I didn't know "terabytes (TB)" was a unit of memory bandwidth...

It’s equivalent to about thirteen football fields per arn if that helps.
Bit of an embarrassing typo, they do later qualify it as 3.7TB/s
Most of the time bandwidth is expressed in giga/gibi/tera/tebi bits per second so this is also confusing to me
Only for networking, not for anything measured inside a node. Disk bandwidth, cache bandwidth, and memory bandwidth is nearly always measured in bytes/sec (bandwidth), or NS/cache line or similar (which is mix of bandwidth and latency).
About as relevant a measure of speed as parsecs
