|A-Data Super 1GB ||  || Taiwan|| 1000|| 10.3|| || 1.6|| || Purchased at Meritline. SanDisk Imagemate 12 in 1 (a good reader) Ran the long test twice. Tested at near full capacity. Castlevania DoS intro plays fine. Tried PoR, it freezes when I spam start at Wind&lt;br /&gt;
|-&lt;br /&gt;
|A-Data Super 2GB || || Taiwan|| 2000|| 9.2|| || 1.9|| [[DeathMonk]]|| Using a PNY (I think) multi-reader. This card freezes in PoR when spamming wind (or whatever his name is), spamming that shop guy and spamming the warp.&lt;br /&gt;
|-&lt;br /&gt;
| Corsair MicroSD 1GB || MicroSD ||  || 1000 || 10.4 || 10.5 || 0.7 || [[Tokas]] || Purchased from Komplett.se SanDisk ImageMate 5 in 1 Reader.&lt;br /&gt;
|-&lt;br /&gt;
| Dane-Elec SD-C01G JAPAN 1GB|| || Japan|| 1000|| 2.6|| || 5.2|| [[bollocks]]|| My SD reader is dodgy at best. My phone identifies it as a Toshiba, so it&#039;s almost certainly the same as the other Toshiba/Kingston Japan cards.&lt;br /&gt;
|-&lt;br /&gt;
| Kingston 512MB (T512SAFAS 6401251)|| || Taiwan|| 512|| 6.3|| || 1.1|| [[shaunj66]]|| Purchased from a French website. A high speed USB 2.0 card reader.&lt;br /&gt;

Fresh FAT16 format with nothing but the OS and DoS &amp;amp; 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 &amp;quot;30&amp;quot; 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.&lt;br /&gt;
|-&lt;br /&gt;
| Kingston 1GB|| || Japan|| 1000|| 10.4|| || 0.7|| [[comapro]]|| SanDisk Imagemate 12 in 1. DoS intro - no lag. PoR - no crashes.&lt;br /&gt;

| Kingston SD-C02G || MicroSD || Japan|| || 19.2|| || 0.9|| [[jacare999]]|| FAT32 formatted card, tested with SanDisk Extreme reader.&lt;br /&gt;

=== Microdia 1GB XtraPlus (MSDC-1GB-30D2)(E247TN01G-NOBB0638) ===&lt;br /&gt;
* Reported by [[Sebokie]]&lt;br /&gt;

* Average Read: 9.3MB/s&lt;br /&gt;
* Burst Speed: 9.5MB/s&lt;br /&gt;

