I'm sure I'm confused here, but I keep reading about Windows Vista's ability to use spare USB flash drives to improve performanace, and now solid state discs made from flash memory (http://www.tgdaily.com/2007/01/03/samsung_32gb_ssd/ ). I'm sure the people that design these are way smarter than me, so can someone please tell me why this is not the linux equivalent of swapon [device of usb stick] And isn't flash memory only good for so many writes? In other words, won't flash memory fail much sooner than a hard drive? Or in still other words, why aren't all linux users regularly typing swapon /dev/sdc1 (or whatever device your usb stick gets mounted on)?
