if 500gb ssd and i partition it to 400gb and leave 100gb unused.
the lifespan & speed can maintain longer then full partition 500g or die faster due to limited range ?

QUOTE(iZuDeeN @ Dec 28 2020, 09:44 AM) its read/write cycle.. not the space... very clear example. i affraid this happen based on logic.. if you have e.g 100TB of data to write.. if you write to 400GB instead to 500GB.. then yes, you tend to fail faster as each sector is written more on 400GB QUOTE(horns @ Dec 28 2020, 11:39 AM) this is called over-provisioning. it's used to maintain speed and prolong shelf life of nand flash. rupa nya the correct name is OP.have a look at this, https://www.samsung.com/semiconductor/globa...White-paper.pdf that's why we buy ssds that have higher capacities than expected. we will do over-provisioning of 10 to 25%, or more, depending on what they are used for. i like to increase OP |

how to play OP:
if you are working backwards you can always create the spare area partition, format it to TRIM it, then delete the partition. https://www.anandtech.com/show/6489/playing-with-op |
