p.1 #1 · Slow Raw Writing Camera

I have an Olympus C8080 Camera that I have been using mostly with Jpeg's recently I decided to switch over to shooting Raw, but after the Raw shot is taken there is a BUSY SLIDER BAR that seems to take maybe 10 seconds or more! to write the file. Is there any way of speeding this up? or is a new camera my only option.

The camera is running on almost 5 year old technology. On a quick read of the Imaging Resource review, it seems there is no buffering of RAW files, so it does take a long time - they reported 13.9 seconds per shot. Not sure there is much you can do to speed that part of it's operations up.

Thanks for your help Craig, just curious what is the write time of the newer DSLR's

My XT takes about .3 seconds to write to my cf.

Many dslrs can maintain continuous or long strings of shots at their full rated frames rates, 4-5 and even up to 8 frames per second. I've never noticed a problem in the shooting I do that I've filled the buffers and slowed my shooting. Of course, back with my old Fuji S602, TIFFs were glacial. The D200 I have is tested (IR again) at .28 secs in single shot mode RAW for 22 shots before it slows to 1.9 secs per shot. Depending on RAW modes, the D300 is faster.

Uh, you've got a messed up camera if it takes 1 second. You should be able to plug off 5-10 raw files in a second.

Not quite.

You might be able to write to the camera's buffer that fast, but the buffer isn't clearing to the CF card even remotely that quickly. Look at this sample table for the D3, for instance, to see what kind of write speeds the camera is actually achieving:

The question isn't how fast the buffer is, but how quickly the buffer is clearing to the CF storage.
