Performance in FC-Test

The last benchmark we are going to use in this test session is X-bit’s own FC-Test. We tested our hard drives in a usual way with the help of five patterns differing from one another by the number of files involved and their size. Overall we performed four types of operations. First we created files in the tested array on the first 32GB section (Create). Then we read the entire set of files from the drive (Read). Then we copied this set of files within the same section (Copy Near). And in conclusion we copied the whole set of files from the first 32GB section into the second section of the same size (Copy Far).

Let’s start with FAT32 file system.

The first diagram shows how quickly the files were created when the HDDs were formatted for FAT32 file system. We can see that WD2500SD is far ahead of the rival here in all five patterns and in both modes tested. The performance difference is especially noticeable when we compare the arrays’ performance.

File reading results into the same flawless victory of the WD2500SD over WD2500PD. Just as in the previous case the gap between the two testing participants grows bigger when we have arrays working.

Copying files within the same section makes WD2500SD look even better. It appears almost twice as fast as the opponent in most patterns. This is actually true for both testing modes.

The last diagram shows how quickly the drives allow copying the file sets from one section to another. Again WD2500SD is ahead in all patterns.
