I just got my adata 4gb microSDHC card and it works great, super fat. It is a class 6 card(meaning certified to read/write at 6mb/s) several ppl care claiming speeds up to 10mb/s. class 6 is the fast out right now, and as far as i can tell adata is the only one making a class 6 card. i am using a sandisk sdhc usb card reader(compact, clean, and fast). I have used other adata products with much success as well. 1gb micro sd card(1 year) ddr2 desktop ram(several comps, tons of great reviews)

Newegg.com rocks.
