RE: SSDs

Evan,

Was in a very interesting session at an IBM AIX tech conf on SSD's a while
back. The price/size part of the equation has a lot of work yet to be done
but it's clear that SSD's is the direction of choice. In time you'll see
laptops that are shipped with mirrored SSD drives since their power
consumption is far less than current platter media.

There was also a discussion about the wearing out of the memory... SSD's
can only be rewritten to so many times before the memory location actually
wears out...there's plenty of alternate space available so this isn't an
immediate concern but it's not the same with platter media.

There was also discussion of the future of SSD's being used as removeable
media for backups similar to how we use thumb drives on a PC today. You
would basically mount/dismount the drive like unix/AIX does all the time and
then perform whatever operations you wanted...keeping in mind it's a helluva
lot faster to copy to disk than tape! :)

I've seen them in use at a couple of sites and apparently doing well.
I deliberately say apparent as there has not been a lot of analysis
carried out beyond the customer being satisfied they are doing what
they paid for ?

How did you assess the benefit you obtained from them ?
What was the criteria you use in your assessment ?

SSDs are cool but we found them expensive and what little benefit we got
from them was overshadowed by money spent elsewhere on the machine.
