Performance in WinBench 99

We’ll use WinBench to record data-transfer graphs:

• Samsung 32GB SSD
• Samsung 64GB SSD
• Gigabyte i-RAM
• Fujitsu MBA3300RC
• Samsung SpinPoint F1, 1GB
• Hitachi 7K200, 200GB

The next diagram shows the data-transfer rate at the beginning and end of the partition:

There are a few interesting points here. First of all, the reduction of speed at the end of the 64GB SSD is merely an error of the test program: every cell has the same speed, of course. Second, you can see that the SSDs have a much higher read speed than in the IOMeter: Sequential Read test. You’ll see shortly how they perform under real-life conditions. And third, you can see where the SSDs and i-RAM differ from the HDDs clearly: they have the same speed through all of the drive’s capacity. As a result, the i-RAM will have a somewhat higher average speed than the Fujitsu MBA3300RC, and the SSDs will be no worse than the Hitachi 7K200.
