Do you want to use 4K alignment for u disk?

4K alignment is a hard disk that conforms to the 4K sector definition format and writes data according to the rules for "4K sector". Generally speaking, the problem of 4k alignment has always been for hard disk products, especially after the emergence of solid-state hard disk, flash memory is more dependent on the best read and write mode, so the 4K sector alignment has become a particular concern of consumers. Then also is the flash drive, from the erase loss, it is similar to SSD hard disk, whether it also needs to use 4k alignment? Is there any need for alignment? I believe this is also a lot of consumer concerns, the following is a small series of detailed answers.

Under the Win7 system, use the system with the tool to partition the U disk, formatted after the partition we can choose whether to do "4K alignment", in fact, u disk and hard disk is not the same, from the U disk and hard drive differences look, u disk only single flash memory chip itself is not needed to align, The hard drive is because not 4K alignment will result in a data multiple chips across the write so performance will drop, so the U disk does not necessarily need 4k alignment.

From the standpoint of life, reduced life is only ancillary effects, 4k alignment will only affect a data at the same time to write a number of chips and affect the total average life, and for only a single chip USB disk, the problem does not need to worry about, accurate, all the multiple chip write flash devices need 4k alignment, but 99% U disk is just a single chip, alignment does not have much meaning.

So we can sum up, u disk does not have 4k alignment of the necessary, of course, if you want to align also does not matter, because the strict meaning of the U disk is impossible to completely 4k alignment, for this reason, U disk use does not use 4k alignment exists is not much impact.
