Due to normal wear and tear, there will always be a possibility that the E-Disk^® and E-Disk^® Altima^™ solid state drive encounters bad memory blocks as Flash memory approaches its write/erase cycle endurance limit. Remapping is performed by firmware on the fly to replace logical block address entries that point to bad blocks with new good blocks. BiTMICRO's solid state drives are shipped with a number of good reserved blocks for this purpose.
