PC Pitstop

One or more partitions are using the NTFS file system. Although this file system offers many good features such as encryption, security, and improved reliability, it is often slower than the FAT32 file system. However, we do not advise switching back to FAT32 just to increase disk performance scores.

My results from test -

Cached speed -
NTFS - 100.03 MB/s
FAT32 - 75.49 MB/s

Uncached speed -
NTFS - 0.96 MB/s
FAT32 - 2.9 MB/s

So, it appears that the NTFS is faster when cached, but slower when uncached. :o
