Performance in PCMark
PCMark 2005 has the same tests as the 2004 version (not only in names, but also in results as we have seen a lot of times), so we only use one test from PCMark 2004 which is not available in the 2005 version. It is called File Copying and measures the speed of copying some set of files. The other tests are:
- Windows XP Startup is the typical disk subsystem load at system startup;
- Application Loading is the disk activity at sequential starting-up and closing of six popular applications;
- General Usage reflects the disk activity in a number of popular applications;
- File Write is about the speed of writing files; and
- Virus Scan benchmarks the disk’s performance at scanning the system for viruses.
The final result is the average of ten runs of each test.
We’ve got the same standings are in the copying subtest of FC-Test.
We see the same standings in the Windows XP startup test. Take note that the 160GB X25-M is somewhat better than its 80GB mate in quite a lot of tests. This must be due to the updated firmware. The SSDs are also much better than the HDD. They are five times as fast as the latter! In our HDD tests different models do not differ more than twofold.
Oddly enough, the X25-M with older firmware goes ahead and pushes the X25-E back to second place.
The standings change again in the General Usage test. The X25-E is on top, followed by the 80GB X25-M whereas the 160GB X25-M sinks to last place, giving way to the Corsair.
This scanning for viruses test is highly sensitive to caching mechanisms and SSDs are still better than the WD Caviar Black. And if you look up the results of the best HDDs in this test, you will see that the worst SSD is no worse than them! Interestingly, it is the 160GB Intel X25-M that is the worst SSD in this test: its series mate with older firmware passes this test faster.
Here is one more file writing test. And there are no surprises: the SLC-based Intel X25-E and the Corsair are ahead, delivering two times more speed than the others. The slower SSDs are as good as the HDD, though.
The Intel X25-E is expectedly first in terms of overall score. The X25-M (the 80GB model with older firmware) and the Corsair share second place. The SSDs are superior to the HDD: the worst SSD scores three times as many points as the Western Digital Caviar Black.
