What's the difference between 970 evo and 970 evo plus?

As another responded - only current specs, reported by the reputable test sites (I researched these and WD thoroughly across several testers - don't have site name this moment, but I bought it and I _never_ click buy until I am certain - anyway. Read speeds are equal, write speeds are 2500 MB/s for EVO and 3300 MB/s for EVO Plus. At this price it is a no-brainer. Incidentally - even the 970 EVO wiped the floor with WD Black in those same tests. Samsung 970 EVO/EVO Plus, 980 et al.. are the best SSDs you can get, especially for these great prices. Daayyum. I'd jump at this price if I hadn't already :-)

Do all variants (250gb and 1TB) have the same speed?

nope, check on detailed specs on Samsung website https://www.samsung.com/semiconductor/minisite/ssd/product/consumer/970evoplus/ 250GB 2,300 MB/s ; 500GB 3,200MB/s ; 1TB/2TB 3,300 MB/s

where is the 2tb drive?

Product comes with new higher density flash memory. Samsung should release 2TB version as soon as they maintain mass production of 512 bit density flash. Early predictions are that it should come in April.

Will the 500gb sdd clone my 1tb system partition with 200gb used, on my hdd, and is the process automated?

It is not clear if the source is 500GB or 1TB. For Clonezilla to work, the destination partition must be equal or larger than the source one. It seems your source is the 1TB partition. You will need to shrink the 1TB system partition to less than 500GB for Clonezilla to work. That said, Clonezilla is a wonderful program and does a "bare metal" backup of used space to be efficient in backup capacity.
