Wear leveling is built into the compact flash card. It hides its true structure from the host hardware and system and randomizes the physical locations of writes. Other solid-state storage media uses similar strategies to ensure writes are spread across the memory, some has it built in like Compact Flash, others have it in the host controller. With wear leveling the data on solid-state media is always fragmented and running a defragmenter on it won't actually defragment the data, though it may appear so to the operating system. Fragmentation on solid-state media doesn't matter because every bit is accessible in the same amount of time and there's nothing like the track to track seek times that spinning media has. -- ----- You received this message because you are a member of the Vintage Macs group.
