I have cache drive and speeds used to be 20-22 MB/s from the BD burner to the server.

 

Something happened and they are now between 6 and 8 MB/s

 

I've tried copying a large single file from the computer to the server to check the network cables/routers and the speeds are gigabit (90-100 MB/s).

 

This tells me it's between the drive and the computer.

 

The question is: would the drivers for the ports have gotten screwed up somehow?

 

Could it be the drive? Any suggestions on how to test the drive? It's the LG drive everyone around here has and loves plus I've used for months with faster speeds so I know it's not rip locked.

 

Or .... is it most likely the USB 3.0 cable?

 

I'm at a loss here.....

Have you tried ripping directly to your PC from the burner and not over the network to the server?

Thanks for the suggestion.

 

So.... it seems that from the optical drive to the computer hard drive the speeds are back and stable. What the heck should I check now?

 

I can transfer from computer > switch > to server at max gigabit speeds, but not from optical drive > usb 3.0 connecting optical driver to computer > switch server

 

Definitely need some help on this one. I'm now even more lost than before.

I never copy from my burner to the server and never would. Yes I know many users do but I have read many posts saying it is fraught with possible errors. I rip to my laptop and then send it to the server. I don't use a cache disk as Im happy with the 12 minutes it takes to copy a 25Gb file over the network and the data is backed up with the parity then.

Could it be something to do with the cache disk being full and the burner writing it directly to your server and bypassing the cache disk? Do you have a disk in the server playing up? Do you run regular parity checks and monitor for errors.

I researched and then double checked and the clear consensus was rip to the server directly. What type of errors do you speak of? I'm curious. I have not noticed any issues with playback.

 

I have a rather small, and almost full, SSD in my laptop so sometimes it becomes a bit of a hassle due to space.

 

To answer your questions -

 

The cache disk is set to transfer files every night at 3:40 am. I can write directly from laptop to server at max speeds, so wouldn't that rule out full cache drive anyways?

 

Disk in the server playing up? Does that mean playing a movie or being used by another computer etc... ? If so the answer is no.

 

I run a parity test monthly, and have never had errors. I run status checks nightly and have never had an issue.

 

I also tested all my disks for read and write speed and they are all as they should be.

 

The cache disk shows empty.

 

 

I think the errors were in relation to the network dropping off without you knowing and if this would cause problems with the transfer or not. I just feel happier knowing its not going to have a drop off's between the burner and laptop drive, I have enough space for two full Blu-rays on my laptop drive and I transfer the first one while the other is ripping, thats my way and over the network may be fine for me as well. Many articles I have read in the past don't recommend it but maybe its okay now what with improved network speeds and reliability.

You also have to remember a BD drive while ripping a Blu-ray to ISO or MKV if thats what you are doing can take a long time, sometimes up to 1 hour for a full ISO and thats because of the BD drive speed and the seeking it has to do on the BD disk so maybe its only slow because of the time it takes to rip it. It could take me 45 minutes to rip a film to my laptop drive but only 15 minuted to transfer over the network. Time how long it takes to rip one film it to you PC, and then time how long it takes to rip the same film over the network. They should be similar in time.

My drive is capable of max 21-22 MB/s. It's been doing it for months.

 

It will rip a BD from drive to computer at that speed.

 

My computer will transfer it to the server over the network at that speed.

 

All of a sudden the the drive will not rip straight to the server via the computer at those speeds.

 

This tells me that the problem must be in the computer someplace. But where??

I ran a full Ccleaner and then I cleared out the driver cache per this article-

and still the same thing is happening.

 

 

I am pulling my hair!!!!!!!

 

I just tried transferring from server to computer and computer to server with files already on the server and files already on the computer. Getting max giga speeds.

 

I tried burning direct  from drive to computer and speeds are as they should be.

 

The moment I try to burn from drive to server I am locked down at low and erratic speeds.

 

I've swapped USB ports, reset the network adapter.... no luck.

 

I have no idea where to go from here. Does ANYONE have any idea what the heck is going on?? I can do or provide any anything just tell me what to do. I am stumped!!!

Hmmmmm...... no one has any ideas as to what the heck is going on?

I find my copy speed also drops by 2/3 occassionally.  Rebooting the server fixes it.

I've rebooted the server as well as tested each drive for read/write speeds.

 

I can also copy from computer to server and server to computer at the correct speeds.

I copy my BD MKVs to the HDD on my PC and then copy them over.  When I am using makeMKV some times a 25GB files will copy over in 10 min and other times it takes and hour or so.  The speed from a BD can change drastically from disc to disc depending on the number of movie segments, the sequence of the segments and the location of those segments on the disc.

