Over provisioning 10/25/25(Sat)03:33:10 No.107001816
Over provisioning Anonymous 10/25/25(Sat)03:33:10 No.107001816 Archived
Is over provisioning still neccessary for SSDs? SSDs always have around 10% of the drive's storage inaccessible. Do you still need to leave some of the drive space free these days?

No, they do that for you with ghost space. When you buy a consumer SSD you can fill it up "to its maximum" and you'll still have some space left over in reality

Yes.
Because the free space may not be contiguous it allows for files being copied to the drive to be copied and stored contiguously most of the time and then later rearranged when the drive is mostly idle.

Depends on capacity. It was a serious problem when SSDs came in 64GB capacities. When you filled it up it had only a few GB of over provisioning which caused unholy amounts of write amplification that could kill your SSD in a year.

Modern 1TB SSD already has like 100GB of over provisioning already so you can fill it up and it will survive for a decade.
