HD Tune Performance
While not entirely indicative of real world performance, HD Tune does give us a glimpse into a hard drive's inner workings. Its transfer rate benchmark measures speed across the entire disk, giving us an idea of how fast it is over its entire span.
HD Tune measured an average and maximum read speed of ~104 and ~138 MB/s respectively for the 5K3000. The Samsung EcoGreen F4 and Caviar Green WD20EARS sport three 667GB platters as well but the higher spindle speed of the Deskstar 5K3000 and Barracuda Green likely give them the advantage in this test.
"Green" drives usually have poor access times and the 5K3000 is no exception at 19.5 ms. This will undoubtedly slow down the drive's loading times and hamper other tests which require rapid access of large numbers of files.
Real World Performance
A Windows 7 image loaded with our test suite was cloned to a 50GB partition
at the beginning of each drive and our entire
test suite was run start to finish 3 times with a reboot and defragmentation
in between runs except for the Momentus
XT (defragmentation resets optimizations made to the XT's flash memory).
Average times were collected for comparison.
Loading times are one area where sub 7200 RPM drives consistently struggle so it's encouraging to see the 5K3000 buck this trend by more or less tying with the Deskstar 7K1000.C. Boot time in particular was much faster than the popular WD20EARS and EcoGreen F4.
In application performance the 5K3000 acquitted itself nicely, keeping company with the Barracuda XT and Deskstar 7K1000.C.
