Jobo SD/SDHC to CF Type II Adapter

My M9 arrived 8 days ago - and I have started to use it - its a new experience for me, first Leica, first rangefinder, and I'm still in ecstasty. I found that my ancient SD readers would not read the SDHC cards. I have a Sandisk Extreme Sandisk Extreme Firewire Card Reader and I couldn't find a SDHC Firewire card reader so I thought I'd get the Jobo SD/SDHC to Compact Flash Type II Adapter. I used xBench to measure the read and write speeds and to compare this to the CF cards I have. The results are here.

I think the Uncached Read MB/sec [256K blocks] line is the relevant one for memory cards (correct me if I'm wrong).

 

 

Conclusion:

The Uncached Read Speed (256K block) seems somewhat linear to the card speed.

Considering that the SDHC card is rated at 15 MB/sec the read speed is acceptable.

 

I am wondering how fast the USB2 SDHC Card Readers are?

 

Cheers,

I have one of these same type adapters by another company. I can't say if they are any different and whether they are simply a pass through device or have any eletronics that effect transfer or rear-write speeds.....but the one I am using is somehwat slow. In other words if I put a relatively fast SDHC card (class 6) into the adapater and then into a NIkon D3 DSLR....the read-write speeds are noticably slower than most generally fast CF cards I use by itself in the Nikon D3. No scientific tests, just a general observation. I was under the impression that these adapters were just a pass-through, but apparently not. I'd like to try the Jobo one to see if there is any difference in speed to the one I already have.
