I'd like to start collecting MicroSD card benchmarks. If you have bought a MicroSD card for use in your Captivate, please help out.

To test:

Install the following:
SD Card Speed Tester - Android app on AppBrain

Run it several times to make sure you don't get a fluke low number (like from momentary activity). If your phone is idle, you should get consistent results.

Then, please post to this thread with the following:

Card brand/model
Capacity
"Class" rating
Write speed (MB/s)
Read speed (MB/s)

Although it's not made obvious, the author has updated this app so that on Galaxy S phones it appends sd/ to the test path in order to test the external card (if present).

Results will be consolidated onto CapFAQ.com

I tested two cards. My 8GB is in use, full of data, and I just unwrapped my 16GB. Used the default buffer of 1MB. After seeing the results, I'm a bit concerned about the read speeds. Looks like more people are getting 13+ even with Class 4 cards, where I'm maxing out at 13 with the Class 10 and not even getting close with the Class 4.

SanDisk

Class 2
Write 3-4-4-4
Read 10-11-11-10

Just arrived yesterday, loaded it with 30 GB of ghost PC images and then loaded a bunch of other files, tested read and write of those files, everything worked as expected.

Loaded it into my phone and formatted... 31.20 GB

$59.99.

Where did you get it so cheap?

Ebay, Seller from New York I trusted from previous transaction, he must have been feeling out the market because he has since pulled the 'buy it now' auction, here is one of his completed listings TinyURL.com - shorten that long URL into a tiny URL he also threw in a USB adapter along with the SD card reader. If he still had them available I would recommend it to my mom if that means anything to you. As I am sure you know, there are lots of fakes out there, but that doesn't mean they all are. I have been researching for a while hoping to find the promised Samsung Class6 MicroSd card but I just could wait anymore. Didn't want to buy 16 when for just a bit more I could get 32...

On a completely different note and something you might want to consider in your benchmarks, I upgraded to Cog 2.2 B7 last night using the "From Eclair 2.1" steps found here TinyURL.com - shorten that long URL into a tiny URL and here are my numbers...

Write 6-7-7-7
Read 13-14-13-12

I was quite pleasantly surprised as this is now reporting class 6 speed, I even bumped the buffer up to 5MB and still got the same results.

I upgraded from 2.1 which had Unleash the beast v0.2 and RyanOCLF. Backed up my apps to my new card with TiBU, restore went perfectly.

Patriot 16gb Class 6
29.99 at Frys with SD adapter

7/15, 7/15, 7/15

I have a fistfull of movies on it and they playback very smoothly. Media scanning time isnt too shabby either, considering I have about 10 gigs of music on the internal and 12 gigs of movies on the external. Price for phone: 149.99, price for card $30. total, less than 200 for a 32gb phone. Price of 32gb Ip4 $300. Cant complain about that at least!
