Hi again,
Tested my cards with ATTO Benchmark. Lexar 4GB 300X & Silicon power 8GB 400X, normal USB 2.0 all-in-one card reader, Macbook Air 2011 edition.
result
Lexar read 22-24MB/s write 31MB/s
Silicon Power 18-20 MB/s write 31MB/s
Any idea, why both are far under standard, and Silicon power worse 400X, even behind leexar 300X? Is it my testing environment issue?
Anyone can advise?
Thank you.
