not on an nslu2 but on my main laptop 3 years ago i got a 2.5in
CF-to-IDE converter cradle and put the fastest 8gb CF card in it that
i could get at the time (200x "professional" grade for cameras). i
used it even as swap (without self-destruct problems), for six months
straight. but, i found that there were truly dreadful pauses of up to
20 seconds at a time, every 10 mins or so. apparently this was a
known problem, discovered more generally a couple of years later when
SSD drives became more common.
the CF card's sector size, and those of SSD drives, is far smaller.
the smaller sector size tended to fuck up ext3's automatic defragging,
amongst other things which you could, if you really wanted to, find
out as a mere historical curiosity. i understand that these issues
have now been fixed.
so, yeah - if you want something reliable, make sure it's for use with
professional digital cameras: they're a paranoid bunch who _really_
don't like their data being lost, so the CF card manufacturers put in
plenty of spare sectors and automatic replacing etc. etc. and then
charge a premium for the privilege.
