Just curious as to what speed SD card I will need for this baby once it comes in. I can get a 60x much cheaper than a 133x ... I was checking out these two cards, mainly because I have used Corsair without problems before:

Or even this 4 gig card:

I trust Newegg, they will accept returns without any hassle. Great company!
But anyways, let me know aboutt hese cards, so I can order one :D

I recommend Sandisk brand cards as the best after having used about 500 cards of many different kinds. Other brands have more read errors. The standard (slower and blue) model of sandisk is what I use, they work great and are recommended. Faster cards give no benefit and cost more.

sleepypedro says the transcend will work in the other thread

Anyone have any experience with A-data 50x cards??? I found deal this morning!! 2Gb... 37.99, but I was unsure about the speed of the card since it is 50x.

Just a quick edit:
I went ahead and bought this Transcend card: http://www.newegg.com/Product/Product.asp?Item=N82E16820163158
Had 150x, and great reviews... Plus I heard that Sleepypedro has had no real problems from that brand. :)

... other than not being able to format the card with the r09 unit with the current firmware.

The R-09 records two channels at 24/48. That's 2.3Mbits per second of data
(24 bits per sample * 48,000 samples per second * two channels = 2.3 million bits per second)
Flash card speed is rated in relation to 150,000 bits, so 1X = 150,000 and
20X = 3 million bits per second. This is the maximum transfer speed when
reading from the card under optimum conditions. Writing to the card takes longer.
A good rule of thumb is to get an X rating that is double what you think you'll need.
In the case of the R-09, you need 2.3 million bits per second = 15.3X So I think
you'd be safe with a card rated at double that rate, or 30X. Actually, it's not
easy finding an SD card rated slower than 30X, so I think you're safe with the
A-Data card.

I spoke with Roland Tech Support and they said use standard speed SD cards only, because the faster cards use "bursting" to write data. You need a steady stream for the R-09. I have a SanDisk 2GB in mine.

How do you format the card? a card reader?

yep....look at the thread that gewwang references above. :)

Hm, I could never imagine that using a faster SD card would give adverse results. If this is an inherend flaw of the SD card architecture, it must be documented somewhere on the net. Like, is there a hard limit between cards who employ burst writing and those who don't? At 30x, 50x, 66x? Links, anyone?
I often hang out at Rob Galbraith, who is a memory card guru when it comes to digital cameras. AFAIK, I never saw him mention this (mis)feature. Read more about SD cards here:
http://www.robgalbraith.com/bins/multi_page.asp?cid=6007
Another specification which may or may not be important to you is the SD>computer write speed. Obviously the faster the better if you plan to transfer the data in the field, perhaps to an OTG standalone disk. Check out Rob's (slightly outdated) recommendations an the last page above.
Another factor that hasn't been discussed is durability. SanDisk Extreme III are guaranteed to work in a wider temperature span, and primed for shocks and vibrations. Before picking up other brands, check the working environment specs:

I just ordered a R-09 from samash.com and was wondering if anyone has tested the R-09 with Transcend 2GB Secure Digital cards?