I have looked into this some more for you but there are so many factors to consider. What software are you using to rip? Is it a Blu-ray or DVD? If there are a lot of movie segments on the disc it will take longer. USB 2.0 is fast enough for ripping, USB 3.0 won't make any difference. What BD Drive are you using?.

I can't ever get speeds above 9.5 mb/s using Make MKV. That's 2.2x speed, my drive can read up to 6x speed, why it never reads faster I don't know. It could be Make MKV.

As I said you need to rip a Blu-ray over the network and time it. Then rip the same movie to the PC and time it. What is the difference in time if any. DVD's always rip faster in my experience and not just because of the file size. A friend has the fastest to date, LG BD Drive and he can rip slightly faster than me, not much though. I would be interested in the time difference for a BD rip to the server and to the PC.

What's also I testing is some users using Make MKV couldn't get more than 2.2x, 9.5mb/s, even though the Blu-ray read speed is supposed to be 12x.

http://www.makemkv.com/forum2/viewtopic.php?f=4&t=4301

Come to think about it I have never seen makeMKV go faster than 12MB/s for me.  That is typically on BD that are of older movies that only have only one or just a few segments, and that is written to a drive on the same PC.

 

Unless he is using anydvd and doing an ISO which could be more efficient and get higher speeds but I haven't used anydvd since 2007 I can't really give input.

Up until about a year ago I used AnyDVD HD and a typical 35-45gb Blu-ray would take 1-2 hrs to rip an ISO using a 6x BD drive but I think from reading the post I linked to a fe post back some drive do allow your speeds and higher so Im not sure what your problem is but knowing the BD drive, format for rips, software and BD or DVD would help.

Thanks for staying with me and helping me out. Here's some info for you

 

The drive is an LG Electronics 14x Internal BDXL Blu-Ray Burner Rewriter WH14NS40. It can be found here - http://www.amazon.com/gp/product/B007YWMCA8/ref=wms_ohs_product?ie=UTF8&psc=1

 

I do use AnyDvd exclusively

 

I do rip straight to .ISO

 

I am ripping blu-rays

 

The speeds in MB/s are displayed on the AnyDvd screen, as is the time left to burn.

 

Since the cache drive install I consistently saw 21-22 MB/s burning straight to server.

 

Or in minutes- -  25-40 minutes a disc.

 

Let me know if I missed anything.

 

EDIT**** I forgot to add I've tried multiple discs and I get the same result with all of them.

 

 

 

 

Yes this is one I was looking at a few weeks back. Make MKV users get an average of 6x and up to 10x with this drive so bottom line is about 27mb/s. If you get normally 22mb/s and are only getting 6mb/s there has to be a bottle neck somewhere. Maybe as you said a faulty USB cable. Have you tried temp disabling the cache drive and writing to the array to see if you get any faster speeds. just an idea. Is your cache drive an SSD or a spinner.

I don't see how it could be a faulty USB cable because I can burn from the drive to the computer at max speeds.

 

I don't see how it could be the cache drive because I can send files from the computer to the cache drive at gigabit speeds.

 

Am I missing something??

 

 

Im lost then, as I don't use a cache drive I was going to say disable it and try and rip directly to the server to see what speeds you get. Are you writing to the PC with the rip and then over to the cache drive or directly to the cache drive.

I would say try another PC but that would be hard if you have an internal hard drive. I presume you go to the AnyDVD HD Icon and select rip to image file.

Not that it helps your post but I took over 500 of my ISO's and went to Make MKV. It was a learning curve but the best thing I ever done. Okay I can't watch 3D anymore but I really don't care. Its not just the file size its the fact that now I can use openelec on a Intel NUC and it boots in 10 seconds and 3 seconds later Im watch a film and the Microsoft MCE remote works perfect. It used to take ages before with TMT5, My Movies and AnyDVD HD loading the films, skipping the trailers and adverts and when I would fast forward through a movie it would often hang. Also I have saved over 10TB of drive space.

I could disable the cache drive easily and give it a go. That doesn't cost any money or much time.

 

I normally write directly to the cache drive, but that's where my speeds have gone to crap.

 

I can write to the PC at fast speeds, then transfer from the PC to the server at gigabit speeds.

 

I did tons of research and chose .ISOs. I like to have the original disc format. I can't watch 3D either, I'm using Dune players that don't support 3D but fully support .ISO.

Check the cache drive for SMART errors.

Check the cache drive for SMART errors.

 

Just started a long test via unmenu. Will report back. Anything specific I should post here regarding the results?

So.... How the heck do I do a SMART check? I thought I had it started in the unmenu screen, but I got no results after 24 hours.

 

 

I can't help you with that as I use drive health and the reports from it in dynamix. You could just disable it for a little while to test a bypass.
