What is Disk Fragmentation on Windows and how does it optimize your hard disk?
In: 57
If you think fragmentation can’t occur, consider a programmer who sets out to fragment files with multiple threads, do you think his actions will be unsuccessful?
Fragger.exe does a good job of burning through the write cycles of ssd and setting up fragmentation.
If your 50gb of 20byte files are “randomly” smeared over a ssd the devices storage is fragmented meaning many more read cycles are needed to construct a stream of data to feed back to the OS as it’s not contiguous even if you have 10m IOPS you will see performance drop off and that’s the manifestation of fragmentation it slows down.
So ssd do suffer with fragmentation- but to a lesser degree.
A real world example is setting up a nas to torrent if you have a scratch disk fragmentation is quickly noticed on it.
Using a ssd will speed things up hugely but the ssd will wear out.
Using system memory, as the scratch area will speed things up even more and save the ssd.
