AZ,
Depending upon what you're planning on using the thing for, you may with to be cautious about the SSD; they're something of an overhyped technology. Though they use lower power than physical drives do when at idle, they actually use more power during read and write cycles, so if you plan on doing anything that uses the disk a lot, an SSD can actually shorten battery life.
SSDs also degrade over time. In your stated scenario, you should be fine, because you have to do the equivalent of writing the entire disk's contents a couple thousand times for the degradation to become dangerous, but it is there and it is a factor in drive longevity.
Also, something to be absolutely aware of and careful about with SSDs: Don't ever yank power out from underneath them. If they're in the middle of a write cycle when you do that, the block data and checksum will not agree, because generally the data is written and then the checksum updated. (all of this is internal to the drive, having to do with how the drive detects blocks that have degraded over time and need to be removed from service and replaced with spare blocks; none of this has anything to do with what OS or filesystem you're using).
Nutshell: When the drive restarts, it checks the block data and checksums, and if they disagree, the drive assumes that the block has failed and removes it from service, placing a spare block into service in its stead (even though in this case the block is fine and the write was just interrupted before the checksum could be updated). If there are no more spare blocks left to put into service, the drive declares itself dead well before its expected lifecycle ends.
Some higher-end SSDs have cleverness built in to mitigate this, but they're not in the consumer-grade market yet, AFAIK.
