Performance in WinBench 99

This benchmark allows evaluating the performance of the disk subsystem in desktop applications, in NTFS and FAT32 file systems.

NTFS comes first:

And here are the results of the two integral subtests, Business and High-End Disk Winmark:

The most astonishing of the results is the speed of the single drive with TCQ disabled: it seems like TCQ greatly impedes the controller in this mode. This may be due to the file system, but we had no TCQ-related problems in the Workstation pattern that works in NTFS, too.

The RAID0 arrays are expectedly the fastest among the other array types. The mirroring arrays (RAID1 and RAID10) took the last places.

Let’s now switch to FAT32:

Unlike in NTFS, the rankings vary depending on the subtest: if we sort the arrays by their speeds in Business Disk Winmark, they would line up in the same order as in NTFS. This once again proves that the bonus from TCQ comes irrespective of the file system.

And if we sort the drives by the speed in High-End Disk Winmark (as we did in the diagram above), the single drive without TCQ will be right after the single drive with enabled TCQ ?the rankings look quite logical in this case.
