Re: USB recording media recommendation for UFX - pen drives etc.

Hot? Or maybe it needs some more free space or a SSD Trim?

Re: USB recording media recommendation for UFX - pen drives etc.

Maybe a Sync Problem between the hooked Octamic D had been the Problem.
The ssd-housing was less than hand-warm.

Or the typical Windows samplerate change Problem.

One more test over 1,5 h with 16 Ch.@24/44.1 ended up perfectly (no error, correct multiple-Files).

Can Windows change the samplerate, eventhough the ufx being hooked up with asio (samplitude) @96kHz?

The Problem is that Windows often switches modified Things back after updates…

The housing is really fine, the indication of usb 2.0 or 3.0 with the Color of the LED is a nice thing 2 have in this application.

Re: USB recording media recommendation for UFX - pen drives etc.

Samsung tells me:
"
-    SSD-Trim aktivieren:
[Win7/Win server 2008 or later version]

**** - FAT32 is not supported ****; NTFS is supported
-TRIM cannot be done, but Enable/Disable is possible.
- Enable TRIM in Windows : fsutil command   ...
"
So it seems, trim has no effect on FAT32-Partitions. But it should be no Problem to delete and reformat the Partition before the new recording session. OK, al little bit oldschool hammer method :-)

Re: USB recording media recommendation for UFX - pen drives etc.

Which external SSD works with the UFX II / UFX+?

Crucial has a new model X6:

Has anybody information if this would work fine?

But it seems my ssd, an old Samsung 840 model, did not pass Long time testing. it stopped after 2 hours 24 ch. 24/41.1 and now stops every try after About 2 min. recording and starts to re-initialise hdd. very sorry, are there prooved ssd's on the market?

Did you find an SSD that works?

RME have repeatedly claimed SSD's generally work fine with the latest DUREC but there are examples on the previous page of this thread of models that fail. 

It would be good to have an official recommendation for full recording capacity please!

Hello
Some recommendation of USB stick model & size for an UCX II ?

Re: USB recording media recommendation for UFX - pen drives etc.

@Matthias: so these would work .. ?

https://www.amazon.de/-/en/SanDisk-Extr … 1&th=1 €38,99 (€0,30/GB)

The products of higher capacity are cheaper in terms of price/GB, ~€0,23 and 0,24, cheapest the 256GB variant:
https://www.amazon.de/-/en/SanDisk-Extr … 1&th=1 €58,99 (€0,23/GB)

Even less expensive is this product combination of 256GB microSDXC card and reader:
https://www.amazon.de/-/en/SDDR-B531-GN … 5&th=1 €52,98 (€0,21/GB).

If my calculation is correct, then it should be possible to record with an UFX+ 80 DURec channels @44.1 kHz for ~6,6h (note: I calculated the netto capacity to be approx 91,25%):

Re: USB recording media recommendation for UFX - pen drives etc.

The SD cards that I used/tried were not able to record 80 channels, but either 74 or 76. Otherwise they worked perfectly, and as no one uses so many channels they are a recommended and cheap solution. For full 80 channels one might need V90 specification, but such SD cards are very expensive and then have no advantage over an Extreme Pro or similar.

Re: USB recording media recommendation for UFX - pen drives etc.

Ok perfect, many thanks. Then USB Stick, then I can use it also very flexible for PC.
I hope that the 256 GB Model has the same good controller like the 128 GB model, that you tested.

Re: USB recording media recommendation for UFX - pen drives etc.

I tested now two Sandisk Extreme Pro sticks against my old one from 2014:
UFX+, 80 ch. selected @44.1 kHz. Test time around 22 minutes for a 1st impression.

Note: the 2GB filesize are reached in ~00:06:45.
MADIface Driver: 0.9735, Firmware: SW v46

Preparation of media:
A) start cmd window with admin rights
B) wipe stick and create new/empty primary partition using Windows 10's diskpart tool
    diskpart
    list disk                 <--- identify the disk number/id of the USB stick
    select disk N     <--- replace "N" with the disk number in your case (from previous steip)
    clean
    create par prim
    exit

C) format primary partition as FAT32 (with a default clustersize of 64 sectors) using h2format (from C't magazing):
     https://www.heise.de/download/product/h2format-40825
     h2format.exe V:  <----- replace "V:" with your volume"

Important for the formatting using h2format: it seems to be required to use the default cluster size of 64, because when I formatted with 32, then the DURec recording stopped several times after a few minutes.

Re: USB recording media recommendation for UFX - pen drives etc.

Test passed for the 256 GB model, cool.

@Matthias: recording stopped at the 100th file, but there are still 38,56 GB free on the volume of the stick.

Would it perhaps be possible to extend this a bit by e.g. using three digits as counter for the 2GB multichannel wave files?

If DURec can write 100 files UFX01_00.WAV - UFX01_99.WAV why not 200 or 300 or 1000?

I think the RME batch processor software wouldn't get any memory problems, because it does not need to keep whole files in memory to convert the multichannel wave to different files..

I think if you record fewer channels, that you are quicker limited by the 100 file limit compared to disk space on a volume.

Re: USB recording media recommendation for UFX - pen drives etc.

I have to point out that this 100 file limit is for an ongoing recording. Who needs more? Every time you start a new recording the counter also starts again at 0.

Changing that would also mean updates required for all tools, software and the firmware of four devices. Lots of work, and IMHO not worth it.

And it's the other way round: the more channels you use, the quicker you write 100 files.

Basically 100 files of 2 GB = 200 GB max recording capacity. You can calculate that back on how much time in recording you get at low, medium and max channel count.

Re: USB recording media recommendation for UFX - pen drives etc.

The reason I asked was a use case to be able to record an event over a longer period of time and do the editing afterwards in a DAW. A friend of mine has sometimes already life events over 4h, that would be covered.

Now where I noticed how stable this runs I simply had the spontaneous idea, what you would think about such an extension. Sure, tools would need to be changed.

But thinking longer about this and reading your comment I have to admit, that I would even not be 100% sure, whether a DAW could handle such a big file and file operations might need a lot of physical and virtual memory so that my "spontaneous idea" might even be a bad idea. Ok, maybe not so cool than I thought initially.

Anyway, many thanks Matthias for your work and efforts / this video and having informed about these wonderful USB sticks, very useful ! :-)
