Since the data-transfer rates are the same in NTFS and FAT32, we only publish one diagram for both file systems:

Here are the data-transfer graphs for each of the arrays:

• Linear read graph for JBOD (1 HDD);
• Linear read graph for RAID0 (2 HDDs);
• Linear read graph for RAID1 (2 HDDs);
• Linear read graph for RAID0 (3 HDDs);
• Linear read graph for RAID0 (4 HDDs);
• Linear read graph for RAID10 (4 HDDs).

Conclusion

The Sil 3114 controller delivers a nice performance, but only with RAID0 arrays. Mirrored arrays don’t provide any speed bonuses – you should only use them to ensure the security of your data. You may remember from our reviews of dual-channel SATA controllers that the reference BIOS/driver pack from Silicon Image doesn’t have any optimizations for mirrored arrays, but focuses on increasing the speed of RAID0 arrays. As a result, the Sil 3114 can be recommended to people who need an inexpensive controller to give a speed boost to the disk subsystem of their computer.

Currently, you can download drivers for Windows 98 SE, Me, NT, 2000 and XP as well as for 64-bit Windows and Novell Netware from the manufacturer’s Web site (Windows 95 is not supported). If you are a Linux user, you can only try the beta version of the driver.
