Just wanted to reply earlier than later while the thread is still fresh.

Before swapping the HDD for a SSD you should migrate the data. You'll need either an external enclosure or USB > SATA cable to connect the SSD. Use some freebie program like EASUS ToDo backup free to clone the partition(s) to the SSD http://www.todo-backup.com/products/...p-software.htm. Select "optimize for SSD" to ensure proper alignment.

To replace your toughbook HDD.

1. Remove battery.
2. Open lid and remove center screw next to the screen, keep this screw separate, it's slightly longer than the others.
3. Close lid, flip over, remove the screw that holds the hdd cover that's in the battery compartment.
4. Remove the two other screws holding the hdd cover.
5. Remove cover, gently lift out the funky foam/tape enclosure holding the hdd.
6. Find the ribbon cable & gently pull the hdd out of the foam 'crate'.
7. Remove the SATA cable from the drive and hook it to the SSD.
8. Reverse the process to assemble.

I can't comment on speed improvement because I immediately replaced the stock HDD with a SSD when I got the laptop but am very sure you'll be amazed with the upgrade.
