WebSep 28, 2000 · A magnetic disk, for example, has no limit on the number of erase/write cycles for each location, but the finite number of erase/write cycles for any byte location in EEPROM often limits the disk's performance and utility. Today's technology limits the most commonly used EEPROMs to 100,000 to 1 million erase/write cycles because the erase ... WebThis approach will automatically extend the cycling count as the number of erase cycles per sector are cut by half. Additionally, this approach is highly recommended in order to avoid losing data in the event of an unexpected power loss. Another method which can be used to guarantee the appropriate retention time is to refresh the data blocks

I do think the total host writes is "after" amplification, so I think the issue seems to be poor wear levelling algorithm. WebWhen you write a file, new blocks are being written. The used blocks are marked as "dirty". So, if you wrote a 10KB file on a 1MB device, it is likely that the 10 KB file will be written all across the blocks in the 1MB device. Only when there are no more "clean" blocks, the flash controller will likely then erase "dirty" blocks.
