Lifetime depends on the type, but typically about 10,000 writes to each individual bit, they use wear levelling to spread the writes about - you won't be writing to the same bit each time - so assuming you write to the full capacity of the drive every day (unlikely) they'll last about 30 years. Ever hard a hard disk for that long?

Depends on the eee model, they all use SLC for the primary drive. The models with two drives (e.g. the 901) have a 4GB SLC drive and an MLC drive making up the rest of the capacity. However, the newest version of the 901 (and possibly others) come with a single SLC drive. Also, there are now very fast MLC drives - have a look for Runcore - which are faster than typical SLC drives. Finally, the read speed of SLC and MLC is similar it's the write speeds that differ.
