Now let’s check the controller performance in FAT32:

The speeds of the arrays in Business Disk Winmark and High-End Disk Winmark:

The arrays took the same places as in NTFS, but their absolute speeds have grown up. RAID10 outperformed the single drive – a nice surprise! A nasty exception is RAID1’s becoming the last.

Let’s compare these results to ones we have when disabling the lazy write algorithms of the hard disk drives:

When caching is disabled, all arrays suffer a performance hit.
