So, I send an email to Riddler saying that we need to order two 100gb drives in order to replace the failed NAS drive.

He responds with an email saying he’s ordering them.

He then comes back to the production area later to tell me, ‘I ordered a 150gb drive.’

Of course, that won’t be enough space to copy all the data, which is why I explicitly said we need two 100gb drives (= 200gb, not 150gb).

In Riddler-world, 150 = 200.
