I have briefly tested the following set up - shooting some 1080 30P (HQ) and has worked fine so far. Here are the test numbers they are a bit different from a previous test with the same hardware.


Transcend 16GB SDHC TURBO CLASS 6($50) and Kensington adapter:

Sustained data rate: Read: 19.16MB/s Write: 14.59MB/s
Random 512K file: Read: 19.19MB/s Write: 2.48MB/s
Random 4K file: Read: 4.48MB/s Write: 0.022MB/s

Tried the combo on the EX3 today no errors. You can close the memory card door on the EX3

Maybe it's buried somewhere in this thread but is the speed of the Sandisk extreme III 16 GB the same as the 8 GB?

Also - concering transfer speeds: Transfering the media from my 8 GB Sandisk via the camera and it's USB took 16 minutes. Transfering from my SxS card took about 7 minutes.
Tomorrow I'll try using my laptops built in SD-slot.

I leave my card in the express adapter and when transfering the files this may quicker, using the Express slot on my laptop.

Is estimate the new Extreme III to tranfer to your computer at 1.2GB/minute.

Yes, this slower thean SxS... But we knew it would be.

But based on this saving, you could buy a handfull of cards and copy them later when you have the time.

What?! Really?! This is awesome! You guys have done some great work on this - thank you!.

So, is this the combo you are referring to?

1, Kensington 7-in-1 Media Reader $ 36 (USD)
1, SanDisk Extreme III 16GB 30MB/s version $129 (USD)

Can anyone post links to the best place to order them from?

Ah, Good point. How about real part numbers? I just don't want to buy the wrong devices.

Update on Expresscard adapters

In the quest for finding the perfect SDHC to Expresscard Adapter here's more info:

Sonnet 21 in 1 Multimedia Reader Part #MMRW-E34: EX1 displays "Unknown Media" with SDHC card in or not

SIIG ExpressCard 12 in 1 R/W: EX1 displays "Unknown Media" with SDHC card in or not

Cables Unlimited Card Reader ExpressCard 34mm (IOC9750) The packaging read SOHOUSB Multiple card reader to Expresscard: It works. Very similar (the same exact casing...) in design and functionality to the Kensington reader we all now know and love however... This card is a tiny bit faster. I noticed when I was copying data from my card to my RAID, it was maybe 10% faster. I did some benchmarking (using some Mac freeware, Xbench, and here are the differences:

Kensington Adapter:

Description, Overall Score, Detail

Disk Test 2.20
Sequential 20.87
Uncached Write 21.71 13.33 MB/sec [4K blocks]
Uncached Write 23.92 13.53 MB/sec [256K blocks]
Uncached Read 13.16 3.85 MB/sec [4K blocks]
Uncached Read 35.94 18.07 MB/sec [256K blocks]
Random 1.16
Uncached Write 0.31 0.03 MB/sec [4K blocks]
Uncached Write 5.95 1.91 MB/sec [256K blocks]
Uncached Read 522.34 3.70 MB/sec [4K blocks]
Uncached Read 95.21 17.67 MB/sec [256K blocks]

SOHOUSB:

Disk Test 2.24
Sequential 24.61
Uncached Write 21.93 13.47 MB/sec [4K blocks]
Uncached Write 26.61 15.05 MB/sec [256K blocks]
Uncached Read 18.77 5.49 MB/sec [4K blocks]
Uncached Read 38.38 19.29 MB/sec [256K blocks]
Random 1.17
Uncached Write 0.31 0.03 MB/sec [4K blocks]
Uncached Write 5.91 1.89 MB/sec [256K blocks]
Uncached Read 497.94 3.53 MB/sec [4K blocks]
Uncached Read 101.12 18.76 MB/sec [256K blocks]

Not sure why there are differences or if one is better on the EX1 or not. The SOHO had 15% higher sequential read and write scores than the Kensington, and about the same random write and lower random read scores. Anyway this adapter is the cheapest of the lot at $16. I'm going to order 1 more just for fun.

And also just for fun I decided to put the Sandisk Extreme III SDHC card in a Sandisk Micromate SDHC usb reader I have and measure the scores, very similar to the Expresscard adapters:

Disk Test 2.15
Sequential 15.61
Uncached Write 13.97 8.58 MB/sec [4K blocks]
Uncached Write 15.05 8.52 MB/sec [256K blocks]
Uncached Read 15.22 4.45 MB/sec [4K blocks]
Uncached Read 19.06 9.58 MB/sec [256K blocks]
Random 1.15
Uncached Write 0.31 0.03 MB/sec [4K blocks]
Uncached Write 5.43 1.74 MB/sec [256K blocks]
Uncached Read 455.42 3.23 MB/sec [4K blocks]
Uncached Read 51.02 9.47 MB/sec [256K blocks]

And just for reference here are the scores on a 8GB SxS Card (a LOT faster):

Disk Test 4.88
Sequential 54.65
Uncached Write 66.40 40.77 MB/sec [4K blocks]
Uncached Write 77.70 43.96 MB/sec [256K blocks]
Uncached Read 25.99 7.61 MB/sec [4K blocks]
Uncached Read 147.30 74.03 MB/sec [256K blocks]
Random 2.56
Uncached Write 0.67 0.07 MB/sec [4K blocks]
Uncached Write 13.67 4.37 MB/sec [256K blocks]
Uncached Read 977.79 6.93 MB/sec [4K blocks]
Uncached Read 392.66 72.86 MB/sec [256K blocks]

Got my Kensington and sandisk 8gb today, it all works ok.
Just want to confirm though that the Maplin SD>Express reader does not work.

So Keith,
will the Cables Unlimited Card Reader ExpressCard 34mm (IOC9750) allow the EX1 memory compartment to close?


Here's a quick test to determine if the Cables Unlimited Reader is a bit faster in the EX1:

Set the EX1 to 720 24P S&Q ON at 40 FPS. (Almost half speed)
With the Kensington, I had no errors. I tested it for about 5 minutes.
It failed when S&Q was set to 45.

Check to see if the Cables Unlimited Reader will run at S&Q set to 45. If so, incrementally increase to determine when it fails.

Thanks for the update!
