sorry people.. little changes in the speeds.
NTFS
Read: 25 to 28 MBPS (I get 25 MBPS, on friends laptop Sony Vaio - 28 MBPS, dont know why this difference.. but friends lappy got 28.3 MBPS throughout to be exact) I must say, this is an amazing pen drive..
and the usable capacity after formatting is 15.0 GB in NTFS, 15.1 GB in FAT32 file system.
