Where they rate their own flash at 1,000,000 read/write cycles.

The typical flash drive used to be rated for about 10,000 writes, but the better vendors do better. :-)

They've also started doing things like "wear leveling" by rotating the sectors being written to, which help avoid hotspots forming which wear out earlier (ie, the directory entry for / or /tmp). But you need to look for that feature in your flash drives as the low-cost ones typically won't have it!

You can help things out a lot by disabling file access time updating ("noatime" flag to mount), and by using RAMdisks and a no-swap config, as someone else had mentioned.

But I'll repeat my caveat: if you want to run a general-purpose FreeBSD system, you're better off using a hard drive than flash. Save using flash for dedicated appliances where you've taken steps to control writes.


PS: I'm seeing a relatively significant number of 5-8 year old Cisco boxes starting to wear out their flash chips and fail (ie, 3 out of about a dozen or so I've had contact with over the years).
