Hi all
I recently purcased a Sandisk Extreme Pro 280MB/s SD Card from a reputable Sandisk Reseller & got the following results using H2testw v1.4:
Warning: Only 60317 of 60318 MByte tested.
Test finished without errors.
Writing speed: 34.1 MByte/s
Reading speed: 35.9 MByte/s
Am I getting my MB/s & MByte/s symbols mixed up?
The reason I tested is because I used it in my BMPCC & got drop frames.
Thanks
Pete
The problem may be that it’s a USH-II card. The BMPCC only has a UHS-I reader, and perhaps whatever device you’re using to test the card is the same in that respect. This can cause dropped frames and speed issues, even when the card appears as it should to the device. I discovered this after buying a Lexar card that was UHS-II. You need to check Blackmagic’s list of approved cards, here: https://www.blackmagicdesign.com/support/faq/43083
