found ths thread for research, and fast forward to 2013,
to alan1476 comment: "at 1USD a Gb, I will buy them. Its not that far away.'
at ths time, 7/2013 found ssd 256 gb uprade w/ cost for 470. usd(now ths is for laptops, not external ssd), and comes out aprox 2 usd per gb.
from a laptop user perspective(and note, have just learned w/ fast 3 weeks cram reading to catch up w/ the new tech info, and info could understand w/ me not being tech), cant help but decide to go w/ ssd for hard drives; o wow, just reading about intel third gen "i- " processors, eg "ivy bridge"(being faster, lesser demand on battery, and not as hot, ths is very good news esp for mobile laptops.
and for the laptops w/ harddrive SATA 500 gb, 750 gb and 1 T(tera)b, who wants such a big storage stuck on laptop, have learned safer to save files on external storage/ or backup (external harddrives, usb flash drives,or SD(secure digital) cards). note, ths practice was mentioned and learned to me by (freaks)colleagues and forums, again thx comrads.
ps, have to learn how to copy/paste comment(s) for forum comment, grr
