Dane-Elec SD-C01G JAPAN 1GB [bollocks] Made in Japan Random access: 5.2ms Average read: 2.6 MB/s Notes: My SD reader is dodgy at best. My phone identifies it as a Toshiba, so it's almost certainly the same as the other Toshiba/Kingston Japan cards.

Fresh FAT16 format with nothing but the OS and DoS & PoR copied for my testing. 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.

Kingston 1GB [SynGamer] "Generic- SD/MMC 1.00" Made in Taiwan Random Access: 1.6ms Average Read: 10.0 MB/s Notes: I bought mine at Buy.com and it is labeled as a Kingston 1 GB microSD. I used the Bonzai USB Flash Drive by SimpleTech, along with the included Kingston microSD Adapter, to test my microSD card.The card has the following on the back of it: "SDC/1GB 30785-001-A00LF Taiwan" Anyway, so far every game i have tried (except Worms: Open Warfare) has worked perfectly. MP3's included. The game i believe was just a bad file (in the process of finding a replacement to test)

PNY 1GB P-SDU1G-RF3 [DeathMonk] Made in: Japan Random Access: 1.2ms Read: 9.4MB/s Notes: Same 9in1 reader I tested my A-DATA Super 2GB with. Castlevania PoR: No problems whatsoever... Even trying to get it to lock up. Seems to play the opening video at a higher framerate than my a-data--could be just me though.
PQI 1GB [magikalfly] Made in Taiwan Random access 2.3ms Average read 6.4 MB/s Notes: Purchased from Meritline.com Tested with USB 2.0 flash reader. I tested with the card almost full. About 900 megs on it. No problematic game so far. Intro to Castlevania DOS plays pretty choppy. No problems in-game though. Haven't tested POR. Edit: POR crashes... frown.gif
Ridata 1GB [magikalfly] Made in Taiwan (I think) 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 512MB [jelbo] Made in China Average read: 10,6MB/s Random access: 1.3ms
Sandisk 512MB [magikalfly] Made in Taiwan Random access 2.6ms Average read 7.4 MB/s Notes: Purchased from ebay. Tested with USB2.0 flash reader. It's an old card I got to use with my phone. Tested with 440 megs on it. I only use this with my phone so no games tested.
Sandisk 512MB [zatelli] Random access 1.7 ms Average read 9.3 MB/s Burst speed: 9.5 MB/s Notes: Shipped with my cellphone. This card, which has some issues with problematic games (white screen which lasts a couple of seconds in most games (including nanostray, New Super Mario Bros, Castlevania POR) has benchmark stats specifications similar to those of my recently purchased Toshiba (J) 1GB uSD.
Sandisk 1GB [SpaceJump] Made in Taiwan Random Access: 1.3ms Average read: 5.2MB/s Notes: Crashes rarely on PoR.
SanDisk 2GB [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  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.
Toshiba SD-C01GR2W (SD-C01G) 1GB [DeathMonk] Made in Japan Random Access: 1.2ms Read: 9.4MB/s Notes: PNY multi reader. Castlevania: Works like a charm. Same results as my PNY SD-C01G. It's pretty safe to say that if you get a SD-C01G you're good... No matter what manufacturer.
