Clone HDD to SSD, is it a problem.

[Lady Fitzgerald]

...True. SSDs don't need to be defragged. It's the way they roll. It's a chip, actually about 6 or more memory chips on a board withen a piece of plastic or metal casing. That's all an SSD is...

Not quite. SSDs do become fragmented but the controller can handle it far better than HDDs. However, if they become fragmented enough (20% or more), they will need defragging. However, it takes a while for them to reach that point, if they ever even get there. I've had to defrag only one SSD (and I have 31 currently in use) and that was after over two years of operation 24/7 on a 128GB boot drive. Larger drives usually take far longer before they need defragging, again, if ever. You do have to chck the amount of fragmentation in Win 7 (and keep automatic defragging turned off), may once a year (or, if you are really paranoid, twice a year). Win 8.1 and (shudder) 10 will manage everything on their own.

Also, there is far more to SSDs than memory chips, aka NAND chips. There is the controller chip (sometimes more than one), DRAM cache chip (in better SSDs), and (again, in better SSDs) backup power batteries and capacitors.
