partitioning - Will 4096 bytes alignment benefit on SSD with 512 bytes sector size?

My SSD physical sector size is 512 bytes. Will 4096 byte alignment benefit in IO operations? Currently the 1st partition (Recovery) has starting offset at 32 256 bytes according to msinfo32. The second partition (system) has the offset at 115 153 920 bytes.


Some more data from fsutil output:


Bytes Per Sector : 512


Bytes Per Physical Sector : 512


Bytes Per Cluster : 4096


Bytes Per FileRecord Segment : 1024
