With this I use a Panasonic 512 MB "high speed" SD Card. Reading speed seems ok, iostat displays about 2,8 Mbyte/s reading transfer rate: tty ad0 da2 cpu tin tout KB/t xfrs MB KB/t xfrs MB us ni sy in id 128 101 36.00 2 0.07 8.00 363 2.84 7 0 4 5 84 168 191 17.70 33 0.57 7.99 361 2.82 9 0 3 5 83 360 115 0.00 0 0.00 7.99 359 2.80 10 0 6 4 80 464 194 64.00 1 0.06 8.00 358 2.80 9 0 5 6 80 112 94 0.00 0 0.00 7.99 362 2.82 9 0 4 4 84 112 215 8.38 21 0.17 7.99 360 2.81 9 0 3 3 84 But writing speed seems slow to me, I measure about 56 to 64 kbyte/s transfer rate only: tty ad0 da2 cpu tin tout KB/t xfrs MB KB/t xfrs MB us ni sy in id 2 110 16.00 1 0.02 8.00 7 0.05 19 0 4 2 75 9 209 16.00 1 0.02 8.00 7 0.05 17 0 2 1 80 8 94 8.00 1 0.01 8.00 7 0.05 19 0 2 1 78 12 110 40.00 2 0.08 8.00 8 0.06 28 0 2 2 68 10 113 0.00 0 0.00 8.00 7 0.05 16 0 2 2 81 11 113 16.00 5 0.08 8.00 7 0.05 17 0 5 0 78 Is that ok?
