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.

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

Crucial has a new model X6:

Has anybody information if this would work fine?

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

Regards

@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%):

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.

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.

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 ! :-)

Hello,
Based on recommendations reading here I purchased a SanDisk Extreme PRO 128 gig.  I cannot find a solution to format to FAT32.  Anyone have a solution?  the link above for h2format does not work. Running a Windows 10 Pro machine.  When I try via CMD, I get failure, drive to large for FAT32.
Thank you.

UPDATE:
Never mind.  I switched the stick over to a MAC and used Disc Utility.  Instant Format and works perfectly (hopefully).  So far testing with 12 channels @192kHz = sitting at 50-51%

Hi,

My Fireface UCX II says it can't read my memory card for DuRec.

I went for a combination of SC card and adapter: Sandisk Extreme Pro 128GB (recommended in a RME video or the manual, can't remember) and a ANKER USB 3.0 reader. The card was formatted on Win10 with MiniTool Partition Wizard. There is only one partition on that drive, FAT32, primary type.

Is the card reader the problem? What would I need instead? Or what might be going on?

Hi,
I would have never thought of this.
However, it did not work out.
I started PartitionWizard and the SD Card showed as a normal device with the FAT32 partition. I then deleted the partition and applied. Closed PartitionWizard. Took the drive out of the port. Put it back in. Started PartitionWizard which showed the device with no partition at all (expected). Created a new partition type primary with FAT32. Applied. Closed PartitionWizard. Took out the drive (having told Windows to disconnect the drive first).
Then I put it back into the UCX II and it again showed a "Media device error" with no memory available...

(BTW, thanks very much for taking the time on a sunday to reply - much appreciated, I am baffled..:) )

EDIT: Seeing as my notebook has a SC Card slot built in, I also tried the same procedure with the SC card only, leaving out the adapter. On the PC everything seems to have worked, but on the UCX II still the same error.

I 'delete' the partition, perform the action, then 'format' the drive. That worked every time. It did not work when doing both in one batch action, for whatever reason...

And only the SD cards behaved so unusual.

Right. And the SanDisk Extreme 128 GB stick (!) mentioned in the video is still our number one recommendation.

would it be this one now?
