Similarly, by changing how data is written to flash media, MFT dramatically increases the practical amount of data which can be written to any SSD. The traditional random write method overwrites data and is very inefficient. As little as 2/10% of actual erasing and re-writing is expressed as a new data update. Conversely, MFT's linear method of random writing has a constant efficiency, regardless of data size, which is determined by the amount of free space on the drive - the percentage of space not consumed. The performance shown below, with a write/erase efficiency of 30%, typically occurs when free space averages about 20%. As free space rises, so does the total daily permissible write throughput.

This graph below shows the capacity expectations for the Mobi-1000 which uses Toshiba 10,000 erase cycle MLC Flash memory. Other drives will be different. The important point to remember is that if your daily write consumption is less (the vast majority of servers and workstations overwrite 20% of their surface area or less on a daily basis) then practical life will correspondingly expand. With MFT's fifty-fold practical life expansion, the erase-life of most computers is measured in decades or centuries rather than in months and years.
