Only HDD can be used?

[Perpetual Beta]

The answer is probably no, it will not work.

I've just checked the write speed (http://www.kingston.com/flash/dt_chart.asp) and it is only 12MB/s when Philips request minimum of 30MB/s write speed.
...

My guess: 30 MB/s should read 30 Mb/s (Megabit per second) here. Hi-Speed (USB 2.0) data rate is 480 Mbit/second brutto. Typical sustainable write speeds for external hard drives with USB 2.0 interface (Hi-Speed) are 20 .. 28 MByte/second. USB Devices with sustainable write speed above 25 MByte/s are implemented with USB 3.0 (SuperSpeed). Or limited to specific hardware.


30 MByte/second ought to be more than enough for time-shifting of a complete satellite transponder's data streams. If implemented state-of-the-art, half of the time assumed for reading.

- USB sticks capacity required by Philips sw are really too expensive (64GB minimum for pause and 250GB for recording) when compared to HDD.

That is not correct.
32Gbyte is the minimum requirement and they say 30Mb/s, but i don't know if that writing speed is available yet, It has to be usb 2.0 compatible at least.

Hi,

32 GB does not mean that 32 GB are really available - thats the reason, why 64 GB was posted... ;-)

I suggest to try a portalbe USB HDD...

Hi Toengel,
no prob.
I don't know what is available exactly.

Hi,

what I want to say is that if you buy a 32 GB stick you won't have 32 GB memory available - it's less than 32 GB!

Yes you are right.
If the set is looking that strict to available memory then it could be that you need a 64MB.
I did not test it.

Following your statement that recording with fast USB stick is possible I bought a 64 GB USB 3.0 stick and started the formating process at my 37pfl9606k_02. This process was stopped short before reaching the end status. Repeating this brings no change. In contradiction to your statement recording with fast USB stick is evidently NOT POSSIBLE.
If I'm wrong please let me know how to solve this problem.

Could you please specify the model of your usb stick?
For now we know it is a 64GB USB 3.0 but it is necessary to know write/read speed and model.
Thanks,

We had a problem with a usb 3.0 250Gbyte from a customer, wich would format, but then would not be writeable. Until now there is no solution for it. Unfortunately i can't remember the brand from the hdd.

And yes you can only use one HDD.
