Yes, I am starting to hate solid state devices, I have had problems in
the last couple of years with two SD cards and a Kingston SSD drive.
I do not remember so much problems with HDD drives during my life 🙂 or
perhaps my memory is getting old as I am...
SSDs are not build for high write counts contrary to spindles. Reducing the
amount of write ops to the SSD (i.e. by larger RAM for filesystem caching,
using a more fitting filesystem and filesystem parameters) is crucial to
reach a longer lifetime. Doing a regular FSTRIM is important too to free
unused blocks (NetBSD seems a bit intransparent to me in this regard).
Beside this there are SD Cards with "crippeled" or buggy wear leveling /
electronic leading to corrupted cards when driven with more complex access /
SCSI commands. Most are sold for "tyoical" applications like saving photo or
video files in cameras or provide a mostly "read only" medium (i.e. jus hold
some firmware) - means much less (random) write actions.
SDCards (as SSDs) which can take much higher amounts of write ops usually
cost significantly more, because they have to bring with a lot of spare
memory for wear leveling over lifetime.
So, it highlöy depends from:
- usage (write access behaviuor)
- SSD card "quality"