&lt;br /&gt;
=== PNY 1GB P-SDU1G-RF3 ===&lt;br /&gt;
* Reported by [[DeathMonk]]&lt;br /&gt;
* Made in: Japan&lt;br /&gt;
* Random Access: 1.2ms&lt;br /&gt;
* Read: 9.4MB/s&lt;br /&gt;
* 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.&lt;br /&gt;
&lt;br /&gt;
=== PQI 1GB ===&lt;br /&gt;
* Reported by [[magikalfly]]&lt;br /&gt;
* Made in Taiwan&lt;br /&gt;
* Random access 2.3ms&lt;br /&gt;
* Average read 6.4 MB/s&lt;br /&gt;
* 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&#039;t tested POR. Edit: POR crashes... :(&lt;br /&gt;
&lt;br /&gt;
=== Ridata 1GB ===&lt;br /&gt;
* Reported by [[magikalfly]]&lt;br /&gt;
* Made in Taiwan (I think)&lt;br /&gt;
* Random access: 3.2ms&lt;br /&gt;
* Average read: 6.4MB/s&lt;br /&gt;
* 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&#039;t as I had hoped. It also crashes on PoR.&lt;br /&gt;
&lt;br /&gt;
=== Sandisk 512MB ===&lt;br /&gt;
* Reported by [[jelbo]]&lt;br /&gt;
* Made in China&lt;br /&gt;
* Average read: 10,6MB/s&lt;br /&gt;
* Random access: 1.3ms&lt;br /&gt;
&lt;br /&gt;
* Reported by [[magikalfly]]&lt;br /&gt;
* Made in Taiwan&lt;br /&gt;
* Random access 2.6ms&lt;br /&gt;
* Average read 7.4 MB/s&lt;br /&gt;
* Notes: Purchased from ebay. Tested with USB2.0 flash reader. It&#039;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.&lt;br /&gt;
&lt;br /&gt;
* Reported by [[zatelli]]&lt;br /&gt;
* Random access 1.7 ms&lt;br /&gt;
* Average read 9.3 MB/s&lt;br /&gt;
* Burst speed: 9.5 MB/s&lt;br /&gt;
* 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.&lt;br /&gt;
&lt;br /&gt;
=== Sandisk 1GB ===&lt;br /&gt;
* Reported by [[SpaceJump]]&lt;br /&gt;
* Made in Taiwan&lt;br /&gt;
* Random Access: 1.3ms&lt;br /&gt;
* Average read: 5.2MB/s&lt;br /&gt;
* Notes: Crashes rarely on PoR.&lt;br /&gt;
&lt;br /&gt;
=== SanDisk 2GB ===&lt;br /&gt;
* Reported by [[id242]]&lt;br /&gt;
* Made in Taiwan&lt;br /&gt;
* Random access 2.4ms&lt;br /&gt;
* Average read 4.2MB/s&lt;br /&gt;
* SC(ONE) Score = 5&lt;br /&gt;
* Notes: RETAIL, purchased from Verizon the day they were released. Fresh FAT16 format with nothing but the OS and DoS &amp;amp; PoR copied for my testing. I&#039;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 &amp;quot;5&amp;quot; (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.&lt;br /&gt;
&lt;br /&gt;
=== Sandisk 1GB Ultra II ===&lt;br /&gt;
* Reported by [[cornaljoe]]&lt;br /&gt;
* Made in Taiwan&lt;br /&gt;
* Random Access: 0.8ms&lt;br /&gt;
* Average Read: 10.8 MB/s&lt;br /&gt;
* Notes: Purchased from Amazon.com. Sandisk Imagemate 12-in-1&lt;br /&gt;
&lt;br /&gt;
* Reported by [[jelbo]]&lt;br /&gt;
* Made in Taiwan&lt;br /&gt;
* Average read: 10,6MB/s&lt;br /&gt;
* Random access: 0.9ms&lt;br /&gt;
* Notes: Tiny PNY USB2.0 MicroSD reader. FAT16, default cluster size, filled with 967MB data.&lt;br /&gt;
&lt;br /&gt;
* Reported by [[shaunj66]]&lt;br /&gt;
* Made in Taiwan&lt;br /&gt;
* Random access 1.0ms&lt;br /&gt;
* Average read 6.7MB/s&lt;br /&gt;
* Notes: Purchased from MobyMemory.com A high speed USB 2.0 card reader.&lt;br /&gt;
&lt;br /&gt;
* Reported by [[Tokas]]&lt;br /&gt;
* Made in Taiwan&lt;br /&gt;
* Random access 0.9ms&lt;br /&gt;
* Average read 10.7MB/s&lt;br /&gt;
* Burst speed 10.8MB/s&lt;br /&gt;
* Notes: Purchased from a local Swedish store. (Kjell &amp;amp; co) SanDisk ImageMate 5 in 1 Reader.&lt;br /&gt;
&lt;br /&gt;
=== Toshiba SDC-01G-T 1GB ===&lt;br /&gt;
* Reported by [[111111111]]&lt;br /&gt;
* Made in Japan&lt;br /&gt;
* Random Access : 1.7ms&lt;br /&gt;
* Average Read : 4.3MB/s.&lt;br /&gt;
* Notes: Tested with the R4 bundled USB MicroSD reader (different to all the pics I&#039;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&#039;t have any other adapter to test with. I&#039;ve had absolutely no problems with this card - tested 50ish games so far (including both castlevania games) - except for the &#039;none realtime&#039; in tony hawk downhill jam.&lt;br /&gt;
&lt;br /&gt;
=== Toshiba SD-C01GR2W (SD-C01G) 1GB ===&lt;br /&gt;
* Reported by [[DeathMonk]]&lt;br /&gt;
* Made in Japan&lt;br /&gt;
* Random Access: 1.2ms&lt;br /&gt;
* Read: 9.4MB/s&lt;br /&gt;
* Notes: PNY multi reader. Castlevania: Works like a charm. Same results as my PNY SD-C01G. It&#039;s pretty safe to say that if you get a SD-C01G you&#039;re good... No matter what manufacturer.&lt;br /&gt;
&lt;br /&gt;
=== Toshiba SDC-01G-T 1GB ===&lt;br /&gt;

* Average read 9.4 MB/s&lt;br /&gt;
* Burst speed: 9.5 MB/s&lt;br /&gt;
* Notes: Purchased from totaldiscountstores.com (which is an ebay store) Tested with a Sandisk mobilemate SD+ USB2.0 flash reader. My card was almost full when tested. Haven&#039;t had a single issue with any game so far, it even whips Castlevania POR. BTW, I&#039;ve Run the quick benchmark test 3 times &amp;amp; the results I&#039;ve posted are the worst I&#039;ve got.&lt;br /&gt;
&lt;br /&gt;
