After about 7.5 years (!) the 64 GB card in my Sony HDR-AS30V helmet camera breathed its last:
Over the course of several rides I noticed many video files ended prematurely or would not play. I gave up attempting to reformat the card in overwrite mode using the Official SD Card formatter after four hours, which says the wear leveler in the card has no spare capacity.
In round numbers, I ride 1700 miles a year at 12 mph, so the card recorded 1000 hours of 1920×1080 video at 60 frame/s, storing one 4.3 GB file every 22.75 minutes for a grand total of 12 TB of data.
Although that’s 188 times the capacity of the card, it rarely held more than an hour or two of data at any one time, because I copy the camera video files to a 3 TB USB hard drive after each ride. I don’t know how the exFAT file system interacts with the card’s wear leveling, but overall it’s much better than the non-high-endurance cards I’d been using way back when.
A new Sandisk 128 GB High Endurance card cost a third of what the 64 GB card did and, after setting the partition label to AS30V, it’s off to a good start:
That’s the street lamp pole installed on the replaced base at the corner of Rt 376 and Rombout House Lane, with the barrels gradually being pushed closer and closer to the pole by turning traffic on the newly paved lane.
That pole is not going to see the end of this year.
Update: The barrels vanished this morning:
Definitely the triumph of hope over experience.

A few bollards might be called for. They really should be more popular in this country.
I drove through the loading roadway of the local large Kroger affiliate. One fire hydrant had a moderate tilt away from the road, but the bollards were normal to the ground. I think I know what order they were installed. [grin]
