The Google study you linked says "25,000 to 70,000 errors per billion
device hours per Mbit".
Assuming bits, {25000 to 70000}/1e9 * 3016 1000 = 12 to 33.6 bit errors per month. Assuming bytes, it's 96 to 268 bit errors per month.
Apparently you've meant bytes, not bits. (I'm a pedant, but was also just unsure and interested in the numbers.)
FWIW, a comment I ran across that confirms toast0's view[1]: "It's a bimodal distribution - you either have many errors (due to a defect somewhere) or basically zero. If you're on the good side of the distribution, with only extremely rare errors, then you probably don't need ECC. But without ECC, you don't know whether you need ECC!"
