GRD RAW writing speeds. Test of various SD cards

Postby odklizec » Sun Aug 12, 2007 12:15 am

Hi folks,

I know many of GRD users refuse to use RAW, because it's slow to write. Well, yes, it's not the fastest thing on GRD ;) But in my humble opinion, the RAW at ISO800/1600 provides much better results (if well processed) than the same ISO speeds in JPEG. But the GRD RAW writing speed is terribly slow. And endless circle...

So, because there is not much that can be done with this problem, the GRD guys at DPReview Ricoh tried to summarize the RAW writing times for different SD brands & sizes. The results can be seen here..

Code: Select all
The "# BLINKS" is just the number of blinks of the camera AF led light.
This light apparently shows also the GRD writing progress.

[sorted by number of blinks]
SD .............................................................. # BLINKS / TIME (secs)

1GB TwinMos Ultra-X 150x (3:2 RAW + n640) .............................. 13/NA

1GB Lexar Professional 133x (RAW + N640 JPEG) .......................... 14/NA

2GB Lexar Pro 133x (FW2.40 RAW + N640) ................................. 14/NA (NEW)

2GB Panasonic Pro High Speed class 6 (RAW+N640) ..................... 14-15/8.8

2GB Panasonic Pro High Speed class 6 (RAW+Fine) ........................ 17/9.8

1GB TwinMos Ultra-X 150x (4:3 RAW + n640) .............................. 15/NA

1GB Panasonic Pro high speed (RAW + N640) .............................. 15/NA

2GB Lexar Professional 133X (RAW+jpeg 3264) ......................... 15-17/NA

2GB Panasonic Pro High Speed class 6 (RAW+N640+B&W) ................. 16-19/~9
[RAW+Fine adds about a second].

1GB Panasonic Pro high speed (RAW + Fine) .............................. 17/NA

2GB Lexar Platinum II 60 x ............................................. 17/NA

2GB Kingston Technology SD (RAW + JPEG on N640) ........................ 17/10

1GB Sandisk Extreme III ................................................ 18/10

1Gb Transcend 80x (RAW + N640) ......................................... 19/11.5

1GB PQI High Speed 150 ................................................. 19/NA

2GB Transcend 150x (FW2.40 RAW + N640) ................................. 19/NA (NEW)

2Gb Sandisk Extreme III (RAW + N640) ................................ 20-21/NA

2Gb Sandisk Ultra II (RAW + N640) ...................................... 22/NA

1Gb Transcend 80x (RAW + Fine) ......................................... 22/13

2Gb Secure Digital 133x (RAW + N640) ................................... 23/NA

1GB Sandisk Ultra II with USB included ................................. 23/14

1GB Lexar Platinum 40x (RAW + JPEG on N640) ............................ 24/NA

2GB Sandisk Extreme III (RAW + JPEG on N640) ........................ 20-24/NA


It seems that the Lexar PRO and Panasonic PRO cards (with write time about 8secs) are currently the fastest cards for GRD. 8secs is still not great, but much better than 12 secs or more? ;)

BTW, if your GRD can write RAW under 14 blinks/8 secs, don't forget to tell us about it! There are rumors, that the GRDs from the newest stocks are a bit faster than the old ones! But even if your card is not the fastest card, please, drop your # of blinks/times here too! It would help the other people not to buy SD cards, which are not suitable for RAW.

Also, it definitely matters if the RAW is taken with FINE or N640 JPEG and also the other images processing (like B&W, contrast and saturation) affects the writing time. It's a pity there is not an option to write just RAW without JPEG. I'm sure, it would also speed up a bit the GRD RAW writing ;)

Hi,
you mention not being able to choose RAW only, well here's a strange thing, it seems I can, unless i'm missing something here. :roll:

When I go into Menu>shooting settings> Pic Quality - the first choice I have is RAW [8M], then RAW 3:2 [8M] then F 3264 [8] and so it goes, I can't seem to find any option for chooseing the size of a jpg file to be attached with the RAW ! So when I choose RAW that's all I have (i think !!!!).

Any thoughts on this ?

The JPEG should be always created with RAW but now you should be able to set its quality. As far as I know, you need GRD FW 2.20 or higher to be able to set RAW/Jpeg quality (in Setup menu)..

Here is how you can check your current FW and install the latest one..

I didn't see any mention anywhere that the GRD supports HC SD cards. Can I assume that cards larger than 2Gb are not supported? In the manual it says something about using "high-capacity" card if you need to store more pictures, but I dont think they mean SD HC.

I'm using a PQI 1gb high speed card, so it says, but RAW took 19 blinks still.

Unfortunately GRD does not support SDHC cards. There are some 4GB non-SDHC cards, but the people who tested them says that GRD reports 2GB of available space. So it seems even the non-SDHC cards > 2GB cannot be used with GRD.

By the way, if the PQi card in the list above is from my posting. I just checked the card and it says "High Speed 150", which I take to mean 150x.

1GB TwinMos Ultra-X 150x
4:3 RAW+n640 = 15 blinks

Hi norrinradd and welcome here! I'm sorry to disappoint you, but GRD is definitely not SDHC capable. Not even with the latest FW.
