Can your laptop really sustain more than 25MB/sec of writes to its disk?

dd if=/dev/zero bs=1m count=8192 of=bigfile
8192+0 records in
8192+0 records out
8589934592 bytes transferred in 124.189 secs (69168240 bytes/sec)

this is just a normal 500G laptop disk, not quite 2 years old.

Yeah, I get easily 80MB/s scping files from/to my 2 years old laptop. With your dd test I get 50MB/s.
