Pan test nr 1 Pan test nr 2 Nr 1 is on the EMMC Nr 2 is saved on the SD, which is smooth for about 30 secs or so, then skips a little every 30 seconds, assumingly speed is a limiter. My benchmarks over mass storage are as follow: EMMC: Unbuffered Write: 12/14.7/14.2 M/s (Min/Max/Avg) Unbuffered Read: 9/9.57/9.4 M/s (Min/Max/Avg) SD: Unbuffered Write: 8.2/8.25/8.22 M/s (Min/Max/Avg) Unbuffered Read: 8.12/8.25/8.20 M/s (Min/Max/Avg) Benchmark software is my own home brew, using Windows single-thread unbuffered read. I'd link you, but I'm having a little trouble with my provider page, it seems to be under maintenance.
