My ssd is much more slower than a hdd!!!

[gannicus]

I would NOT suggest having any kind of defrag software on an SSD.

With a properly installed SSD the bottleneck is with the I/O channel and the drive memory itself, not with the repeated seeks and SATA chip-level command set.

All SSD's can handle only a select number of writes. Even with wear balancing, a repeated series of endless writes will unnecessarily wear out your drive.

Google the topic, and you'll see maybe 100 reasons why.

Thanks for your suggestion.

By the why, I finally get a Crucial M4 ssd, it's perfect. the Verbatim ssd I had was just horrible
