Real world times for RH1 sp uploading

[orangezero]

I've read one or two reviews a while back, but was wondering if anyone had any idea on how long it does actually take to get a normal MD recording uploaded into SS with the RH1?

Also, any speed increase with pcm uploading (originally from linein with mics)?

I ask because it seems to take forever to upload and convert to .wav. No other devices on usb to slow it down. I just expected it to be faster.

I thought I heard the number of around 10x realtime for SP uploading, but does this include the startup and conversion as well?

For instance, would it really only take 5 minutes to get a 50minute recording uploaded and transfered to wav format? or would it be more to do all that?

I have probably 60 or 80 standard MDs that I would like to backup and have better access to but I'm a little leary of the time it will take to do it all.

thanks,

Marck from MDCenter.nl did some testing earlier this year - the results can be found in his review here:

SP => PCM should be quite a bit quicker than SP to Hi-SP.

Maybe some of the people here who have recently acquired this unit can give some updates.

yeahs, thats the review I was talking about. I was looking to get some realworld experience before plunking down the money. Plus, no one seems to want my rh10 either...

Ok, I wasn't sure if you had seen that or not. Quite a few people on the board now have the RH1, so I'm sure we'll have some feedback soon - or if not you could try sending a PM to one of them to try and get their thoughts.

thanks for the pm, no problem.

Never said thanks for point out the review either. I've been waiting for this for a while, as have most i assume. Hope someone can pull away from their's long enough to shed some light.

take care

ok guys, here are some figures, hope my world is real enough for you:

AMD Athlon @ 2.0 GHz

XP home / SonicStage 4.0

USB 2.0

The source is a SP-MD of 57:42 / 30 tracks, which originally was copied from a CD through line-in.

I ran three rounds, each of them included conversion to WAV after transfer:

A: SP-PCM through a 4 port USB 2.0 Hub with a webcam connected (and other devices on the other USB plugs on the computer).

B: The same with the RH1 connected directly to the computer, all other USB devices disconnected.

C: SP-256 Kbit, through the Hub etc.

The percentages given next to the times are CPU-load during the procedure.

Run | transfer time | conversion time | total time

A | 5:55 / 40-50% | 2:05 / 10-100% | 8:00

B | 6:07 / 40-50% | 2:19 / 10-100% | 8:26

C | 8:28 / 50-60% | 1:01 / 100 % . | 9:29

It seems, that the RH1 is not affected by other devices being connected on the USB ports. The slightly longer time in run B could be explained, that the unit had to spin up first before the transfer could start, which - if I remember correctly - was not the case in A, the RH1 was already spinning. It also had to spin up first in run C, so maybe B and C are a better comparison. Why converting also took longer in B I could not tell, it only confirms my theory, that computers never really do the same thing twice, even if they could be expected to do so...

Transfer to PCM is faster, while conversion from 256Kbit is faster on the others side; it's interesting, that the CPU load was shooting up and down from 10-100% while converting from PCM to WAV, but just went straight up to 100% and stayed there, when doing so from 256 Kbit. Probably this has to do with the reading speed of the HD? (which is a SATA 2, of which I honestly don't know if it really performs 300MByte/sec, I actually doubt it)

I have probably 60 or 80 standard MDs that I would like to backup and have better access to but I'm a little leary of the time it will take to do it all.

So if you take roughly 10 minutes for one MD60 (provided, your computer is not all too old), you end up at ~ 13.20 hours of working time for 80 MDs, sounds like it could be done in a weekend, if you avoid editing titles etc.

About computing speed in general, I basically can confirm the figures of Marck from MDCenter.nl. He states 10x for SP-PCM on a Pentium IV @ 2,8 MHz, my computer is somewhat slower (and a different CPU) and it performs at 9,75x, which is close enough; maybe Marck brought his numbers to a round figure, which might lead to the conclusion, that even processors at slower speed than my 2.0 GHz might do the job at 10x, as my CPU was only busy at about 40-50%. I guess the bottleneck is still the USB port. But this is all guessing, maybe someone with a machine at 1-1,5 GHz could drop a few figures here...

Hope this makes sense to you,

cheers, r.

That's about on par with my experience. I uploaded a 73 minute long disc yesterday-- actual upload took about 7 minutes, then it took another minute or so to convert to "wav"-- between 8 and 9 minutes overall.
