While I agree with all that goes before, in general terms, and particularly with regard to Calibre, it is worth reading the attachment about defraggers and SSDs. Essentially, it says that not only is it unnecessary to defrag an SSD, it is actually harmful. O&O, the producers of the German defragger O&O Defrag, go on to advise that the defraggers supplied with WinXP and WinVista cannot detect SSDs, although the one supplied with Win7 can.
O&O Defrag, on the other hand not only detects SSDs, and avoids defragging them, it will run the beneficial TRIM function on them.
Of course, O&O Defrag is not a free product.
