5 out of 5 eggsGreat so far

Pros: Fast, cheap

Cons: None

Other Thoughts: Haven't had any real-world use yet, new camera is still in the mail. So I can't speak to durability or longevity. It's not noted here, but PNY is producing these for HP.

I ran the benchmarks on it and they look good.

For ATTO Disk Benchmark, here are the peaks:

Write: 18.2 MB/s
Read: 22.6 MB/s

With h2testw, I get the following.

Write: 13.9 MB/s
Read: 20.1 MB/s
