Anyone ever defrag their microSD card?

[germie]

I just did, it was a cluttered mess!

This was after of course.

I have defragged flash drives before but it's pointless, seeing as it's not a mechanical hard drive that has any access latency - as I understand, flash can access data at the same rate anywhere in memory since electrical impulses are instant. Hard drives of course have to go distances to grab data, hence the need to defrag them. This also needlessly eats up your limited number of read/write cycles of the flash memory.

I have seen very little benefit of running a defrag on a SSD (Flash or HDD).

I have run Defrag on my SD card, i didnt notice the diference after i've done it...

Yeah, solid state disks do not fragment like normal Hard Disks.

i defrag a jump drive once and it never worked again

Supposedly defragging SSDs actually do more harm than good. Since SSD's have no seek time it doesn't matter if the files are defragged, at least not noticeably. If you constantly move around and write/erase the bits on an SSD, it can wear out the bits and reduce the life of the SSD.

I also remember getting a warning from a Defrag program(dont remember the name)saying that defragmenting that unit(SD Card) could cause damage to it, so i didnt doit.

Most flash memory devices support a certain number of rewrites per sector before those sectors start to error. As defragging results in a large number of rewrites it can shorten the life of a device particularly if done repeatedly. As others have already pointed out there should be no decernable performance benefit from defragging flash devices.

LOL, I had the same thing happen to a one gig SD card.
