disk errors on heavy write I/O

Wed Feb 13 17:41:12 UTC 2013

when doing lots of writes (large file) after few tens of gigabytes i've 
got as below.

smartctl -t long (full surface test) reports no errors

my disk is
ada0 at ahcich0 bus 0 scbus0 target 0 lun 0
ada0: <SAMSUNG HD154UI 1AG01118> ATA-7 SATA 2.x device
ada0: 300.000MB/s transfers (SATA 2.x, UDMA6, PIO 8192bytes)
ada0: Command Queueing enabled
ada0: 1430799MB (2930277168 512 byte sectors: 16H 63S/T 16383C)

i have the same drive model at other place, and got into the same 
situation once.

any ideas what it is. i cannot find any firmware update.
