This weekend I picked up a PNY 2GB MicroSD card from CompUSA B&M for $19.99. No sure how long the sale is. Mine is an SD-C02G JAPAN. This thing is smoking fast. Here are my HD Tach results ran from my silver R4DS USB adapter: Random access: 1.0ms Average read: 18.7 MB/s I've ran it several times and also ran ATTO with the same > 18 MB/s read. I've played C-POR for about 5 hours without any issues. Portals have not been an issue. I'll post back if it ever locks up on me.
