How to determine the erase block size of a flash drive?. Many says 128Kb is the default erase block size of NAND flash drives and aligning it with 128Kb reduces write cycles thereby increasing performance and life of the drive. Is this true?
Please share some detailed information.

Vorhandene Partitionierung ab Werk der aktuellen Sticks lässt auf 128kb Erasure Blocks schließen?

Model: SMI USB DISK (scsi)
Disk /dev/sdi: 8053MB
Sector size (logical/physical): 512B/512B
Partition Table: msdos
Disk Flags:

Number Start End Size Type File system Flags
1 127kB 8053MB 8053MB primary fat32
