While modern flash media drive is solid state, it’s life is limited by the number of write cycles it can withstand before it goes “read-only”. When an OEM specified number of flash memory blocks refuse to erase, the device’s controller will set it “read only”. At that point, the device’s useful life is over. | While modern flash media drive is solid state, it’s life is limited by the number of write cycles it can withstand before it goes “read-only”.

With wear leveling and using two drives of the same type, a drive that is twice the size will last roughly two times longer than the smaller drive. This may seem like is a strong vote for using a larger flash drive. However, when backups are considered, drives of twice the size also take twice as long to image and their image files are twice as large. (When using flash media as a boot drive, a practical trade-off should be considered in the 16 to 32GB range.) | With wear leveling and using two drives of the same type, a drive that is twice the size will last roughly two times longer than the smaller drive.
