Terra should be Tera and doesn't only relate to bytes. Also, I saw no overlaps between groups.

Agree with Tom. Nice grid but extremely easy. It needs herrings and corssovers. I also agree with Tom that Peta, Tera, Mega and Giga are all SI unit prefixes donating scale in powers of ten. They can be applied to practically any unit, examples that commonly use them are Bytes, Bits, FLOPs and Hertz.

Fun, but very easy.

I would personally have expected 'Normandy' to be a key word on the relevant grouping ^^;

Beyond that, concurring with the SI Units point.

Thanks for the grid!

As others have mentioned, the peta/tera/etc. line applies to essentially any unit of measurement though, not just bytes.

Quite nifty, but it's terabyte, as already pointed out below. That's important, because terra has completely different connotations

Same as below comments.

I would have scored 10/10 if it hadn't been so specific to bytes as they are the names of any powers of the as pointed out below.

Should be re-graded as very easy.
