> This happens to be wrong on both accounts. Typical flash-memory today is rated at either
10k or 100k - the lower number being for MLC flashes, which are cheaper and therefore can be
expected in your average cheap medium from Fry's.
Well you wouldn't buy the cheapest thing you can find when you go want to use it in a server,
right? So you make sure you get the 'high endurance' versions of the drives with SLC NAND
chips and make sure that you go through a cycle of swapping it out every year or so.
The thing is is that people are actually using flash to help speed up disk access in their
datacenters. This isn't the first time I've heard of people doing this sort of thing.
Personally I work with a lot of flash media. The cheaper stuff. I haven't been here long, but
I've talked to people that have been working here for 20 years. (of course they haven't been
using CF cards that long). Nobody has yet to see any sort of flash media failing that they can
remember. The actual physical connections (the plastic holes for the pins get malformed) get
all screwed up before the any actual data ever gets corrupted.
Were do you get your numbers for the 16M wear leveling? Typically your dealing with media that
is at least 512 megs and soon you'll have a hard time finding new stuff that is under 2 gigs.
I am doubtful that only 16megs out of 2gigs is going to be wear leveled.
