I had only 1st and 2nd Generation SSD's. With those wear from write access was
a heavy issue. More recent drives should have little worries there, but I read
in many manufacturers descriptions that their drives are "optimized for NTFS
and FAT" - which reads like if they'd blow running ext3/4 or any other decent
journaling system.

When search time is the issue, a SSD is an enormous speedup. The only thing
even faster are Ramdrives - those boxes you plug in DIMM-RAM's - but there
you'll end up with a 16GB drive for 90€, and I doubt you're needing the
600MB/s throughput on read & write that these drives offer.

Personal opinion here: I still have a slight toothache thinking about long-
term reliability with lotsa writing in conjunction with SSD's.
So, as for wotrthwhile: Remember to make backups or get two drives and make a
RAID0, or get 3 and make a RAID5.
But I am paranoid.
Considering search-time might be your Achilles-heel, a SSD should be a major
improvement.

No worries as for fitting: in the worst case doublesided sticky tape will hold
the drive in place. Its doing so in my netbook since 4 years, which is
constantly being lugged around.
Powersupply, noise and heat will also show an amiable change toward the
better.
