I suspect that the above attributes were introduced as a group by one
SSD manufacturer.
The list of attributes also includes the following:
99 (63h) Average FHC (Maxtor)
100 (64h) Erase/Program cycles (Maxtor) ... ???
101 (65h) Maximum FHC (Maxtor)
FHC = flying height control ???
Other interesting attributes are ...
241 (F1h) Total LBA Write (IBM)
242 (F2h) Total LBA Read (IBM)

A bit disapointing. Not your fault of course.

Ok, seems temperature is stuck at cooked 32, which means it
does not actually work. My mistake. Speedfan seems to
display temerature though, and it does raise slightly after
power on and makes sense. No idea what it does or where it gets
the data.
Attribute 12 is now 3956, so it might actually be a device
reset count, not a power cycle count. I had one power-cycle
since yesterday, but a number of reboots.
The other attributes are exactly the same as January, except for
234, which is now raw 571364925191.

Ah, found it. Speedfan swaps HD0 and HD1 in display for some reasonm
probably a bug. This means it does not get temperature from the
SSD either.

Attribute 234 looks like it may be multibyte. For example, some bytes
have increased by 7, another has fallen by 5.
