'Light Defrag' for SSD

post #1 of 2
Thread Starter 
---This is not a 'CAN I DEFRAG MY SSD' thread---

Getting that out of the way, are there any utilities that can move around your existing data on flash? I was thinking if you are in a high utilization situation (>90%) and writing a lot of data there would be a specific quantity of cells that experience a much greater write cycle than the others which are simply holding onto data at this point.

Or is the wear leveling implementation smart enough to move already existing data around (although that would incur a 'double write' scenario...)?

Thanks.

It depends on the controller.

3rd party software have no idea how a SSD controller works internally so they will all fail to be useful.

After writing, SSD do additional steps to organized data. This is quantified by the write amplification value.
