32GB SSD

I've used RiDATA SSDs before (128GB MLC model) and their performance was pretty spotty. The reads were straight enough and you get most of the major perks of an SSD (no moving parts - ideal for a laptop), but their read performance leaves something to be desired. If the OCZ Core and the Samsung MLC SSDs are any indication, then these cheap MLC SSDs are cheap for a reason - they don't match to the performance of their superior SLC brothers.
 
I am looking to run it in a laptop to improve the battery life and also reduce how hot the laptop gets. Also the shock-proof nature of SSD's is appealing for the laptop.

My only worry is that the SSD will be slower than a 5400RPM laptop HDD, or that somehow I will corrupt it by writing/reading too much. I have heard they have a limited write cycle.
 
A reasonable SSD should get significantly better performance than a 5400RPM HDD, especially in reads. In writes, in my experience, the MLC SSDs were pretty spotty and very spikey, but the no-mechanical-parts design of SSDs would appeal to me most, especially with the road-warrior type laptop user.

All SSDs have limited write cycles. MLCs are estimated around 10,000 total writes (as in, the entire SSD and each memory cell was written over 10,000 times) while SLCs are estimated at around 100,000 times. Doubtful even with MLC's 10,000 write limit that with normal use (with the SSD's controller distributing write load over different cells, not just the same one) and with auto defragmentation off that you'll experience that in any reasonable length of time before a normal HDD's MTBF.
