Also when in these situations it might be handy to 'hibernate' the 
system, saves battery and you have it up and ready very quick.

Shouldn't SSD speeds also affect some overall performance aspects? Like 
it or not you are always writing/reading something from disk at a 
certain point no? I'd imagine for example you would have some benefit 
for multitrack hard disk recording et sim.
Of course the benefit/cost assessment is another, in my opinion open, 
matter.

That's my same doubt with SSD (together with their current price). 
Because adoption (and widespread of it) is rather recent, it's hard to 
really assess reliability and risk factors.

  On the other hand I have a couple of very bad experiences with 
_external_ hard disks where the arm borke and failed, could be because 
even in laptops hard disks are much better protected than in mobile 
cases. Fortunately these were 'travel' disks and I had backups.
I got somewhat 'paranoid' with digital backups when a few years ago I 
lost some stuff: no hardware failure, I deleted it by mistake: as silly 
as it may sound it does happen, and when it does it bites!

The only real reason to use NTFS is that realistically it is more 
portable, so if you read need to read the disk from an OS that won't 
easily read the ext-* family go for NTFS. But i guess that would be for 
more of a backup/portable/transfer disk.
