SC(ONE) plays DoS intro perfectly and not a single crash on PoR either. The SC(ONE) gives it a score of "30" and I can run most games at 4x without any problems. SC.lite plays the DoS intro perfectly and not a single crash on PoR.

• Random access: 3.2ms
• Average read: 6.4MB/s
• Notes: Purchased from meritline.com. Tested with USB 2.0 flash reader. Tried test with other readers as well and same result. I got it because it was suppose to be the fastest microsd card out there but speeds aren't as I had hoped. It also crashes on PoR.

SanDisk 2GB

• Reported by id242
• Made in Taiwan
• Random access 2.4ms
• Average read 4.2MB/s
• SC(ONE) Score = 5
• Notes: RETAIL, purchased from Verizon the day they were released. Fresh FAT16 format with nothing but the OS and DoS & PoR copied for my testing. I've found that my SanDisk 2gb MicroSD is absolutely horrible for transferring files to and from. On the SC(ONE) the DoS intro is unbearably choppy and the DS(ONE) gives it a maximum score of "5" (which is 2x). If i set the speed for anything faster than 2x in the SC(ONE) settings, many games freeze up during/or halfway through booting. The card works great on the SC.Lite though the DoS intro, about half-way into it, does not run smooth (but more smoothly than on the SCSD) and PoR gets random freezes.

Toshiba SDC-01G-T 1GB

• Reported by 111111111
• Made in Japan
• Random Access : 1.7ms
• Average Read : 4.3MB/s.
• Notes: Tested with the R4 bundled USB MicroSD reader (different to all the pics I've seen on the net, a small translucent black one - seems quite sturdy/solid, if a little slow) which is obviously the speed bottleneck. I don't have any other adapter to test with. I've had absolutely no problems with this card - tested 50ish games so far (including both castlevania games) - except for the 'none realtime' in tony hawk downhill jam.
