Continuous logging with Data Logger Shield

[tim80bwi]

I am working on a project which involves sampling multiple air pressure readings and doing some calculation to produce altitude and velocity outputs. This works fine, but I would now like to record and timestamp these outputs somehow. I've been looking at the Adafruit Data Logger shield. This seems ideal for my needs, but I have read conflicting reports that I may have problems with continuous logging since all the read/write heavy-lifting is handled by my Arduino, not a dedicated controller on the shield. How much truth is there to this?

I'm looking to record three 16-bit values in a CSV-style format with a target sampling time of 50ms. Is this going to be feasible?

Many thanks!

Sampling 3 points at 20Hz is well within the capabilities of the logger shield.
