Sorry, two thing I forgot to mention; I have swapfile turned off and I run a
bittorrent client a lot of the time. However, with a 1GB/day limit from my
ISP the bittorrent client isn't accounting for much of that 33GB of writes.

Nice! Maybe one day when they're cheaper....

Interestingly I've noticed that USB thumb drives can get a bit warm when
they're being written to. However I got quite a shock the other day when I
was using a 4GB micro-SD card in a USB adapter and filled it with data
(essentially using it as a USB stick). When I unplugged it the card was too
hot to hold! That surprised me. The thermal stresses with
expansion/contraction can't be good for it. I wonder, do SSDs heat up as
much (albeit 'locally')?

Sorry I am now confused - what was the conclusion of this thread?

- Does anyone supply SSDs that will fit into the bay of a Thinkpad
T60? (i.e. in place of my CD/DVD)
(if so - any particular specific recommendations?)
- If so, have all those (bloody rediculous) problems about writing too
much to them been solved yet?
- Has anyone written a utility to defrag SSDs yet (which would
presumably solve the above problem
of SSDs slowing down over time if you write to them too much)?

My default plan would be to remove my CD/DVD from the (Ultrabay in
my) T60
and to put a SSD in there instead. And to then re-install my key
applications so
that they now sit on the SSD, but leave WindowsXP (and possibly my
data??) on the
hard drive.

Cheers

The earlier parts of the thread have expired here, so I can't review
the actual details of your speed complaint...

If you keep the HD and just install the applications to the SSD, a
well-behaved
program shouldn't write much to the SSD drive...but that won't help
the OS stuff.

If boot time is the issue, an option might be to put a second battery in
the drive bay and use sleep mode. If you have a small amount of memory,
you might be able to put the hibernation file on the SSD and use that mode.
If you have a lot of memory, returning from hibernation can take longer
than a boot.

My interpretation of this thread is...
If you have more money than time,
Stick with the EXPENSIVE Intel drives.
Enable the embedded stuff so the system doesn't write the drive so much.
I'm skeptical about the lifetime claims, but hey, we've got more money
than time. It's a no-brainer.
