otzer Hachochma can be installed on the computer without the hard drive being connected?
Yes, although it will not run without their security flash drive plugged in. However, performance for search is on a different level of fast.
Yes, if you have it install an internal ssd with a large enough storage capacity. Last I checked it was 2T but it goes up every time they update.
They just cleared 2TB on the last version, so you would need 4TB.
I thought that it can not be copied off the original drive, or they install it?
Don't know exactly how it is done. I personally did not do it as it was very expensive from what I heard.
The install process must be done through Otzar Hachochma. They charge a fee - IIRC, it was 170 shekel in EY. I'm sure you can ask them and they will tell you how much it will cost you. The biggest cost is that of the drive itself, currently around $200 (4TB).
