Fastest Sandisk Memory Card?

This has been discussed before, and the situation may be changing with new firmware someday, but right now Ultras are faster to write to in the M9 than Extras, although uploading to the computer is a little slower with Ultra than Extra. But Ultras cost much less, so I am using them..

8 GB SanDisk Extreme III... $29.00 USD at Amazon.

 

This changes daily. And Amazon is constrained to not ship cards across international price boundaries, like out of the US or out of the EU. I'm still paying $70 for a 16 GB Ultra class 4 card (the latest, with 15 MB/sec upload speed) at my Israeli duty-free airport store. Here are the SanDisk choices at Amazon this morning (in US):

 

16 GB Ultra II class 4 (15 MB/sec) not the lastest mfg, as the II is still showing on the label, $38.23 $2.40/GB

 

8 GB Extreme III class 6 (20 MB/sec) not the latest $26.95 or $3.37/GB

 

8 GB Extreme class 10 (30 MB/sec) the latest $53.98 or $6.75/GB

I use 4 GB cards, and I have SanDisk Ultra II, SanDisk Extreme III, and Lexar Professional 133x. I get the same results with any of them in my M9. It takes about 3 to 3-1/2 seconds to write a compressed DNG, and about 4 seconds for uncompressed.

The Leica's interface is probably the gating factor here.

 

I have tried Extreme III 30mb/sec, Extreme II (15 mb/sec.), Transcend SDHC Class 6, and Ridata SD 150x, and seen no difference in write performance on M8, or M9.

 

I just used a set (9) of 8gb sandisk extreme III 30mb/sec. cards in both M9, and M8 on a trip to Turkey, Cyprus, Israel, Malta, Egypt, Tunisia, Crete, Spain. I tested thoroughly ( I got the M9 5 days before the trip ), and everything worked flawlessly both before and on the trip.

 

The 8gb Sandisk extreme III 30mb/sec. cards are now my standard for both SDHC (Leica), and CF (Nikon) use, as I think they represent the 'sweet spot' for cost/ performance.

 

I doubt if a faster (extreme IV) card would make any difference on Leica, since I believe that the camera's interface s not up to to 30 mb/sec.

 

The difference on a Nikon D3 and 3x is not worth thinking about.

 

Extreme III clears a 35 frame buffer in 5.5 sec.

 

Extreme IV clears a 35 frame buffer in 4.5 sec.

 

Buy Sandisk from photo dealers (like Adorama) rather than Amazon since Amazon purchases are not eligible for Sandisk's best rebates which drop an 8 gb Extreme III 30mb/sec card to about USD $29.

 

I hope this is helpful.

 

Regards ... Harold
