Verifying Yet Another Sony 64 GB MicroSD Card

The replacement for the second failed Sony SR-64UY MicroSD card arrived:

Sony SR-64UX 64 GB MicroSDXC card

Sony SR-64UX 64 GB MicroSDXC card

The previous cards were made in Korea, but this one came from Taiwan with a different serial number format:

Sony SR-64UX 64 GB MicroSDXC card – back

The tiny letters on the front identify it as an SR-64UX, but I haven’t been able to find any definitive Sony source describing the various cards; their catalog page listing cards for digital still cameras may be as good as it gets. This one seems to have a higher read speed, for whatever little good that may do.

It stored and regurgitated the usual deluge of video files with no problem, which is only to be expected. This time around, I checked the MD5 sums, rather than unleashing diff on the huge files:

cd /media/ed/9C33-6BBD/
for f in * ; do find /mnt/video/ -name $f | xargs md5sum $f ; done
11e31c9ba3befbef6dd3630bb68064d6 MAH00539.MP4
11e31c9ba3befbef6dd3630bb68064d6 /mnt/video/2015-07-05/MAH00539.MP4
... snippage ...

It now sits in the fancy plastic display case that the HDR-AS30V camera came in until the previous replacement card fails.
