Usually, we say, "This library has twice as many books as that one." and "The new usb has twice the storage capacity of the old one."
Then is it possible to say "The number of the books in this library is twice of that one"
or "The storage capacity of the new usb disc is twice as large as the old one"?

The "usb disc" sentence seems fine to me, but not "The number of the books in this library is twice of that one".
I would say:
"The number of the books in this library is twice the number in that one".
"The number of the books in this library is twice the amount in that one".
"The number of the books in this library is twice what's in that one".

The number of books in this library is twice that of the old one.
The storage capacity if this USB is twice that of my previous one.
Remember - correct capitalisation, punctuation and spacing make posts much easier to read.
Those sentences add further context that could be incorrect.
By saying 'old one' you are implying the one you're talking about is a new one, not just a different library.
The same as with the USB. By saying 'of my previous one' you are implying he already had one. He could be comparing two USBs in the store?

Fine.
The number of books in this library is twice that of/in that one.
The storage capacity of this USB drive is twice that of that one.
No matter how you start or end the sentence "twice that" is still correct.
Remember - correct capitalisation, punctuation and spacing make posts much easier to read.
"The number of books in this library is twice the number of that one."
This is a very poor sentence. It's unclear and unnatural.
Thank you all so much for the help. I'll take emsr2d2's suggestion and use "twice that of..."
I'm not a teacher, but I write for a living. Please don't ask me about 2nd conditionals, but I'm a safe bet for what reads well in (American) English.
