05.27.2011 Benchmark 5X50MB Initial Test Results

87 out of 90 tests run.

3 tests unable to be completed due to hardware failure.

I started this test with 4 MicroSD to SD card adapters and one USB MicroSD card reader.

Right away the 2 PNY MicroSD to SD adapters did not work. One was years old, the other brand new with the PNY C10 card I got. I know the old one used to work.

Every memory card I have works in every other adapter. Those two won't read any card. I am confused, but proceed with the test anyway. Now testing with 2 MicroSD to SD adapters and one USB adapter.

The USB adapter quit on me right at the last 3 cards of the last test. I could not get it to read any cards, it just up and stopped working with no warning.

The 3 Sandisk cards have all 5 tests on each reader. The two PNY and one DaneElec card are missing the data from test 5 on the USB reader.

*Note: After this test I switched my "tag" for ach of the SanDisk C4 8G cards in this test.

For these results in this post only:

- SanDisk C4 8G (1) is actually listed in my hardware post as SanDisk C4 8G (2).

- SanDisk C4 8G (2) is actually listed in my hardware post as SanDisk C4 8G (1).

Sorry for any confusion this may cause.
