创见4G SDHC Class 6(MLC) + 飚王SSK USB2.0读卡器(GL828芯片)

数据

川宇SDHC 150x读卡器
金士顿SD普速卡

Transcend创见SDHC 4G Class6
读卡器：
1，黑色ATP ProMax ；
2，川宇SDHC 150X为了对比，拿大名鼎鼎的Sandisk Extreme III SD 2G一起测。
看来，10元钱的川宇SDHC 150X读卡器真是物有所值，确实达到sandisk标称的写19/读20。比百元的ATP ProMax读卡器强！！

ATP双枪将的成绩

好像还不如我用川宇的SD/SDHC 150x读卡器测试的成绩

HD tune V2.54好像识别不出来川宇的读卡器。
找了个HD tach测了一下。
由于我的单反又拿去修了，现在没法测试。

必恩威(PNY) 4G SDHC高速存储卡（CLASS4）
花了199买的，挺便宜的。

顾老说得对，Olympus E3和SONY A700支持UDMA确实比较充分。不知道Canon的1DM3、1DsM3和Nikon的D3对UDMA技术的支持度怎样？

哈哈，顾老玩的都是顶级货啊

PS，刚才粗略在dpreview查了一下，Canon的1DM3、1DsM3和Nikon的D300、D3都支持UDMA技术。

刚买了一块Sandisk extreme IV 4G CF卡和一个配套的Sandisk extreme FireWire Reader(1394火线口),测试下来确实相当了得:

东芝2G Class6 +鹰泰读卡器=165+15
我朋友用另外一个读卡器速度达到写10M/s,读取20M/s,看了这个读卡器的速度还没能发挥卡的性能.

第一次用这个测试，不会用。重测：

怎么会有这样的速度，哪里做得不对？
sandiskIII 4G CF
eagletec  28-in-1

换个读卡器试试。
