NetBSD & SSDs (without TRIM)

[David Brownlee <abs%absd.org@localhost>]

Obviously TRIM support would be a wonderful thing for NetBSD to have
for modern SSD devices,
to allow disks to more effectively manage and erase unused space.

In its absence I was wondering if there are any tasks that could be
occasionally run to make the drive's
life easier, such as filling all empty space on a disk with all 1's
data (working on the assumption that
the flash's natural behaviour of erasing to all 1s is reflected
through to the data).

Just an idle thought...
