标题Speed up your USB flash drive or memory stick using NTFS

The title says it all really, and in my case I got over 4x speed up. So you might want to consider trying this yourself!
During my experimentations with making my SD memory card a bootable XP Installer, I discovered this thread which raised the fact that NTFS was much faster for the purpose of installing Windows XP.
Not finding any useful article on the subject, even worse finding long discussions without any facts. I simply decided to try it, since it was quicker to try it than to parse all the noise on Google. By the way isn’t it another defeat of information noise and search when it is quicker to try something by yourself than to try to find it on Google?
The experiment
I was amazed by the results, it did not only speed up the install from the memory card, but it also dramatically reduced the time necessary to copy Windows XP over my memory card by a factor of over 4x!
More and more puzzled, I decided to make the test will all the old memory cards and USB flash drives I have at home. And to my amazement, the speed up was replicable on all my tests!
FAT32 is great if you need compatibility with some devices not running windows (in my case my digital camera) but if you do not need to, try NTFS you might get more value for your money, on top of that NTFS will allow you to copy files larger than 4GB without the need for splitting.
As a side note I would be interested to make an estimate of the humankind time wasted because of FAT32, might be an interesting interview open brainstorming question.
Back to the topic my test suite was very simple and consisted of two tests, ran both with FAT32 and NTFS and comparing the results with the raw drive speed measured with ATTO Disk Benchmark. By the way I ignored FAT since I used drives of over 2GB, but it might be worth testing with your own drives, for a good compromise of compatibility/speed. Bottom line is realizing how FAT32 can be slow.
1. Copying a folder that I like to carry everywhere. 5123 Files, 308 Folders and 2.83GB. Biggest files around 300MB and smallest files of 1KB.
2. Copying a large file of 4GB
On average with my memory cards and USB drives FAT32 results were abysmal with less than 1MB/s, whereas NTFS was still not great but managed around 5MB/s. Both are still very far from the maximum write rates obtained by ATTO as shown in the graph below.
Format your drive or memory card to NTFS the short way
1. Get and run HPUSBFW.exe from PC World or google for it
2. Select your drive, select NTFS and click Start
