WD Passport benchmarks
Two months ago I bought a Western Digital My Passport Studio 500GB with USB 2.0/Firewire 800/400. It has a 5400rpm hard disk. It is self-powered what was the main reason I bought. First, I was looking for an external hard disk that has inside a 7200rpm hard disk and is self-powered. I couldn’t find such thing. So I decided for this one. I am pleased with this model. It is quiet, except there are sometimes clickings, but that is that annoying. The second most important thing was the Firewire 800 port for my iMac.
And of course I made some benchmarks if you are interested in for some numbers.
Created a 1GB big file named benchmark_1G in Terminal:
dd if=/dev/zero of=benchmark_1G bs=1m count=1024
Copied the file benchmark_1G from iMac’s HDD to WD Passport and vice versa (HFS+ partition):
time cp benchmark_1G /Volumes/My\ Passport/ (for writing)
time cp benchmark_1G /Users/$home_folder (for reading)
Firewire 800 results:
Writing
real 0m19.622s
user 0m0.003s
sys 0m1.281s
That is 52,24 MB/s. That is not bad at all because the WD Passport has a 5400rpm hard disk.
Reading
real 0m20.525s
user 0m0.003s
sys 0m1.514s
That is 49,95 MB/s.
USB 2.0 results:
Writing
real 0m34.243s

29,91 MB/s.
Reading
