✍: FYIcenter.com
The best way to find out the maximum writing speed of your Seagate ST500DM002-1BD142 ATA HD is to run writing tests with a single large block of different block sizes:
sqlio -LS -kR -i1 -f1 -t1 -s30 -p0 ...
If we run SQLIO with above options and different block sizes, we should be able to find the maximum writing speed:
Throughput Throughput Latency Block Size MBs/sec IOs/sec ms ---------- ---------- ---------- ------- -b16 30.43 1947.49 0 -b64 55.27 884.34 0 -b256 86.51 346.05 2 -b1024 114.20 114.20 8 -b4096 95.54 23.88 41 -b16384 72.14 4.50 221 -b65536 91.94 1.43 695 -b262144 94.62 0.36 2704
As you can see, the maximum writing speed, 114.20 MBs/sec is reached with a block size of "-b1024", or 1 MB.
Comparing to the maximum reading speed of 216.56 MBs/sec, the maximum writing speed of 114.20 MBs/sec is about 2 times slower.
