I have a new SSD Drive (128GB) and I was experiencing some poor performance.
I read in another older thread about it and I want to post here my findings.
Windows has a very good utility to check performance of Drives : Elevated Comand Prompt >
Winsat Disk -Drive X (X is Drive is letter you want to test)
There you get all testing results of Read/Write/Rand/Seq and other.
Most significant and important is the Latency : Maximum. There is a huge diference from NTFS and ExFAT (2500 vs. 500)
Also, the Sector size in ExFAT has a significant impact on this Latency. I was testing with 16K, 32K, 64K and 128K.
64K is Good but I thing 128K is a litle better.
