The TSM storage engine only reads the requested fields from disk, so there shouldn't be any significant read penalty for having that many fields per point. That would mean each point is a minimum of ~350KB in uncompressed line protocol. That's going to take a lot of wireline space to write each point, since there's currently no compression available for the write path.
How many points per second do you anticipate recording? If it's any more than 20 I suspect your tests will be challenging. Your use case is interesting, though. Are you storing telemetry?
