says there was a hotfix, and a fix in sp1, and since i'm running sp2 there shouldn't be an issue..

any ideas?

RAM or CPU usage?

Ram and CPU usage are nominal

When you say that it has stopped to a crawl, is it still actually transferring data or is it just using the progress speed indicator to average your speed from high to zero over a length of time?

What is the cable connection condition like, do you have another piece of cable you can try?

Is the stopping of transfer based on any timeout setting in that it occurs after the same amount of time?

You did say you were replacing this Terrastation maybe this is just a natural progression from a faulty Terrastation?

What errors or trouble did you have with any "direct copy"?

I've tried multiple pieces of cable and no change.

connecting directly over the network \\192.168.xxx.xxx it takes an extremely long time to discover files and even browse the folders. When copying it says it's transfering at about 100KBS and it too about 24hrs to transfer 20gb. I never got any errors but the transfer window would just disappear and i'd have to reselect and copy.

I have not tried connecting directly with a cross over cable. But I realy shouldn't have to..

Now with the FTP program (flashfxp) for the first while it transfers at about 5 - 8MB/s lightning fast .. then it also drops down to the 100KBS once I restart, it starts again.. I have no idea where i'd find a timeout setting..

I thought it might be the terrastation..but recalled slow transfers between my two computers (vista and XP) at the time I thought the OS difference was the problem.

One thing to note is that the terrastation uses a linux file system.

Hi,
have you tried mounting the Windows file system on your Linux box and copying that way?

Or using smb://

I don't remember for sure, but it seems I read reviews of this being an issue with Terastations in general - slower transfers than other NAS boxes.

I'd wonder if it could be an overheating issue in the NAS box, since those are usually kind of small. Could you place a desk fan or something in front of the terastation during the file copy, in case it's just getting too hot? I mean, 600GB over ethernet is a fairly large transfer, if you're tryign to do it all at once.... especially if any hardware is failing.

Even with all Gigabit ethernet connections (unless possibly you have a faster LAN connection vs WAN... such as a ...1000/2000 connection instead of just 10/100/1000), you'll be getting theoretically 125MB/sec (1,000mb/sec) at absolute max throughput, if nothing else is going across your network. If you've got a 10/100 connection anywhere in the mix, then you shouldn't expect more than 12.5MB/sec(100mb/sec).

Sometimes, transfers seem to start off faster, and then end up slower, but that can often just be the appearance of the transfer, or either that some of the data was already cached, and therefore WOULD be faster.

Also, you could try an alternative file movement program on the Windows side. TeraCopy has some great features overall, and in general, (especially with large file transfers like this), it does performs much faster and more efficiently than the standard Windows Explorer transfers. Also, you could try an alternative FTP app. Take a look at FileZilla. It's a VERY good program, is free, has Linux and Windows versions, and is very fast. I use it sometimes for uploading large audio files to a web server.

Another piece could be your router. If your router has any age on it, this is going to put a hurting on it as well. I'd imagine it could be getting pretty hot and exhausted as well. Try another fan or just the same fan, depending on location, in front of it as well. Your router, is after all, a tiny computer, generally with no fan.
