As far as I know, all < 4GB microdrives are older technology than the current crop of 4GB+ drives. The old tech is slower, much more power hungry, runs hotter, and isn't nearly as shock resistant. I wouldn't reccommend them over solid-state CF cards.
Name brand 1GB solid-state CF cards are relatively cheap these days. I don't know about Singapore, but in the US, Sandisk and other manufacturers offer lifetime warranties so if you do manage to kill it with a swapfile (tougher than you may think with a good name-brand card), you just send it back for a free replacement.
