about hdd performance, here's what I have

$ sudo hdparm -t /dev/sda

/dev/sda:
 Timing buffered disk reads:  238 MB in  3.02 seconds =  78.86 MB/sec

$ sudo dd if=/dev/zero of=test bs=4M count=250
250+0 records in
250+0 records out
1048576000 bytes (1.0 GB) copied, 16.7282 s, 62.7 MB/s

$ sudo dd if=/dev/sda4 of=/dev/null bs=4M count=250
250+0 records in
250+0 records out
1048576000 bytes (1.0 GB) copied, 14.0408 s, 74.7 MB/s
