I have recently bought a 32GB Sandisk Cruzer Blade pendrive and as FAT32 file system limits file size to 4.5GB, I’ve formatted it to NTFS as I normally use the Windows environment and as to carry large file chunks more than 4.5GB per file at a time.
I’ve used the default allocation size, as I technically don’t know what this means. And also have tried with 16KB of allocation size. There was no change. Obviously I have got USB 2.0 ports and so I’m not expecting huge speed. While trying to copy a 5.6GB of file to my pendrive, the transfer starts at a speed of about 88MBps and gradually it gets down to the lowest of 1-2Mbps. After visiting some sites, I applied some tweaks:
Right clicked on the drive, select property, clicked on hardware, selected my drive, clicked on property, clicked on policy tab, and then checked the ‘Better performance’ option.
Well it did some improvement as earlier, during the remaining 3-4MB of the copy, the process was getting stopped and then took more 5-8 minutes to finish the copy process, this time after going through the above mentioned tweak, the transfer smoothly got finished off. I admit that my pendrive is the cheapest of its range but still I want to know if this is an obvious issue or not. I heard that this issue is resolved in Windows 8, is it true? And is there any resolution for Windows 7?
The transfer rate to my pendrive in NTFS gradually decreases from 88MBps to the lowest of 1MBps.
