This is a question for 50D users using Sandisk Extreme III or IV cards. I'm very interested in knowing how long it takes YOU to process (download) each RAW image from the cf card to the hard disc.

Currently, if I process RAW files without any adjustments in DPP and I download them at maximum Jpeg quality, 12, using a Lexar UDMA capable (for the Exteme IV, old style) Firewire 800 card reader, each RAW file takes about 13 seconds with either card. This is better than the 18 seconds it takes with a Sandisk USB2 12 in 1 card reader (model SDDR-89 V4), but it still seems a little slow. Sometimes I have 800-900 shots to process and it takes 3-4 hours.

I would be very grateful if you could all try the method above for 5 or 10 RAW files and let me know what size and type of Sandisk card, what reader, and how long each image takes.

I would also be very interested if anyone uses other cards (at least 8GB) which are faster.

Many thanks in advance.

Hi. I cant really help as i dont have a 50D but for reference, using the Extreme III cards in my USB2 card reader i get around 9-12 MB/s transfer speed.

Not all card readers are equal. The internal one in my Dell at work is about 1/3 slower.

What exactly are you trying to determine here?

The test you've described isn't really telling you much about your CF cards and/or card readers - it's really only measuring the processing speed of DPP.

On my system it takes 62 seconds to process 12 40D raw images in DPP from a Sandisk Extreme III or IV card. My card reader is USB connected and not UDMA so there is no improvement in speed using a IV card version.

If I first copy the files to the hard disk, then process them in DPP from the hard disk it takes 54 seconds.

Trust me, my hard drives are a lot faster than the card reader, so the limiting factor here is the time it takes DPP to process the image, not the time it takes to read the image from the card / hard disk.

(For the above I selected 12 raw images from the card/disk then used the 'batch process' option to convert them to JPG on another hard disk.)

Hope this helps,
Phil.

So how many seconds is that for each RAW file?

I guess that works out to be just under one a second as the RAW files are between 10mb and 14mb.

I must say im very confused about the original question, thats why i didn't think i could help.

Downloading RAW files from the card to the PC is not processing them. I think you have two different questions.

Actually i think i understand now.

Ive just done the same test as Phil above and got 60 secs for DPP to read and process 10 RAW files off the CF and 50 sec for DPP to do it form the HDD.

My post above was purly the time it takes to transfer (download) RAW files from my CF card's and not for DPP to process them.

I can't say how long it takes to download as I have never timed it,, but I know it takes almost 30 seconds each for DPP to convert and save, which to me is a very long time, Not sure why it takes so long,, might be because my RAW files from the 50D are anywhere from 17 megs to 24 megs each. DAve

Sorry if I didn't describe the test clearly enough. It's this:

Put cf card in reader.
Open DPP and look at the card.
Select say 10 RAW images.
Choose the batch process option to convert them to Jpeg on the hard disc.
Choose the best quality Jpeg, i.e. 12.
Click 'execute' and see how long it takes.
Then work out the number of seconds to process one RAW file.

It may be that it is DPP that is the limiting factor rather than the speed of the card or reader.

40D RAW files are somewhat smaller than 50D RAWs. On average a 40D RAW is about 12.5MB and a 50D is about 19MB so a test with 40D files isn't comparable.

Yes, thats the same test i did earlier. I would say DPP is the limiting factor. Or probably more the PC itself but considering i can actually download around one file a second to my PC then its the processing side and not the transfer thats the issue.

With the tests i did above there was around 10 sec difference between downloading first and converting directly off the card. That would account for the 10 secs it takes to actually download the 10 RAW files.

Might I ask what the benefit is to convert raws straight from your CF card? Can I assume that you then throw away the raw files and keep the converted jpgs? Wouldn't it be far better to just shoot jpg in the first place?

I exclusively shoot raw unless I have a problem with a lens and need to test it. I copy the files using a sandisk extreme reader at about 12MB/sec which is about 1 raw file per second.

I use lightroom on a core 2 duo processor (E6550 at 3GHz) and it churns through about one to three files per second converting to jpg (40D) while dpp takes about 10 seconds per file. It always amazes me how well LR seems to be optimized and how badly DPP performs.

Why don't you use the camera itself as a "card reader"!?

When I owned my 350D (XT) I used to take out the CF card, plug it into my card reader and then copy the files to my harddrive... I did the same thing with my 40D when I got it, but one day I had forgotten my card reader elsewhere and had to use the 40Ds USB connection directly, and WOW it was MUCH faster than my old 350D and even faster than my card reader! 8 GB in just about 15 minutes!

I'm not going to use a card reader again unless i get UDMA cards and a UDMA card reader..!

Processing I use Capture one so I can't really compare, but it takes about 3 seconds per RAW image. I have not tried DPP at all since i started using Capture One, have not tried Lightroom yet either but i may try it some time.

I have a Core 2 duo E6850 btw. (3 ghz dual core) and it was a great improvement on the speed front over my old singlecore 2.2 GHz athlon, I'm down to maybe 1/5 of the processing time.

No, I don't throw away the RAW files. I do bird photography inc. birds in flight (BIF). As anyone who does BIF will know many shots will be useless, OOF, bird only half in frame, etc. So what I do is convert them all to Jpegs, look at them on the monitor, delete the ones that are not acceptable (often 90% - I have high standards) and then copy over the RAW files that go with the 10% I keep.

It's easier to copy the 10% of RAWs that go with the keepers than to delete the 90% of the RAW files I'm not keeping.

Thanks for your reply.

That's very interesting. Maybe the 350D was USB 1, which was quite slow and the 40D is USB2 which in theory is about 10 times as fast. I'll try a direct download next time but if DPP is the limiting factor I'll just have to wait.

Thank you for replying.

Actually no, 8GB in 15 mins is slow compared to a proper USB2 card reader.

As ive said above, i get around 10-12MB/s form my card reader. I have used my 40D once or twice and it averages around 2-3MB/s. Not tried it on any other PC other my my home one though but i think you will find its nowhere near full USB2 speed. And yes, this was using a USB2 port.

Thanks, Phil in OZ. I think you're right. DPP is the limiting factor. Maybe I need to look at them in DPP first and weed out the obvious duds there. That way there will be far fewer photos to copy / convert so the whole process will be quicker.

Many thanks for your reply.

Had a look at your homepage and saw your pictures of house sparrows. Were they introduced? They're surely not native.

Plenty of space on the HDD, Joe. Also, I thought fragmentation occurred when you edit a file several times on the HDD and it gets bigger? When first copying, they are unlikely to be fragmented on a HDD with plenty of space.

I do, however regularly defragment the disc.

Thank you for your reply.

Seeing as you can review your RAW files just like jpgs in DPP i cant see how its quicker to go through the conversion to jpg first.
You still need to wade through all the RAW files to delete the bad ones.

Actually 8GB in 15 minutes is around 9 MB/s!

I use Sandisk extreme III cards btw. Of course you won't reach full speed USB2, that's 400 Mbit/s (roughly 50 MB/s theoretical). The flash cards are not that fast, yet.

Sure it can be done faster with a dedicated high speed card reader but 15 minutes won't ruin my day! :)
