Earlier this month Samsung released version 4.9.7 of their SSD Magician software. Even though it’s not mentioned on their website, this firmware update (DXT0AB0Q) is also available for the Samsung SSD 840, predecessor of the more popular SSD 840 EVO.
You may recall a year ago we published a piece about SSD performance degradation on first generation TLC solid state drives. Consider this a follow up to that article even though by now SSD 840 series drives are nearly 4 years old.
